Claims

[Scope of utility model registration request]

An inner tube is placed inside the outer tube,
In a shock absorber, a piston equipped with a valve is brought into sliding contact with the inner circumferential surface of an inner tube, and an oil chamber inside the inner tube communicates with an oil reservoir chamber formed between an outer tube and an inner tube via a bottom valve mechanism. The valve mechanism of the shock absorber is characterized in that both the valve mechanism and the bottom valve mechanism have a valve seat surface that supports a plate valve as a non-annular irregular round surface.
