<p>PURPOSE:To easily obtain proper elastic force for axially displacing an armature, and proper elastic force for buffering shock when a rotor is in contact with the armature in an electromagnetic clutch in which a resin elastic member is arranged between the armature and a body to be rotated for supporting the armature displaceably in an axial direction, and the armature can be rotated relatively to the body to be rotated. CONSTITUTION:A transmission body 7 extending in a direction differently from a rotor 4 is fixed to an armature 5. The transmission body 7 is provided with an axial displacement member 9 which displaces the armataure 5 in an axial direction and a rotational direction displacement member 8 which relatively rotates the armature 5 and a body 6 to be rotated, independently on each other. Torque transmitted to the transmission body 7 is also transmitted to the body 6 to be rotated through the rotational direction displacement member 8. When the armature 5 is attracted by the rotor 4, the axial displacement member 9 is compressed. On the other hand, when the armature 5 is in contact with the rotor 4, the rotational direction displacement member 8 is compressed.</p> |
