Abstract:
PROBLEM TO BE SOLVED: To provide a driving force transmission device for restricting occurrence of irregular sound due to self-excited vibration when a slip fastening occurs to cause a dry type clutch friction surface to be slid.SOLUTION: There are provided a multi-plate dry type clutch 7 arranged at a driving force transmission system a piston 82 and a piston arm 83 stroked in a clutch fastening direction with hydraulic force when the multi-plate dry type clutch 7 is fastened, a return spring 84 for applying a biasing force of clutch releasing direction to the piston arm 83 when the multi-plate dry type clutch 7 is released, and elastic seal members 89, 89 resiliently deformed in compliance with a stroke operation of the piston arm 83. The elastic seal members 89, 89 are provided with a piston retainer 88 fixed to an arm extremity end part 83b of the piston arm 83 and contacted with clutch plates 71, 72 when the multi-plate dry type clutch 7 is fastened to transmit the clutch fastening force. A ring-like rubber member 101 for applying a normal attenuation to a peripheral member of the multi-plate dry type clutch 7 is arranged between the piston arm 83 and the piston retainer 88.SELECTED DRAWING: Figure 2
