<p><P>PROBLEM TO BE SOLVED: To prevent increase of slippage time and reduction of transmitting torque by preventing sticking of an armature plate and a rotor friction surface of an electromagnetic clutch. <P>SOLUTION: The armature plate 110 of the electromagnetic clutch has an outer disk plate part 118 and an inner disk plate part 119 combined at a disk combing part 20 and slit 117 to effectively form a magnetic path provided on a center line of a circular shape of the combining part 20 to form the friction surface 110a. A plurality of grooves 120 curving in a rotating direction are provided from an inner diameter side toward an outer diameter side on the friction surface. The friction surface 110a rotates while slipping on a friction surface of the rotor and actively shaves off sticking component of facing material generated on the rotor friction surface to maintain the surface in a normal condition and prevent sticking. <P>COPYRIGHT: (C)2003,JPO</p> |
