るラジアルピストンモータのピストンリング。[Claim for Utility Model Registration] A piston member formed integrally with a piston having a spherical outer peripheral surface and a connecting rod reciprocates into a cylinder hole via a piston ring having an abutment fitted into a ring groove on the spherical outer peripheral surface. A piston of a radial piston motor in which the piston ring is fitted so as to be movable and swingable, and the maximum swing width e1 of the piston ring corresponding to the maximum swing angle of the piston member is larger than 1/2 of the width B of the piston ring. In the ring, the piston ring satisfies the following conditions: r<B/2・sin θ 1 where r: arc radius of the circular arc outer peripheral surface in the outer radial direction of the piston ring θ 1 : satisfies the maximum swing angle of the piston member A piston ring for a radial piston motor characterized by having an arcuate outer peripheral surface.
