PROBLEM TO BE SOLVED: To properly secure strength of a supporting member fastened to a case of a transmission through a bolt for rotatably supporting a counter drive gear.SOLUTION: A supporting member 100 of a power transmission device 20 is fastened to a transmission case 22, an extended portion 110e of the supporting member 100 is formed to be overlapped to a counter driven gear 43 when observed from a radial direction, and has a cutoff portion 110n formed so that it does not interfere with a part of the counter driven gear 43. The supporting member 100 has an internal oil passage 117p communicated with an engagement oil chamber 130 of a brake B1, and a bottomed cylindrical rib portion 117 projecting from an annular wall portion 102 along the extended portion 110e. The rib portion 117 is disposed between a fastening portion 111 near the cutoff portion 110n and a differential ring gear 45, and the cutoff portion 110n in the circumferential direction while overlapped to the fastening portion 111 at a bottom portion 117b when observed from a radial direction.SELECTED DRAWING: Figure 6 |
