PROBLEM TO BE SOLVED: To make the joint of a spool shaft and a slider, constituting a reciprocatively moving structure of the spool, compact without causing looseness. SOLUTION: The slider B is constituted of a slider body 8, an engaging member 24 inserted into the slider body 8, and a plugging member 9 comprising a cap nut for preventing the engaging member from coming off. A whirl- stopping part 6a at the rear end of the spool shaft 6 is inserted into a D-shaped through hole 8c of the slider body 8, and a screw member 17 is inserted into a through hole 6b formed at the whirl-stopping part 6a. The screw part 17c of the screw member 17 is screwed in a screw hole 8d of the slider body 8, and the head part 17a of the screw member 17 protruded from the slider body 8 to a concave part 8b is engaged to the tip part 17b at the opposite side by a loosening-preventing member 25 composed of a nut of a different material by screwing. The screw member 17 is composed of the head part 17a, the tip part 17b at the opposite side and the screw part 17c having the whole length formed into the same diameter.
