<p>PROBLEM TO BE SOLVED: To improve on-vehicle property by making torque capacity adjustable within a wide range, reducing the number of parts, making assembly easy, and attaining light weight and compactness. SOLUTION: This device is provided with torque transmission members 5, a friction clutch placed therebetween, a pump 13 operated by moving of an armature 15, an electromagnet 21 to move the armature 15, and an actuator 9 to press the friction clutch through a pressing member 11 by receiving pumping pressure of the pump 13. In this case, pressure receiving area 81 of the pressing member 11 is made wider than pressure receiving area 82 of the armature 15.</p> |
