<p>PROBLEM TO BE SOLVED: To more satisfactorily suppress generation of gear noise by more properly meshing a counter drive gear, which is connected to an output member of a transmission via a connection member, with a counter driven gear.SOLUTION: In a power transmission device 20, a connection member 60 has a connection part 603 which is connected to a ring gear 37 working as the output member of an automatic transmission 25, and a tubular part 601 which has a spline 601s formed in an outer peripheral surface and is mounted to the outer periphery of a bearing 61 supported by a transmission case 22, and the connection member is supported rotatably around the axis of the automatic transmission 25 by the bearing 61. The counter drive gear 41 which is an annular member formed with gear teeth 41g in the outer periphery is spline-fitted to the outer periphery of the tubular part 601 of the connection member 60 to rotate integrally with the connection member 60.</p> |
