<P>PROBLEM TO BE SOLVED: To provide an electromagnetic clutch that can suppress friction engagement of an armature. <P>SOLUTION: The electromagnetic clutch 1 includes a rotating member 2; an electromagnetic coil 32 that is arranged on a rotational axis O of the rotating member 2 and generates electro-magnetic force; an output mechanism 3 that has the armature 33 to which return force in a direction away from the electromagnetic coil 32 is applied by a return spring 10; a cam mechanism 4 that is juxtaposed along the rotational axis O to the output mechanism 3, and has a control cam 41 that is unable to rotate relative to the rotating member 2, and a cam follower 42 that is able to roll between the control cam 41 and the armature 33; and a relative rotation restricting means 5 that is arranged on an axis of the cam mechanism 4, and that is configured to restrict relative rotation between the armature 33 and the control cam 41 when the electromagnetic coil 32 is in a de-energized state. <P>COPYRIGHT: (C)2012,JPO&INPIT |
