Claims

[Scope of utility model registration request]

A cam ring portion having an elliptical inner circumferential surface and a side block portion that closes one end of the cam ring portion are integrally formed of an aluminum-based metal, and a cylinder that is integrally formed with the cam ring portion and a side block portion that closes the other end of the cam ring. a rear side block attached to the cam ring; a rotation shaft rotatably supported by the rear side block and the side block; a rotor housed in the cam ring section so as to rotate with a small gap between the cylinder and the cam ring section; a rotor contact surface forming portion having an insertion hole through which the rotating shaft is inserted and a rotor contact surface in contact with one end surface of the rotor;
A pair of perfect circular part forming parts forming the perfect circular part have an integrally molded part integrally molded with iron-based metal,
The integrally molded part is made so that the center of the inner circumferential surface of the annular cylinder part and the center of the true circle part of the pair of true circle part forming parts coincide with each other, and the integrally molded part A vane type compressor characterized by being integrally molded with.
