Abstract
When an armature plate is attracted to a rotor so that the turning force of the rotor is transmitted to the armature plate, the turning force of the armature plate is transmitted to a main shaft via a plate spring. An angle (hereinafter referred to as a slope angle) formed between the plate spring and the armature plate is set so as to be not smaller than 10° and not larger than 63°. Therefore, since the slope angle is larger than the slope angle (about 3°) of the general electromagnetic clutch, the torque increase effect increases about 5 percent as compared with the general electromagnetic clutch, and also an excessive pressing force of the plate spring does not develop.
