In this embodiment, the expandable member 42 is a cylindrical body whose top surface and bottom surface (both not shown) are closed and whose body portion has a bellows shape, and the entire internal space serves as a filling portion. there is

By filling the filling portion with fluid, the expandable member 42 expands to move the base plate 2c upward, thereby raising the seat portion 2a of the chair 2 fixed to the base plate 2c. Further, by discharging the fluid filled in the filling portion to the outside, the expandable member 42 is contracted to lower the seat portion 2a of the chair 2 fixed to the base plate 2c. With such an operation, the chair 2 can be raised and lowered within the bathtub 8 between the bottom position and the upper position, which is the same height or substantially the same height position as the fixing member main body 20 in this embodiment. It has become. At least part of the upper end of the elastic member 42 may be directly fixed to the chair 2 . Since the slanted frame 24 is slanted, its seat 2a is located near the edge wall 82 of the bathtub 8 (particularly its upper end surface 84) when the chair 2 is stopped in the upper position. As a result, the user can easily enter and exit the bathtub 8 from the upper end surface 84 of the edge wall 82 of the bathtub 8 .

On the other hand, when the chair 2 stops at the bottom position, the seat portion 2a is separated from the edge wall 82 of the bathtub 8, so the edge wall 82 does not become an obstacle for the user during bathing. The movement stop position of the seat portion 2a can be arbitrarily set by adjusting the amount of fluid to be filled or discharged from the filling portion. Also, the fluid is not particularly limited as long as it is a fluid substance, but is water here.

The driving device 3 is a device that drives the operating member 4, and here, it can supply fluid to the filling portion of the elastic member 42 and discharge the fluid inside the filling portion of the elastic member 42. It is a device that can The drive 3 may be a mechanical device that provides fluid to the actuating member 4, such as a pump or fluid line. For example, when the fluid is water, the driving device 3 can be configured as a device that is connected so as to be able to supply water from a conduit for tap water having a predetermined pressure, a valve for water supply and drainage, or the like. The water supply path of the driving device 3 may be separate from the supply path for supplying hot water into the bathtub 8, or may be the same.
