According to the present invention, in a rotational fluctuation reducing device, a serial connection formed, via an intermediate retainer 36, between a low-rigidity first coil spring 32 and a high-rigidity second coil spring 34 is disposed between a first retainer 16 and a second retainer 18 which form a pair, which are spaced apart from each other in the circumferential direction, and which are made of resin material. The first coil spring 32 and the intermediate retainer 36 are disposed in a bottomed recess 40 of the first retainer 16. During deformation, the intermediate retainer 36 is caused to slide at a radially outer portion of the bottomed recess 40 of the first retainer 16. The second coil spring 34 is housed in a bottomed recess 42 of the second retainer 18. Damping control is performed, in a low-torque range, under low torsional rigidity resulting from the serial connection of the first coil spring 32 and the second coil spring 34, and is performed, in a normal torque range, under high torsional rigidity provided solely by the second coil spring 34. The present invention achieves reduction in abnormal noise due to switching taking place through resin-metal contact and low noise during idling.

An input member 10, which is connected to a drive source, and an output member 12, which is connected to a transmission, are each made of a single press-formed steel plate. A coil spring 14 is disposed so as to be elastically deformable in response to rotational fluctuations between the input member 10 and the output member 12. Retainers 16, 18 for retaining a coil spring are attached to both ends of each coil spring 14, the retainers 16, 18 being injection molded parts made of resin material. The retainers 16, 18 have a groove-protrusion fitting structure and a face-to-face contact structure between opposing faces in an axial direction and opposing faces in a radial direction with respect to the input member 10 and the output member 12, and provide support structures for the input member 10 and the output member 12 by the retainers 16, 18 themselves. It is possible to produce an assembly in which the coil spring 14 is retained, so as to be elastically deformable in response to rotational fluctuations, between the input member 10 and the output member 12 only by means of the retainers 16, 18, without using rivets or welded structures.

The purpose of the present invention is to configure a retainer to serve also as a support structure for an input member and an output member without impairing the primary support function of coil springs, thereby rendering the input member and the output member each in a single-piece structure and enabling the number of parts to be reduced significantly. In the present invention, an input member (10) coupled to a drive source and an output member (12) coupled to a transmission are each constituted from a single-piece press-formed steel plate. Coil springs (14) are disposed to be elastically deformable in response to rotational fluctuations between the input member (10) and the output member (12). On both ends of each coil spring (14), retainers (16,18) for retaining the coil spring are fitted. The retainers (16, 18) are provided with a tongue-and-groove interlocking structure and a surface-to-surface abutting structure between axially opposing surfaces and radially opposing surfaces with respect to the input member (10) and the output member (12), and realize, by the retainers (16, 18) themselves, a support structure for the input member (10) and the output member (12).

Two-stage transmission for electrically driven vehicle
The present invention relates to a two-stage transmission for an electrically driven vehicle including a dog clutch and a friction clutch, and an object of the present invention is to prevent a torque drop when shifting gears. The two-stage transmission for the electrically driven vehicle includes a planetary gear mechanism (12), a dog clutch (28), a friction clutch (30), an armature (26) to switch between the dog clutch (28) and the friction clutch (30), and an electromagnetic coil (31) to drive the armature (26). In the dog clutch (28) and the friction clutch (30), the coupling relationship among the rotational elements of the planetary gear mechanism (12) is set such that the dog clutch (28) is fastened and the friction clutch (30) is not fastened in speed reduction (the first speed), and the dog clutch (28) is not fastened and the friction clutch (30) is fastened in speed increase (the second speed). To prevent the torque drop when shifting the gears, a ratchet-type one-way clutch (50) is disposed such that a rotational phase position of the ratchet-type one-way clutch (50) is coincident with that of the dog clutch (28). When shifting from the second speed to the first speed, since the rotational phase of the dog clutch (28) is adjusted by the ratchet-type one-way clutch (50), the shifting is instantaneously completed without waiting operation for the phase adjustment, resulting in preventing a transmission shock.

HOT PRESS PROCESSING DEVICE AND HOT PRESS PROCESSING METHOD
The objective of the present invention is to eliminate the generation of burrs in a press-formed product even with a configuration in which a high-temperature blank material is subjected to a trimming process, thereby eliminating a burr removal operation performed after forming, and thus achieving a reduction in work man-hours and by extension a reduction in cost. In a press-forming process in which a blank material 3 is shaped while a die 1 is being clamped against a punch 2, a trim part 3a is sandwiched between a trim holding stepped portion 6 and a cut holder 8 while an elastic force of a spring component 9 is being imparted thereto. As a press-forming action of the die 1 progresses, a trimming blade 7 moves in a relative manner along an outer peripheral edge portion 5b of a punch side forming surface portion 5, while the cut holder 8 is being subjected to a pressing force of the trim holding stepped portion 6, counteracting the elastic force of the spring component 9, and in this way the trim part 3a is cut off by being sheared between the trimming blade 7 and a tip end corner portion 5c of the outer peripheral edge portion 5b of the punch side forming surface portion 5.
The present invention relates to a wet multi-plate clutch in which the hydraulic chamber rotates, and which improves gas mileage as a result of reducing the load on a clutch hydraulic oil-driving oil pump for clutch engagement operations and achieves structural simplification as a result of omitting a canceller chamber. The outer circumference of a disc spring (46) is supported by a clutch drum (10) and the inner circumference contacts a disc spring-pressing part (12-1) of a piston (12). The disc spring (46) faces a clutch pack (20) on the side opposite from the piston (12). Advancement of the piston (12) due to hydraulic pressure in the hydraulic chamber (32) is transmitted to the clutch pack (20) via the disc spring (46) and puts the clutch pack (20) in an engaged state. Piston (12)-driving force due to hydraulic oil pressure is enhanced by the lever ratio a/b of the disc spring (46) and is transmitted to the clutch pack (20). The disc spring (46) extends to the disc spring-pressing part (12-1) without interfering with the piston (12) and retracts the piston (12) to disengage the clutch by means of a large return spring force that results from an increase in spring force due to increased spring length.
