| 摘要 |
A shock absorber adapted for use in attenuation of vibration for prevention of sudden increase or decrease of attenuating force of plate-like open/close valve to thereby improve a rideability of a vehicle, the shock absorber disposed with a piston (57) having a cylindrically closed housing filled with fluid where an attenuating force (P) is generated by a fluid resistance caused by the fluid moving through orifices (62), the shock absorber comprising: a valve (2) formed to horizontally move on upper/bottom surfaces of the piston to thereby open and close the orifices (62); a guide unit (3,4) disposed between the valve and the piston to enable the piston to horizontally move and to prevent the piston from breaking away to the other direction; and an actuating unit for horizontally changing a force applied to the fluid to move the valve when the piston is moved toward an expanding direction. <IMAGE> |
