The stopper opens and closes a drain hole(12) of a drain pipe(10) connected to a washstand. The stem is extended from the bottom of the stopper to pull or push the stopper in the axial direction of the drain pipe. The guide blade part comprises a detachable blade(13) and a fixed blade(17). The detachable blade with a joint groove is attached to the bottom of the stopper. The fixed blade is formed on the top of the stem and includes a guide rail(23) which contacts a blade surface(15) of the detachable blade and guides the detachable blade to the right position.
