<p>An electromagnetic shock absorber including a motor with increased usability. Coils 60 of the motor 52 provided in an electromagnetic shock absorber 10 are vertically movable relative to an inner tube 22 that is connected to a wheel-side member, and are elastically supported by springs 74, 78, such that movement of the coils relative to permanent magnets 56 in the axial direction, which is caused upon movement of the coils relative to the inner tube, is allowed. Owing to such a construction, vibrations transmitted from a wheel of a vehicle to the motor are alleviated, and the motor is sufficiently protected from the vibrations. Further, since the absorber has an unsprung dynamic damper in which the coils function as a mass, the transmission of the high-frequency vibrations of an unsprung portion of vehicle to a sprung portion of the vehicle can be effectively restrained.</p> |
