PROBLEM TO BE SOLVED: To provide a power transmission device which can improve the rigidity of a mount part without increasing weight.SOLUTION: A cylindrical part 61 of a front transfer case 60 has a mount part 80 which is connected with a mount bracket with bolts, and the mount part 80 has a plurality of mount boss parts 81, 82 and 83 and a plurality of ribs 84, 85 and 86. Furthermore, the mount part 80 uses an external peripheral face of the cylindrical part 61 as a bottom part, and is formed into a box shape which is opened at a support boss part 73 side in a vehicle left-and-right direction with an erecting wall part 62 as one side part. The mount boss parts 81, 82 and 83 are extended to the support boss part 73 side in the vehicle left-and-right direction from the external peripheral face of the cylindrical part 61, and have seat faces 87 on the same plane. The ribs 84, 85 and 86 are extended to the erecting wall part 62 side in the vehicle left-and-right direction from the external peripheral face of the cylindrical part 61, and connect the mount boss parts 81, 82 and 83 to one another.SELECTED DRAWING: Figure 6 |
