Claims

[Scope of utility model registration request]

A rotary piston fitted in an annular recess of a casing block so as to be reversible in the forward and backward directions, and a sealing member fitted in a fitting groove of the rotary piston to seal between the rotary piston and the casing block. In the rotary piston mechanism, the sealing member includes an elastic sealing member and a resin sealing member overlaid on the elastic sealing member, and the fitting groove of at least the inner circumferential surface of the rotating piston is One of the fitting groove and the fitting groove on the outer peripheral surface is formed into a narrow first groove into which the elastic seal member is fitted and a wide first groove into which the resin seal member is fitted so as to be movable in the width direction. A rotary piston mechanism characterized by comprising two grooves.
