ジン。[Claims for Utility Model Registration] A seal groove formed in the axial direction at the three biased parts of the rotor is provided with an upper seal and a lower seal, each having a mating surface inclined with respect to the side wall surface of the seal groove. In a rotary piston engine equipped with a Tux seal, the surface of at least one of the upper seal and the lower seal, which is guided by the inclination of the mating surface and comes into contact with the seal groove side wall surface, engages with the seal groove side wall surface. A rotary piston engine featuring matching surface processing.
