When a plurality of bathers rise from the hot water, the caregiver may perform the operations described above in reverse order.

  In addition, in the present Example, although the operation method which returns a moving body to the one initial position shown on the right side of FIG. 5 one by one was demonstrated, the trolley | bogie 10 can be moved to any one side of bathtub 3a-3d. For example, it is not necessary to return the moving body 4 to the one initial position. For example, when a bather is bathed in the bathtub 3d, the caregiver transports the carriage 10 on which the bather is boarding to the side of the bathtub 3d, and thereafter performs a nursing operation for bathing and bathing as described above. The moving distance of the moving body 4 in the state where the bather is held (the distance that the bather is hung and moved) is shortened. That is, it is also possible to take a method in which the carriage 10 is moved alongside the bathtub desired to be raised from the hot water, and the moving body 4 is moved to that position to raise it.

  The bathing care assisting device or chair according to the present invention is suitably applied to a facility for bathing a plurality of bathers in one large bathtub, and a slight modification to a facility for bathing one bather in each of the plurality of bathtubs. Therefore, it can be easily applied and, of course, can also be applied to bathing facilities in the home where one bather takes a bath in one bathtub.
