PROBLEM TO BE SOLVED: To improve the adhesion property of joint parts and a bathtub cap body and to improve the handling quality and durability of a bathtub cap by adopting a soft resin compsn. consisting essentially of a propylene (PP) resin and an amorphousα-olefin resin as a resin component constituting the joint parts. SOLUTION: The bathtub cap body 1 has a hollow square sectional shape consisting of the PP resin and is formed by connecting plural lines of the bathtub cap bodies 1 by means of the soft and slender joint parts 2 consisting of a soft resin compsn. mainly composed of the PP resin and the amorphousα- olefin resin apart specified intervals in such a manner that the long sides of these bodies do not come into contact with the long sides of the adjacent bodies. Nonslip materials 3 formed in the longitudinal direction at the center of the rear surface of the bathtub cap body 1 are formed by fusing the material similar to the material of the slender joint parts 2 like a belt. As a result, the generation of the cracks in the joint parts and the degradation in the difficulty in slipping are obviated and the hygienic problems accompanying the generation of molds are eliminated.
