Abstract
An electromagnetic shock absorber including: (a) a wheel-side member; (b) a body-side member movable relative to the wheel-side member; and (c) a damping force generator with an electromagnetic motor including stationary and movable elements movable relative to each other. The damping force generator can generate, based on a force generated by the motor, a damping force acting against a relative movement of the wheel-side member and the body-side member. The motor has an axis extending in a both-members-relative-movement direction as a direction of the above-described relative movement. The stationary element is supported by the wheel-side member via an elastic body, to be movable relative to the wheel-side member in the both-members-relative-movement direction. The electromagnetic motor allows relative movement of the stationary element and the movable element upon movement of the stationary element relative to the wheel-side member.
