になつているギア取付構造。[Claims for Utility Model Registration] The bearing B is attached to the shaft 12 supported by the fixed frame 11 by the bearing B1 externally fitted on the end.
The gear mounting structure supports an idling gear G5 adjacent to the shaft 12 and with its movement in the axial direction restricted, the gear supporting portion of the shaft 12 having a smaller diameter than other portions. A stepped portion 12a is formed on the shaft 12, and the stepped portion 12a restricts the movement of the idling gear G5 in the direction away from the bearing B1 under conditions where the idling gear G5 can freely rotate. , while regulating the axial movement of the shaft 12 with a retaining ring 14 that is engaged in a retaining groove 13a formed in the inner peripheral surface of the inner ring 13 of the bearing B1 . A gear mounting structure configured to restrict movement of the idling gear G 5 in a direction toward the bearing B 1 under conditions in which the idling gear G 5 can freely rotate.
