Abstract
The electromagnetic clutch comprises a rotor connected to a drive source, an inner hub connected to a device that follows, an outer plate provided on the outside of the inner hub so as to enclose it, an armature coupled to the outer plate and opposing the rotor, an elastic member provided between the inner hub and the outer plate and adhered thereto, and an electromagnetic coil for, when magnetized, attracting the armature together with the outer plate to make them come into contact with the rotor, and when demagnetized, separating the outer plate and the armature from the rotor. Because of the configuration in which the armature and the outer plate are coupled in a heat-transmissible manner, a part of elastic member is formed so that heat is transmitted from at least a part of the armature to the part of the elastic member as if they are one piece.
