Abstract
An inner race of a first rolling bearing is fixed to a shaft, and an outer race thereof is fixed to an inner race of a second rolling bearing. In the first bearing, the outer race and rolling elements contact each other on the side of a center of the rolling elements closer to one end side in an axial direction, and the inner race and the rolling elements contact each other on the side of the center of the rolling elements closer to the other end side in the axial direction. In the second bearing, an outer race and rolling elements contact each other on the side of a center of the rolling elements closer to the one end side, and the inner race and the rolling elements contact each other on the side of the center of the rolling elements closer to the other end side.
