Abstract:
1. A shock-absorbing mechanism for a power-transmission device, comprising: a first shaft which transmits torque; a second shaft coupled to the first shaft through a slide bearing, the second shaft being axially relatively slidable with respect to the first shaft, the second shaft being cylindrical; a center bearing arranged at an outer periphery of the first shaft, the center bearing supporting rotatably the first shaft to a vehicle body; and a labyrinth mechanism arranged at the outer periphery of the first shaft, the labyrinth mechanism sealing an inside of the center bearing, an end of the second shaft on a side of the first shaft being disposed axially opposite to the labyrinth mechanism; when the first and second shafts are slid in a direction to approach each other by an axial load input to the first and second shafts, the end of the second shaft colliding axially with the labyrinth mechanism.
