ABSTRACT:
A carrier is formed with a circular cylindrical supporting part4a. This supporting part4ais formed with a receiving hole4b. A planetary gear5is rotatably received in the receiving hole4. One side part inner peripheral surface and the other side part inner peripheral surface of the receiving hole4ain the peripheral direction of the supporting part4aare each formed of a circular arcuate face having a same radius of curvature as the radius of the planetary gear5. The centers of curvature of the circular arcuate faces forming the one side part inner peripheral surface and the other side part inner peripheral surface, respectively, are spacedly arranged from each other in the peripheral direction of the supporting part4a. Owing to this arrangement, the interval between the one side part inner peripheral surface and the other side part inner peripheral surface of the receiving hole4acan be made larger by a portion equal to the distance between the centers of curvature than the outside diameter of the planetary gear.
