Claims

[Scope of utility model registration request]

(1) A piston rod is inserted into and out of the cylinder, a spring bearing member is fitted to the outer periphery of the cylinder so as to be movable in the axial direction, and a suspended spring is inserted between a part of the piston rod and the spring bearing member. In the hydraulic shock absorber, a worm gear having a feeding portion for the splash receiving member is provided on the outer periphery of the cylinder so as to be freely axially and rotationally movable, and the worm gear is arranged in a direction perpendicular to the worm gear. An initial setting load adjustment device for a suspension spring in a hydraulic shock absorber, wherein the worm is engaged with the spring receiving member, one end is brought into contact with the spring receiving member, and the worm is rotatably supported by the spring receiving member.

(2) The initial setting load adjusting device for a suspension spring in a hydraulic shock absorber according to claim 1, wherein the feeding portion provided on the worm shaft is a cam.

(3) The initial setting load adjustment device for a suspension spring in a hydraulic shock absorber according to claim 1, wherein the feed portion provided on the worm shaft is a screw that is screwed into a screw on the outer periphery of the cylinder.
