Vane compressor

A vane compressor comprising:

• a cylinder block in which a cylinder chamber having an oval inner wall on an inner surface thereof is formed;
• and
• a rotor rotatably provided in the cylinder chamber, wherein
• the rotor includes
• a rotor main body that rotates in the cylinder chamber,
• a plurality of vanes whose base ends are supported by a plurality of vane slots formed in the rotor main body and that are provided so as to be able to protrude from the rotor main body,
• coil springs disposed between bottoms of the vane slots and the vanes to urge the vanes toward the oval inner wall, and
• guide members each of which has a press-in end that is pressed into a bottom of one of the vane and the vane slot and an accommodated end that is to be accommodated in an escape hole provided on a bottom of another of the vane and the vane slot, and is inserted into the coil spring to prevent the coil spring from bending,
• when an outer diameter of the guide member is denoted by a, an inner diameter of the coil spring is denoted by b1, an outer diameter of the coil spring is denoted by b2, and an inner diameter or an inner width of an accommodation portion for the coil spring is denoted by c, an inequality (b1−a)<(c−b2) is satisfied, and
• a first seating diameter of a first contact portion at an end of the coil spring on a side of the accommodated end is larger than a second seating diameter of a second contact portion at another end of the coil spring on a side of the press-in end.
