The present invention relates to a clutch for a compressor. The clutch for a compressor according to the present invention includes: a pulley (100) which is rotated by a belt connected to an engine of a vehicle, and comprises a cylindrical inner bridge (102) and an outer bridge (104) having a groove (104) formed at an outer circumferential face; a field coil assembly (200) which is inserted between the inner bridge (102) and the outer bridge (104), and generates magnetic force by an external power source; a disc (400) which is closely attached to or separated from one side of the pulley (100) by the magnetic force generated by the field coil assembly (200), and delivers rotary force of the pulley (100) to the compressor (30); and a hub (500) which delivers the rotary force of the pulley (100) to the compressor (30) under the state that the disc (400) comes in contact with the pulley (100) while being combined with the disc (400). A disc contact surface (110) where the pulley (100) comes in contact with the disc (400) is formed by being concave inwardly in the direction of the compressor (30) from one side of the pulley (100). According to the present invention, the clutch for a compressor has the effect of improving strength of the pulley without increasing operation noise of a bearing by moving the groove and the bearing of the pulley toward a disc friction surface, by changing a combining structure of the hub. |
