There is provided the anti-loosening spacer 51 between the screw lock nut 50 and the inner race 10a of the first bearing for drive pinion 10, such that it is moved forward by a rotation of the screw lock nut 50, and there can exist the specified magnitude of backlash delta in the rotational direction between the anti-loosening spacer 51 and the drive pinion shaft 13 at the beginning of the rotation of the screw lock nut 50, and the specified magnitude of backlash delta can be eliminated according to the rotation of the screw lock nut 50. Accordingly, the screw lock nut 50 can be properly prevented from being loosened by this locked spacer 51. <IMAGE> |
