In the event that a moment in a bending direction is generated in a pinion shaft, for example, when a vehicle is involved in a collision or the like, since a bending facilitating portion which is a circumferential groovebends, stress is concentrated hereon, and no large bending stress is generated in any case between a rolling bearingand a support member.
