<P>PROBLEM TO BE SOLVED: To prevent water infiltration into a closed space through outside air discharge holes for discharging abrasion powder from a dry clutch to the outside while suppressing increase of the axial dimension. <P>SOLUTION: In a hybrid driving force transmission device, the dry multiple-disk clutch 7 arranged in the closed space for connecting and disconnecting the transmission of driving force includes a drive plate 71, a driven plate 72, a friction facing 73, a front cover 60, and a warpage plate 68. The drive plate 71 is spline-coupled to a clutch hub 3. The driven plate 72 is spline-coupled to a clutch drum 6. The front cover 60 has outside air intake holes 66 for taking outside air into the closed space, and the outside air discharge holes 67 for discharging an air flow from the inside of the closed space to the outside air. The warpage plate 68 is provided on the outside air discharge holes 67 of the front cover 60 and has warpage parts 67b for raising the peripheries of the outside air discharge holes 67 towards an outside air discharging direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
