Abstract

An electromagnetic clutch for separably coupling a drive source and a rotary shaft has a rotor to be disposed in the outside of the rotary shaft concentrically therewith. The rotor is rotated by a drive source and accommodates an electromagnetic coil. The electromagnetic clutch has an armature plate that is attracted toward the rotor by an electromagnetic force generated by the electromagnetic coil so as to adhere to the rotor. Furthermore, the electromagnetic clutch has a coupler for coupling the armature plate and the rotary shaft to each other. The coupler includes a center part to be coupled to the rotary shaft and an elastically-deformable outer part for coupling the center part to the armature plate, the outer part being extended from the center part and elastically deformed when the armature plate is attracted to the rotor.
