Electromagnetic clutch for vehicle, has extension portion arranged in contact with curved portion of leaf spring from direction opposite to rotor, and inclined portion applying pressure force to armature plate to press plate towards rotor

摘要

The clutch has an electromagnetic coil attracting an armature plate (20) towards side of a rotor. Another rotor transmits rotational force transmitted from the side of the plate to rotational axle (2) of a compressor. A leaf spring (51) has an inclined portion (51g) applying a pressure force to the plate when the rotational force is transmitted from the plate to the latter rotor via the spring to press the plate towards the former rotor. The latter rotor has an extension portion (40b) arranged in contact with a curved portion (51e) of the spring from direction opposite to the former rotor.
