Claims

[Scope of utility model registration request]

A cylinder 1 filled with oil is fitted with a piston 3 having a damping force generating mechanism 14 at its tip, the other end of which is fixed to a mounting bracket 15 having a space 16, and the tubular structure is slidably inserted into the cylinder 1. A piston rod 2, a pinion gear 2 that is rotatably fitted into the piston rod 2, has a damping force adjustment valve 10 fixed to its tip, and has the other end protruded into the space of the mounting bracket 15, 16.
1 is fixed to the lower adjustment iron 9, a large gear 22 that meshes with the pinion gear 21 and is fixed in the space 16 of the mounting bracket 15,
A flexible system 23 whose one end is fixed to the large gear 22 to rotate the large gear 22; a flexible system 2 whose inner end 25 is fixed to the large gear 22;
A damping force adjustment device for a hydraulic shock absorber, which is comprised of a spiral spring 24 that applies a force in the direction of rewinding 3 to a large gear 22.
