PROBLEM TO BE SOLVED: To provide a bathing care support device by which the weight to be supported by the device is reduced when a person to be cared is bathed and which can be applied to a facility where several persons to be cared can be bathed in one large bathtub.SOLUTION: The bathing care support device 1 can be freely moved up and down in and out of the bathtub 3 and can be freely carried between the inside and the outside of the bathtub 3, while a chair 2 in which a bather seats himself is maintained. It has: a moving body 4 which can be freely moved between the outside of the bathtub 3 and above the bathtub 3 while maintaining the chair 2 an attachment and detachment mechanism 5 which can freely attach and detach the chair 2 to and from the moving body 4 a lifting mechanism 6 with which the chair 2 is connected through the attachment and detachment mechanism 5 and which can freely moves the chair 2 up and down and an in-bathtub travelling mechanism 7 which is arranged on the chair 2 and makes the chair 2, separated from the moving body 4 by operations of the attachment and detachment mechanism 5 in the bathtub 3, freely move in the bathtub 3 by having contact with the bottom face of the bathtub 3. When the chair 2 is held by the moving body 4 or is in the process of being attached or detached to or from it outside the bathtub 3, the in-bathtub travelling mechanism 7 is positioned at a height where it can not be in contact with the floor. When it is lowered into the bathtub 3, it is positioned at a height where it has contact with the bottom face of the bathtub 3.COPYRIGHT: (C)2012,JPO&INPIT【課題】被介護者を入浴させる際に装置が支持すべき重量が軽減され、さらに、一個の大浴槽に複数の被介護者が入浴可能な設備にも適用容易な、入浴介護補助装置を提供する。【解決手段】入浴介護補助装置1は、入浴者が着座した椅子2を保持しながら浴槽3内外で昇降自在および浴槽3内外間で搬送自在であって、椅子2を保持しながら浴槽3外と浴槽3上の間を移動自在な移動体4と、椅子2を移動体4に着脱自在な着脱機構5と、椅子2が着脱機構5を介して接続され椅子2を昇降自在な昇降機構6と、椅子2に設けられ、浴槽3の底面と接触することにより、浴槽3内で着脱機構5の操作によって移動体4から離脱した椅子2を浴槽3内で移動自在にさせる浴槽内走行機構7と、を有し、浴槽内走行機構7は、椅子2が浴槽3外で移動体4に保持又は着脱されている間は、接地不能である高さに位置し、浴槽3内に降下さ
