Claims

[Scope of utility model registration request]

A rotating shaft, a rotor rotated via the rotating shaft, a large number of vanes attached to the rotor so as to be able to protrude and retract in a substantially radial direction, a cam ring that accommodates the rotor with the vanes attached, and a cam ring that holds the cam ring in place. The cam ring has a pair of front and rear side plates that form a pump chamber on the inner periphery of the cam ring, and a housing that accommodates these side plates or the rotor, and is attached to the rotor when the rotor rotates. The vanes sliding are pressed against the inner circumferential surface of the cam ring, and the change in volume between the vanes at that time causes working gas to be introduced into the pump chamber through the suction passage provided in the front side plate, and to be applied. In a vane compressor configured to pressurize and discharge to the outside via a discharge passage provided in the rear side plate, the clearance between the cam ring and the rotor at the small circular arc portion of the cam ring is determined by the front A vane compressor characterized in that the vane compressor is formed in advance with a step in the axial direction so that the side has a larger diameter than the rear side.
