Claims

[Claims for Utility Model Registration] (1) A rotating sleeve rotatably supported by a center housing, a rotor that rotates at an eccentric position of the rotating sleeve, and a vane that is fitted in and out of the rotor. In the rotary compressor, reinforcing portions continuous in the circumferential direction are formed in a portion including both axial end surfaces of the center housing or both side portions excluding both end surfaces, and are symmetrical with respect to the center in the axial direction, The thickness of the reinforcing portion in the radial direction is 1.5 to 3 times the thickness of the thin wall portion without bolt through holes in the intermediate portion of the center housing, and the width of the reinforcing portion in the axial direction 5 to 15% of the direction length, and when the center housing is projected onto a coaxial peripheral cylinder surface, the projected area of the thin portion is 60% of the total projected area.
A center housing of a rotary compressor characterized by the following. (2) The center housing of a rotary compressor according to claim 1, wherein the bolt through holes of the center housing are arranged at equal arc intervals with respect to the axis of the center housing.
