Abstract
A shock-absorbing mechanism for a power-transmission device includes a cylindrical driven-side shaft coupled to the driving-side shaft through a constant-velocity joint to be axially relatively slidable with respect to the driving-side shaft, a center bearing for rotatably supporting the driving-side shaft to the vehicle body, and a labyrinth mechanism for sealing the inside of the center bearing. An end of the driven-side shaft on the side of the driving-side shaft is disposed axially opposite to the labyrinth mechanism. When the two shafts are slid in the direction to approach each other by an axial load input thereto, the end of the driven-side shaft collides axially with the labyrinth mechanism.
