Claims

[Claims for Utility Model Registration] Fixing of a rotary piston engine in which a fixed gear having a flange and external teeth meshing with the internal teeth of the rotor of the rotary piston engine is fixed to the engine housing by the flange. The gear structure is such that a spring pin is fitted into the flange portion to position and fix the fixed gear to the engine housing, and further allows the fixed gear to move freely in the radial direction and restricts movement in the thrust direction. A fixed gear structure for a rotary piston engine, which is characterized by a fixed gear structure.
