PROBLEM TO BE SOLVED: To solve problems of a conventional bathtub that is formed by inflating with air, which are a problem of a cutoff for preventing a water leak, a problem of a bathtub taking up space, and a problem of inability to secure a necessary bathtub height.SOLUTION: The bathtub of the present invention includes: a fame body 2 which is for forming the peripheral wall part of the bathtub 1 and which is inflatable with air into a desired shape and a waterproof sheet 3 which covers the frame body 2 to form a bathing space of a recessed shape. The bathtub is characterized in that the frame body 2 is composed of a plurality of annularly arranged frame body pieces 2a, 2b which are formed into a planar shape when inflated with air, and that the respective frame body pieces 2a, 2b of the planar shape are structured with a plurality of air bags 10 which are each inflated into a bar shape in a desired length and a desired diameter when inflated with air, and structured with a means by which the plurality of air bags 10 are arranged in parallel with desired spaces apart.COPYRIGHT: (C)2015,JPO&INPIT【課題】従来の空気により膨らませて形成する浴槽は、水漏れ防止のための止水の問題があり、また、浴槽が場所を取り、また、必要な浴槽高さを確保することができなかった。【解決手段】本発明の浴槽は、浴槽1の周壁部を形成するための、空気により所望の形状に膨らむ枠体2と、この枠体2に被せて、凹状の入浴空間を形成する防水シート3とよりなり、上記枠体2は、空気を入れた時に板状に形成される複数の枠体片2a、2bを環状に配置したものであり、 この各板状の枠体片2a、2bは、空気をいれた時に、所望の長さ及び所望の径の棒状に膨らむ複数の空気袋10と、この複数の空気袋10を所望の間隔を開けて並列して配置する手段とよりなりなることを特徴とする。【選択図】図1
