Claims

[Claims for Utility Model Registration] (1) Two torque transmission paths using a gear mechanism are provided between the input gear and the output gear, and the number of intermediate shafts in each transmission path is different by one; A torque limiter unit characterized in that a two-way torque limiter with different set torques depending on the direction is interposed between the gear and the gear, and one-way clutches with opposite directionality are interposed in the middle of each transmission path. (2) Two torque transmission mechanisms using gear mechanisms are provided between the input gear and the output gear, and the number of intermediate shafts in each transmission path is different by one, so that there is a difference in the set torque in the middle of each transmission path. A torque limiter unit characterized in that a one-way torque limiter is interposed, and one-way clutches having opposite directions are interposed in the middle of each transmission path.
