PURPOSE: To carry a bathtub to outdoor and to easily assemble it by constituting a bathtub outer part by erecting respective side plates along the inner side of a peripheral frame, forming a bathtub body by a waterproof sheet material, fitting an upper part frame to the outer side of the bent part of the upper end opening edge and performing assembly. CONSTITUTION: The peripheral frame 2 surrounding the four sides is formed on the upper surface of a bottom plate 1 whose plane shape is turned to a rectangular shape and the side plates 5 and 6 are erected along the inner side of the peripheral frame 2 of the bottom plate 1. Thus, the bathtub outer part is formed. The bathtub body 11 formed by the waterproof sheet material is formed in the rectangular parallelopiped shape of a volume approximately equal to the content volume of the bathtub outer part. Then, by forming notches from the upper ends of four corners, bent pieces 12 ad 13 for which opening end edge parts are bent to the outer side are formed. Further, the upper part frame 17 is closely fitted to the outer side of the bent pieces 12 and 13 in a cage-like manner and abutted to stopper projections 8 and 9. |
