Abstract

PURPOSE:To improve the process for production and to provide the inexpensive decorative board for a bathtub by forming the decorative boards for covering the outside walls surface of the bathtub as extrusion molded goods. CONSTITUTION:An ABS resin for molding the decorative board 10 is first extruded from a main line and a soft vinyl chloride resin forming an upper soft contact part 13 and a lower soft contact part 14 is then extruded from a sub-line along this extruded resin, by which two-color extrusion molding is executed. The resins are extruded to the extrusion molded goods having the same sectional shape in the longitudinal direction of the bathtub. Molding of a large quantity is executed by the same molds in spite of a change in the longitudinal sizes. Productivity is thus good. While an upper mounting part 11 is inserted into a notched part 9 for detaining, this part is lifted. The decorative board 10 is then shaken around the position of the upper mounting part 11 as a fulcrum toward the bathtub 5 side to place and fit the lower mounting part 13 on and into a part 3b to be detained. The upper soft contact part 13 is clamped by a rear side perpendicular surface 6a and a notched perpendicular surface 9a. The lower soft contact part 14 is pressed by its own weight of decorative board 10 to the part 3b to be detained. Then, these parts are elastically deformed respectively to prevent the vibration of the decorative board 10.
