Claims

[Scope of utility model registration request]

a housing having a cylinder block having a plurality of cylinders; a front end plate facing the cylinder block and supporting a drive shaft;
A swash plate is disposed in a crank chamber formed between the cylinder block and the front end plate, and is attached to the drive shaft so as to have a variable inclination angle. It has a rocking plate that reciprocates and a balance ring that is locked to a boss portion of the swash plate, and changes the stroke of the piston by changing the inclination angle of the swash plate to change the compression capacity. In the variable capacity compressor, the balance ring has a first hole extending in the radial direction, and the boss portion has a second hole extending in a direction slightly different from the direction in which the first hole extends. A hole is formed, a spring pin having elasticity is press-fitted in the radial direction through the first hole and the second hole, and the balance ring is locked to the boss portion. variable capacity compressor.
