Claims

[Scope of utility model registration request]

A support member for the adjuster is provided with its tip facing the oil chamber in the outer cylinder from the outside of the side surface of the outer cylinder, and a cylindrical member with a small diameter that is coaxial with the support member is inserted and fixed into the inner cylinder. The oil chamber in the inner cylinder and the oil chamber formed between the inner cylinder and the outer cylinder are communicated through the orifice, and the needle is inserted into the orifice, and the adjuster rod is inserted into the support member. - The needle is provided so that it can move forward and backward in the radial direction of the outer cylinder, and the needle is biased by a return spring so that its head touches the tip of the adjuster rod and moves forward and backward, and the orifice area is made variable at the tip. The damping force adjustment device of the constructed hydraulic shock absorber.
