To provide a vehicle power transmission device having a compact bearing.
A damper shell 36 is supported by a front shell 16a via a sealed bearing 44 so as to rotate relative to the front shell 16a. An outer race 44a of the sealed bearing 44 is supported by an inner peripheral part 36a of the damper shell 36. An inner race 44b of the sealed bearing 44 is supported by an inner peripheral part 16g of the front shell 16a. The outer race 44a of the sealed bearing 44 is supported by an inner peripheral surface 36e of the inner peripheral part 36a of the damper shell 36. As compared with a bearing 116 having an inner ring 116b supported by an outer peripheral surface 106b of an inner peripheral part 106a of a damper input member 106, the position of the sealed bearing 44 can be appropriately arranged on an inner peripheral side of a damper device 10, and the diameter of the sealed bearing 44 can be reduced further. The sealed bearing 44 can be made compact, and the mass and the inertia thereof can be reduced.
