PURPOSE: A shock absorber is provided to block the noise and the shock since the raise of a piston rod is restrained and a hydraulic stopper does not bump with the bottom of a rod guide. CONSTITUTION: A shock absorber comprises a cylinder and a hydraulic stopper(60). The hydraulic stopper restricts the excessive tension of a piston rod(54), which is guided to a rod guide(56) and reciprocates. The rod guide is extended downwards from the lower end and comprises an extended part(57) which holds the stopper. The hydraulic stopper comprises a main body(62) and a stop ring(64). The main body is fixed to the outer surface of the piston rod and comprises a groove on its edge. The stop ring is installed on the groove of the main body and the outer circumference of the stop ring is formed as a slope similar to the inner circumference of the extended part. |
