<p>PROBLEM TO BE SOLVED: To reduce a drag torque and stabilize an action in disengagement in an electromagnetic two-way clutch. SOLUTION: An inner shaft, an intermediate shaft, and an outer shaft are arranged from the rotary shaft center. Electromagnetic clutch units are assembled between the inner shaft and the intermediate shaft and between the intermediate shaft and the outer shaft, respectively. The respective units are engaged with each other by attaching armatures 107 and 207 by the electromagnetic force. The armatures are provided in the inner shaft and the intermediate shaft in the inside unit and the outside unit respectively. When the armature is separated from a separation spring in the disengagement, a regulation mechanism, which regulates the movement in the separation direction to a prescribed value or less for holding the interval between the armature and the attraction face is provided in the same rotary shaft to the rotary shaft having the armature. No rotation speed difference is generated between the armature and the regulating mechanism so that, even if the armature touches the regulation mechanism in the disengagement, no drag torque is generated. By this constitution, can avoid the abrasion and heating of the armatures can be avoided to stabilize the action.</p> |
