Claims

[Scope of utility model registration request]

An aluminum alloy rotor for a rotary piston engine having a concave rotary recess on its outer circumferential surface, and a ceramic plate formed in a tapered shape so that the thickness becomes thicker toward the end surface at the bottom of the rotary recess. A rotor for a rotary piston engine characterized by being laid in a cast state.
