PROBLEM TO BE SOLVED: To provide a home bathtub for a person who is cared, capable of reducing a work load applied to a person who cares.SOLUTION: A bathtub comprises: a bottom surface having a structure and a shape formed of a backrest part of a chair, a seat part, a front side seat part support part and a footrest frame part and left and right side surfaces in a longitudinal direction. A fulcrum rod for rotating the bathtub in the longitudinal direction is installed in a direction orthogonal to the longitudinal direction of the bathtub bottom surface on a seat part rear part of an outside and lower side of the bathtub, and a support structure for supporting the fulcrum bar is provided. For maintaining the bathtub in a horizontal state and in which hot water is filled, the bathtub is supported by the fulcrum bar and the outside support structure of the backrest part. A bathtub support part for maintaining the bathtub in an inclination state in which the backrest part is vertical and the seat part is horizontal, and for controlling rotation of the bathtub from the position in the horizontal state to the position in the inclination state, and rotation from the position in the inclination state to the position in the horizontal state, is installed between the support structure for supporting the fulcrum bar on outside of the bathtub and the outside support structure of the backrest part.COPYRIGHT: (C)2016,JPO&INPIT【課題】 介護者の作業負荷が軽減できる被介護者用の家庭用浴槽を提供する。【解決手段】 浴槽は、椅子の背もたれ部、座部、前方座部支持部及び足載せフレーム部の構造と形状を有する底面とその長さ方向の左右の側面から構成される。浴槽外部下側の座部部分後方に、浴槽を長さ方向に回転させる支点棒が浴槽底面の長さ方法と直交する方向に設置され、当該支点棒を支える支持構造が設けられており、湯を満面に張った水平状態の浴槽を維持するために、当該浴槽は支点棒及び背もたれ部の外部支持構造で支持されてなり、背もたれ部が垂直かつ座部が水平にある傾斜状態に浴槽を維持し、かつ浴槽の水平状態の位置から傾斜状態の位置までの回転と浴槽の傾斜状態の位置から水平状態の位置までの回転を制御する浴槽支持部を浴槽外側部の当該支点棒を支える支持構造と当該背もたれ部の外部支持構造の間の位置に設置してなる構造を有する。【選択図】図2
