PROBLEM TO BE SOLVED: To provide a shifting operation device of an automatic transmission capable of being downsized.SOLUTION: A torque limiter 66 is provided between a gear mechanism 36 for rotation and a motor 33, and thereby excessive torque input from a drive motor 33 for shifting to the gear mechanism 36 for rotation cannot be allowed to be transmitted by the generation of slipping when the torque is more than or equal to specified torque. Accordingly, required strength of the gear mechanism 36 for rotation or the like can be reduced, and a shifting operation device 1 can be downsized. The torque limiter 66 limits transmission torque by frictional engagement between a first cone member 71 and a second cone member 72, and thereby the limiter can be of a simple structure and reduce the costs. |
