摘要：
A thrust yoke is fixed into a second recessed portion of a base with adhesive. The second recessed portion has a first surface to be in contact with the bottom surface of the thrust yoke, and a second surface axially opposing the bottom surface of the thrust yoke with a gap therebetween. The thrust yoke has a bent portion at its radial end. The bent portion is bent downward. The thrust yoke also has a protruding portion extending downward from the bent portion. The protruding portion axially opposes the second surface of the second recessed portion of the base with a gap therebetween.
