PROBLEM TO BE SOLVED: To provide a gear box attaching structure with a motor, capable of suppressing scattering of built-in gears caused by disengagement even when vehicle shocks or the like apply an excessive load on a frame member and the frame member is bent to press the gear box with the motor.SOLUTION: A gear box 61 includes a case body part 63a including a reduction gear group 64 for transmitting a driving force from a motor 62 to a rotary shaft 64f and fixed to a right side frame 21R, a motor fitting part 63b for fitting the motor 62 to the case body part 63a, and a fragile part 63c between the case body part 63a and the motor fitting part 63b. The fragile part 63c can be broken to separate the motor 62 from the case body part 63a when the deformation of the right side frame 21R applies a pressing force. The rotary shaft 62a of the motor 62 is connected coaxially and separately with a rotary shaft 64a1 of a worm gear 64a in the reduction gear group 64.SELECTED DRAWING: Figure 4 |
