Claims

[Scope of utility model registration request]

A cylinder, a rotor that is rotatably provided in the cylinder and defines a compression chamber, and a rotor that is rotatably fitted into an annular recess formed on the rotor-side end surface of one side block that forms one side of the cylinder. a control member mounted thereon, and a sealing member made of at least an elastic sealing member mounted on the control member, the control member rotating between a partially operating position and a fully operating position to determine when to start compression. In the variable capacity vane type compressor to be controlled, the elastic seal member is provided with a hollowed out portion, and at least a portion of the elastic seal member is fitted into a wall surface of a fitting groove of the control member into which the portion is fitted. A variable capacity vane type compressor characterized by being provided with a rotation prevention protrusion that makes surface contact with the .
