Claims

[Claims for Utility Model Registration] A rotor is inserted into a cylinder sandwiched between both closing materials to form an operating space between the cylinder and the rotor, a vane is slidably inserted into the rotor, and the cylinder , a compression chamber surrounded by a rotor and vanes changes in volume as the rotor rotates;
In a vane compressor that compresses gas sucked in through the suction hole in the compression chamber and discharges it from the discharge hole, the drive shaft of the rotor is rotatably supported on the closing member by a gap-adjustable needle roller bearing, and
A vane compressor characterized in that the gap-adjustable needle roller bearing is fixed to one end in the axial direction with an aluminum spacer interposed therebetween.
