ソーバ。[Claims for Utility Model Registration] (1) A control valve disposed in a side passage allows communication between an upper oil chamber and a lower oil chamber in the cylinder divided by the piston. In a shock absorber formed to be able to change the rebound damping force generated when sliding inside the cylinder, the opening end of the side passage on the lower oil chamber side allows the pressure side flow of hydraulic oil into the side passage. A check valve is disposed at the open end, and a sub-valve is disposed at the open end so as to be independent of the main valve disposed at the piston section. Shock absorber. (2) The shock absorber according to claim 1, wherein the side passage is formed inside the piston rod from the lower end to the vicinity of the lower end. (3) The shock absorber according to claim 1, wherein the sub-valve is disposed on a piston nut screwed onto the lower end of a piston rod. (4) The shock absorber according to claim 1, which is a utility model, and comprises a leaf valve in which a main valve and a sub-valve are stacked. (5) The shock absorber according to claim 1, wherein a main valve and a sub-valve face each other with a single valve stopper interposed in between.
