ある。 FIG. 1 is a partially cutaway side view showing an example of the rotor structure of a rotary piston engine according to the present invention together with a rotary piston engine to which the rotor structure is applied, and FIG. FIG. 3 is a partial enlarged sectional view of the rotor included in the example rotary piston engine shown in FIG. 1, and FIG. 4 shows the configuration of the rotor included in the conventional rotary piston engine. It is a partially enlarged sectional view shown. In the figure, 25 is an eccentric shaft, 27 is an internal gear, 28 is an oil jet, 30 is a rotor, 31 is a peripheral wall, 3
2 and 33 are side walls, 34 is an outer shell portion, 35 is a boss portion, 37a to 37l are rib portions, and 37v is a corner portion.

Claims

[Scope of utility model registration request]

an outer shell portion consisting of a peripheral wall provided with a plurality of apexes slidingly in contact with the rotor housing and a pair of side walls continuous to the peripheral wall; a boss portion located at the center of the outer shell portion; and a radius from the boss portion. a plurality of rib portions extending radially along the direction and connecting the boss portion and the outer shell portion, and internal teeth meshing with a fixed gear attached to the side housing on one end surface of the boss portion. A gear is attached, a gap is formed between the other end surface of the boss portion and an inner peripheral end surface of one of the side walls, and the gear is disposed near at least the apex portion of the plurality of rib portions. in which the cross-sectional outline along the radial direction of the corner portion located between the other end surface and the inner peripheral end surface is a single unit connecting the other end surface and the inner peripheral end surface. A rotor structure for a rotary piston engine, characterized in that the rotor has a recess formed by an arc of a circle.
