Claims

[Scope of utility model registration request]

In a piston device in which a connecting rod and a piston are connected by a ball joint, the piston is provided in the axial direction of the piston, and
a hollow part with a spherical part formed at the bottom; a spherical body of the connecting rod inserted into the hollow part so as to form a spherical pair; and a part of the hollow part provided on the outer periphery of the piston below the spherical part. It consists of an annular groove forming a communication part to the piston, and a substantially C-shaped spring fitted into the annular groove from the outside of the piston, and the protrusion formed on the C-shaped spring passes through the communication part and connects the spherical body. A piston device characterized in that it is configured to support.
