An electromagnetic clutch comprises a rotor rotatable with respect to the center of rotation, an armature facing the rotor with a clearance, a device for generating a magnetic attracting force between the rotor and the armature, a rotating member transmitting a driving force from the armature, and a plate spring for mounting the armature on the rotating member. The plate spring extends in a direction opposite to the center of rotation and has a first end separated from the center of rotation. The first end or a portion in the vicinity of the first end contacts an armature surface facing the rotor, and the plate spring is fixed to the rotating member at a portion other than the portion contacting the armature surface. The armature is supported such that the armature is urged to be separated in a direction opposite to the rotor by an elasticity of the plate spring. |
