<p>PROBLEM TO BE SOLVED: To reduce a device in cost, and make the device small in size by reducing component parts in number, making its structure simple, and enhancing operating performance in assembly in a driving force transmitting device which electrically controls torque transmission between both rotating parts. SOLUTION: This device is provided with a friction clutch 10c performing torque transmission between both rotating members, a control means 10d permitting the friction clutch 10c to be frictionally engaged therewith, and with a cam means 10e which is actuated by the friction clutch 10c so as to allow the friction clutch 10c to be frictionally engaged therewith, and a current main clutch means can be eliminated by letting the cam means 10e be operated with respect to the friction clutch 10c, component parts can thereby be reduced in number, its structure can be made simple, operating performance in assembly can thereby be enhanced, the device can be lowered in cost, and furthermore, the device can thereby be made small in size.</p> |
