Claims

[Scope of utility model registration request]

A cylinder, a rotor that is rotatably installed in the cylinder and defines a compression chamber, and a rotor that is rotatably held by a side block that forms one side of the cylinder, and that has a fully operating position and a partially operating position. a control member and a member that rotate between the members to control the compression start timing; a torsion coil spring that is locked at one end to the control member and partially biases the control member toward the operating position; A coil spring is loosely fitted into a boss protruding from the side surface opposite to the rotor of the one side block, and a locking part formed on the other end is fitted into a retaining groove formed on the end surface of the boss. A variable capacity vane type compressor in which at least one of the retaining groove and the locking part of the torsion coil spring is provided with a protrusion. A holding structure for a torsion coil spring in a machine.
