Claims

[Scope of utility model registration request]

A sub-cylinder is provided on the main cylinder, and a piston rod that is inserted into the main cylinder through the sub-cylinder is sloped with a piston that slides inside each cylinder. The shock absorber is provided with a port that allows fluid flow to communicate with the atmosphere, and connects the lower chamber of the sub-cylinder with the atmosphere, and connects the upper chambers of both cylinders with each other via a relay pipe, the shock absorber comprising: The fluid flow path from to the upper chamber of the bushing ring via the relay pipe is provided with an outgoing path and a return path through which the fluid can flow in opposite directions due to the expansion and contraction movement of the piston rod, and the outgoing path and the return path are A shock absorber characterized by each having variable orifices.
