ータハウジング。A cage consisting of a rotor housing having a multi-arc inner circumferential surface and a side housing with sealing members interposed along the inner circumferential surface on both sides of the rotor housing. In the rotary piston engine, an insert member is fitted into the exhaust port opened in the rotor housing with a gap between the insert member and the port wall, and secondary air is supplied to the exhaust port through the gap. A passage is provided in the rotor housing near the sealing member, and a secondary air control valve is provided in the secondary air passage communicating with the upstream side of the secondary air passage, and the secondary air passage and the sealing member are connected to each other. A rotor housing for a rotary piston engine, characterized in that the rotor housing between the rotor housings is provided with a heat insulating part that blocks heat of exhaust gas that has entered the secondary air passage section from being conducted to the sealing member when the secondary air supply is stopped. .
