The purpose of the present invention is to improve assemblability when assembling an input gear shaft 23R, an output gear shaft 25R, and at least one intermediate gear shaft 24R to a reduction gear casing 20. In the present invention, when assembling an input gear shaft 23R, an output gear shaft 25R, and at least one intermediate gear shaft 24R to a reduction gear casing 20a, 20br which is divided in the axial direction, the slide amount of at least one gear shaft when the same is assembled to the reduction gear casing 20a, 20br is different than that of other gear shafts, and as a result of this configuration, it becomes possible to perform position adjustment when assembling the gear shafts to the casing, and assemblability can be improved as compared to cases where all the gear shafts are assembled to the casing simultaneously. |
