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, this piston device includes a piston formed in the axial direction with a hollow part with a continuous spherical part at the bottom, and a position in the hollow part of the piston that is opposite to the spherical part. The spherical body of the connecting rod is inserted up to the spherical body, a ring is brought into contact with the lower hemisphere side of the spherical body, and a sleeve is installed in the hollow part and presses the ring onto the spherical surface of the spherical body. A piston device featuring:
