Abstract
A rotor of a vane compressor includes vanes that reciprocates in vane slots, coil springs that urge the vanes, and guide members each having a press-in end pressed into the vane and an accommodated end and inserted into the coil spring. When an outer diameter of the guide member is a, an inner diameter of the coil spring is b1, an outer diameter thereof is b2, and an inner diameter an accommodation hole for the coil spring is c, (b1−a)<(c−b2) is satisfied. A diameter of an end (a first contact portion) of the coil spring on a side of the accommodated end is larger than a diameter of another end (a second contact portion) thereof on a side of the press-in end. According to the compressor, contacts between the accommodation hole and the guide member can be prevented without high accuracy forming of the accommodation hole.
