A hook 20 is also rotated to a back part of the cylindrical auxiliary handle 2, and the installing stand 4 is installed on the auxiliary handle 2 in a single operation. In this case, locking projection parts 21 are formed in a plurality at intervals in the circumferential direction in an outer peripheral part of an engaging part 17 of the installing stand 4.
