A plurality of grooves 11 around which the belt is wound are provided on the outer peripheral surface of the base end portion of the pulley 10. The belt is also wound around the crankshaft, and the crankshaft and the pulley 10 rotate in synchronization with the belt. On the inner peripheral surface of the pulley 10, a protruding portion 12 that protrudes from the inner peripheral surface and extends in the axial direction is formed. The protrusion 12 is formed in an annular shape centering on the axis of the pulley 10. The pulley 10 is supported by a compressor shaft 70 of a compressor so as to be relatively rotatable through a bearing 13 provided at a tip portion (left side in FIG. 1).
- the compressor shaft 70 is supported by the engine body 72 by a bearing 71 so as to be relatively rotatable. When the compressor shaft 70 rotates, the compressor enters a driving state and compresses the refrigerant.

- the self-holding type solenoid 50 is used as the solenoid 50, but a solenoid that inserts the pin 60 into the spiral groove 33 only while the coil 53 is energized may be used. According to such a configuration, since the clutch is released only when the coil 53 is energized, the clutch is engaged when the solenoid 50 fails and the coil cannot be energized. Therefore, the compressor can be driven even if the solenoid 50 fails.
- the pin 60 is selectively switched between the inserted state and the pulled-out state by the solenoid.
- the state of the pin 60 is switched by an actuator other than the solenoid, such as a hydraulic actuator. May be.
