ABSTRACT:
The shock absorber includes an oil pressure damper (1), a piston rod (2) and a cushion spring (3), wherein the cushion spring (3) contacts to the piston rod side with an end thereof and another end (6) thereof contacts to a spring receiving face (8) of a spring seat (7). Since the spring seat (7) is integrated with an adjuster (10) by engaging claws (9) with the adjuster (10) and is also integrated with a movable cover (20), the spring seat (7), the adjuster (10) and the movable cover (20) rotate and move to an axial direction as one body. Further, an O-ring (17) is provided in a space formed by an lower end face (15) of the spring receiving face (8) and an inner side arc portion of a flange (11) between an outer face of the oil pressure damper (1) and therewith, the lower end face (15) of the spring receiving surface (8) and the inner side arc portion (16) and is elastically supported by the O-ring (17) in a state that the space formed between the outer surface of the oil pressure damper (1) and therewith is buried in non-looseness.
