Claims

[Scope of utility model registration request]

A piston equipped with a non-return valve that allows the piston to move freely in one direction, and forms an orifice to generate a damping force when the piston moves in the other direction.
The non-return valve is composed of a central annular part that is fitted onto the tip of the piston rond, an outer annular part that goes around the annular part with a gap therebetween, and a connecting part that connects both of the annular parts. A piston structure in a shock absorber characterized by a hot caulked tip.
