Claims

[Scope of utility model registration request]

(1) In the piston portion of the hydraulic shock absorber, which is disposed on the piston rod inserted into the cylinder and is formed to generate a desired damping force by sliding,
The piston portion consists of a sleeve through which the piston rod can be inserted, a piston body inserted in the sleeve, and a leaf valve inserted in the sleeve so as to be adjacent to the port opening of the piston body, A piston portion of a hydraulic shock absorber, characterized in that one end of the sleeve serves as a valve stopper portion, the other end is caulked to form a piston body, and a valve and a valve are integrally formed.

(2) The leaf valve is the expansion side leaf valve and the compression side leaf valve.
A piston portion of a hydraulic shock absorber according to claim 1 of the registered utility model claim, comprising:

(3) Hydraulic pressure according to claim 1 of the utility model registration claim, in which a ring seat is disposed between a valve stopper, which is one end of the sleeve, and a leaf valve, which is opposed to the caulked portion, which is the other end of the sleeve. The piston part of the shock absorber.

(4) A piston portion of a hydraulic shock absorber according to claim 1, wherein the piston portion is formed in a piston rod by screwing a nut onto the tip of the piston rod through which a sleeve is inserted.
