Claims

[Claims for Utility Model Registration] A rotary piston engine having a structure in which a rotor housing and a side housing are fastened together using a large number of tension bolts, the rotor housing having an inner circumferential wall having a trochoidal rotor sliding surface; an outer circumferential wall that surrounds the outside of the inner circumferential wall at a predetermined interval; and an outer circumferential wall that is located in the gap between the inner circumferential wall and the outer circumferential wall, connects both walls, and has a diameter larger than that of the bolt through which the tension bolt is passed. In a rotary piston engine integrally equipped with a large number of through-hole bosses having through-holes, and two plug-hole bosses forming continuous plug holes for attaching spark plugs to the inner circumferential wall and the outer circumferential wall; Some of the through-hole bosses around the plug-hole boss are provided separately from the inner circumferential wall, and some of the through-hole bosses of the separated type are located at the end on the rotation side of the rotor. The rotary piston engine is characterized in that a positioning pin is press-fitted into the through hole and the hole of the side housing.
