Claims

[Scope of utility model registration request]

A piston equipped with a damping force generating mechanism for both expansion and contraction, an inner cylinder on which the piston slides, an outer cylinder arranged concentrically with the inner cylinder, and a piston rod to which the piston is attached at one end. , a front guide through which the piston rod is slidably inserted and supports one end of the inner cylinder and the outer cylinder; a base cuff that supports the other end of the inner cylinder and the outer cylinder; and the piston. A lower oil chamber in an inner cylinder defined between the inner cylinder and the base cap communicates with a lower part of an annular oil chamber defined between the inner cylinder and the outer cylinder and whose upper part is filled with gas. It consists of a communication passage and a compensation valve mechanism provided in the communication passage, and the compensation valve mechanism includes a valve body, a valve seat with which the valve body abuts, and a spring that biases the valve body toward the valve seat. The valve body is brought into contact with the valve seat during the retraction stroke of the piston rod, and the oil liquid is supplied through a plurality of communication passages formed between the valve seat and the valve body that comes into contact with the valve seat. A hydraulic shock absorber configured to cause oil to flow through a gap formed between the valve body and the valve seat when the valve body separates from the valve seat during the extension stroke of the piston rod.
