Claims

[Scope of utility model registration request]

A cylinder, a piston disposed within the cylinder, and a piston rod connected to the piston. A sealing structure for the piston rod of a hydraulic shock absorber comprising a pair of guides provided with a through hole in the piston rod and spaced apart from each other in the axial direction of the cylinder, and a space between the guides. a first sealing member that is fitted into the piston rod and movable together with the piston rod between the guides; and an inner surface of the cylinder and the first sealing member to reduce movement resistance of the first sealing member. a low-friction member interposed between the outer peripheral surface of the
A second seal member connected to the first seal member and defining a sealed space communicating with the through hole of the guide between the first seal member and the piston-side guide, the second seal member being connected to the axis line. and a second sealing member expandable and retractable in the direction of the piston rod.
