<p>PROBLEM TO BE SOLVED: To provide a rotation drive mechanism which can suppress breakage of a motor or the like even when an overload is applied on the motor or the like without increasing the number of components.SOLUTION: A rotation drive mechanism 9 includes a pair of V-belts 94A, 94B which transmit rotation of motors 91A, 91B to side gears 92A, 92B by connecting output shafts 91A1, 91B1 of the motors 91A, 91B and input shafts 92A1, 92B1 of the side gears 92A, 92B. These V-belts 94A, 94B are designed so as to slide and spin out when the overload is applied on the output shafts 91A1, 91B1 of the motors 91A, 91B or the side gears 92A, 92B.</p> |
