The expansion sleeve 120 is capable of changing its cross-section when elastically deformed. When the expansion portion 111 is inserted into the expansion sleeve 120, the expansion sleeve 120 is elastically deformed to expand into the shaft hole of the input shaft 20 of the reduction gear, and the input shaft 20 of the reduction gear can be locked.
