PROBLEM TO BE SOLVED: To eliminate a bolt having a risk of damage due to impact load, by fixing a torque arm and a speed reducer casing.SOLUTION: A torque arm structure 30 includes a speed reducer 14, and a torque arm 32 configured to prevent rotation around the output shaft of the speed reducer. Fitted parts 14a, 14b are provided in a speed reducer casing. In the torque arm 32, provided is a fitting part 34 fitted to the fitted parts 14a, 14b of the speed reducer casing. In a state where the fitting part 34 is fitted to the fitted parts 14a, 14b, the fitting part and the fitted parts are opposed to each other in a rotation direction around the output shaft of the speed reducer 14.SELECTED DRAWING: Figure 1 |
