The main gear hole is opened at the joining surface (54) of the main gear, and the subgear hole is opened at the joining surface (64) of the subgear. The holding member is held while partially contacting the main gear hole and the subgear hole. Also, the holding member is held in the state being deformed by means of the main gear and subgear being offset to mutually different rotational directions, and in the deformed state, has repulsion causing a repulsive force at the contacted portions of the main gear hole and the subgear hole.
