The plurality of abutment members 32 and the plurality of urging elements 33 are arranged such that, in a lateral cross section of the slide member 11, the inner product of the vectors of the urging force acting on each of the plurality of abutment members 32 from each of at least a pair of urging elements 33 among the plurality of urging elements 33 becomes zero or negative.

Provided is a slide bearing, sliding performance of which can be maintained over a long period of time. A slide bearing (1) includes an upper case (2) configured to be attached to an upper support for attaching a suspension to a vehicle body, a lower case (3) rotatably combined with the upper case (2) to form an annular space (7), and an annular center plate (4) and an annular sliding sheet (5) that are disposed in the annular space (7). The center plate (4) has a bearing surface (40) sliding together with the sliding sheet (5) and an annular groove (42) formed on the bearing surface (40) and configured to retain a lubricant. The annular groove (42) has an inner peripheral surface (43a) inclined radially outward from the opening side of the annular groove (42) toward the groove bottom side of the same and an outer peripheral surface (43b) inclined radially inward from the opening side toward the groove bottom side. An intersecting line P between the inner peripheral surface (43a) and the outer peripheral surface (43b) is located closer to the bearing surface (40) side than to a rear surface (41) of the center plate (4).

The present invention provides a thrust sliding bearing in which a dust cover, which covers a piston rod of a thrust-type suspension, is reliably and simply assembled to a lower case superimposed over an upper case, and the mold structure during the molding of the lower case is simple. Provided is a thrust sliding bearing (100) in which: a lower case (120), which rotatably slides around an axial center (C) of an upper case (110), has a plurality of upper tongue pieces (123) that engage with case-side protuberances (113b) of the upper case (110), and a plurality of lower tongue pieces (124) that engage with cover-side protuberances (Da1) of a dust cover (D); and the upper tongue pieces (123) and the lower tongue pieces (124) of the lower case (120) protrude along an axial center (C) of an inner peripheral surface (122a) of a cylinder part (122) provided to the lower case (120), so that the protuberances do not overlap each other along the axial center (C).

Provided is a slide bearing with which it is possible to maintain strength while reducing weight and cost. The present invention is provided with an upper case (2) attached to an upper support for attaching a suspension to a vehicle body, a lower case (3) combined with the upper case (2) so as to enable rotation, an annular center plate (4) disposed between the upper case (2) and the lower case (3), and an annular sliding sheet (5) disposed between the upper case (2) and the center plate (4). The lower case (3) has a cylindrical lower case body (31), a flange part (32) projecting radially outward from the outer peripheral surface of the lower case body (31), and thinning parts (321) formed on the outer peripheral surface of the flange part (32). A plurality of the thinning parts (321) are formed at equal intervals along the peripheral direction on the outer peripheral surface of the flange part (32).
Provided is a seismic isolation device capable of ensuring good seismic isolation performance even under low temperature conditions and improving merchantability. The seismic isolation device 1 includes upper and lower spherical plates 10, 10 and a sliding body 20. The sliding body 20 has: a base portion 21; and upper and lower sliding members 22, 22 provided at upper and lower end portions thereof. A number of holes h0-h6 filled with a solid lubricant 23 are formed in a sliding surface 22a of each of the sliding members 22. The present invention is configured such that, by arranging the holes h1-h6 in a nonlinear manner in an orientation along a straight line H, the width (S3-S2) between the maximum value and the minimum value of a curve representing a variation mode of a cumulative value SumL of the distance passing through the holes h0-h6 for each orientation with the center hole h0 as a reference becomes smaller than that in the case where the holes h1-h6 are linearly arranged in this orientation.
