Abstract
A first rotary shaft and a second rotary are rotatable around a rotation axis. The second rotary shaft has a cylindrical supporting part that covers an end section of the first rotary shaft. A case supports the first and second rotary shafts. A first rolling bearing is disposed between the first rotary shaft and the case and rotatably supports the first rotary shaft. A second rolling bearing is disposed between the supporting part and the first rotary shaft and supports the first rotary shaft and the second rotary shaft such that they are rotatable relative to each other. A transmission part of the second rotary shaft transmits to the second rolling bearing a preload force that pushes the second rotary shaft to the first rotary shaft side. A load-receiving part of the case receives the preload force transmitted from the second rolling bearing to the first rolling bearing.
