Claims

[Claims for Utility Model Registration] 1. A male-side split shaft with a tapered portion formed on its outer peripheral surface, and a female-side split shaft formed in a hollow shape with a tapered surface formed on its inner peripheral surface. In a rotary piston engine drive shaft structure in which the male split shaft and the female split shaft are integrated with the tapered portion and the tapered surface pressed against each other, the taper The taper angle of the part is set larger than the taper angle of the tapered surface,
A drive shaft structure for a rotary piston engine, characterized in that the tapered portion and the tapered surface are pressed together with their entire surfaces in contact with each other. 2. The drive shaft structure for a rotary piston engine according to claim 1, wherein one or more grooves are formed in one or both of the tapered portion and the tapered surface in the axial direction of the drive shaft.
