<p><P>PROBLEM TO BE SOLVED: To provide a driving force distribution device which reduces dragging torque sharply, keeps stable and excellent friction characteristics and durability over a long period of time without processing expensive surface treatment, and also to prevent clutch transmitting torque characteristics from varying. <P>SOLUTION: A driving force distribution device 9 is characterized in that: a paper-made facing is arranged in a sliding surface of one side clutch plate between clutch plates of a second friction clutch 50; the second friction clutch 50 is interposed between an electromagnet 70 and an armature 71; and an engagement of a first friction clutch 40, performing a torque transmission between an input member 20 and an output member 30, is adjusted by directly applying a load that the electromagnet 70 attracts the armature 71 with respect to the second friction clutch 50. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
