Provided is a shock absorber wherein the position of a suspension spring can be set with a simple configuration. This shock absorber is provided with: an inner rod (30); a suspension spring (40) disposed on the outer side of the inner rod; a spring bearing (42) that receives load of the suspension spring; an adjusting screw (51) that limits movement of the spring bearing toward the vehicle body side; and a pin (52) that transmits, to the adjusting screw, the load received by the spring bearing. The shock absorber has, in the side surface of the inner rod, a long hole (34) for inserting the pin.
F16F 9/44 - Springs, vibration-dampers, shock-absorbers, or similarly-constructed movement-dampers using a fluid or the equivalent as damping medium - Details such means combined with temperature correction
F16F 9/32 - Springs, vibration-dampers, shock-absorbers, or similarly-constructed movement-dampers using a fluid or the equivalent as damping medium - Details
In order to protect a protective member equipped with a coil from the load from a suspension spring, a shock absorber (1) is equipped with a cylinder (10), a piston rod (20), a suspension spring (50), a spring receiver (94), and a protector (80). The protector (80) has a coil (81) for detecting the relative positions of the cylinder (10) and the protector (80). One end of the protector (80) is arranged so as not to receive a load from the spring receiver (94).

This suspension device is provided with: a damping device for damping force generated between wheels and a main body of a vehicle; a determination unit 121 which determines whether the vehicle is jumping using the acceleration of the vehicle in the front-rear direction, the acceleration thereof in the left-right direction, and the acceleration thereof in the vertical direction; and an ON time setting unit 126 which, if the determination unit 121 determines that the vehicle is jumping, increases the damping force of the damping device so as to be greater than when the determination unit 121 does not determine the vehicle to be jumping.
