Claims

[Scope of utility model registration request]

In a housing assembly constituted by a pair of side housings, a plurality of rotor housings whose inner peripheral surfaces are trochoidal surfaces, and at least one intermediate housing,
A first eccentric shaft having a plurality of eccentric shaft portions formed at appropriate positions in the axial direction; and one eccentric shaft portion formed at a suitable position in the axial direction and fitted and fixed on the outside of the first eccentric shaft. a drive shaft consisting of a second eccentric shaft;
The drive shaft in a rotary piston engine is configured such that each rotor attached to each eccentric shaft portion of the drive shaft rotates planetarily around the drive shaft, wherein the drive shaft has a first eccentric shaft and a first eccentric shaft. A rotation restriction member such as a key for restricting the relative rotation between the two is provided on the fitting surface with the second eccentric shaft, and the mounting position of the rotation restriction member in the rotational direction of the drive shaft is as described above. A drive shaft for a rotary piston engine, characterized in that the drive shaft is set on the eccentric side of a second eccentric shaft.
