Claims

[Claim for Utility Model Registration] Oil is supplied between the eccentric shaft and the bearing metal from the annular oil groove formed between the stationary gear member and the bearing metal through the oil hole provided in the bearing metal. In the bearing structure of the rotary piston engine, the annular oil groove is applied to the portion of the stationary gear member and the bearing metal located on the opposite side of the spark plug to both axial ends of the stationary gear member and the bearing metal. A rotary piston engine characterized in that a bypass passage is provided that guides oil to a nearby area and joins the oil groove again, and a bolt member for fixing a bearing metal is passed through a portion of the oil groove that is bypassed by this bypass passage. bearing structure.
