Accordingly, the pillow portion 18 is held in a fixed state with respect to the head and neck side mat portion 13a by the U-shaped metal fitting 23 being pressed against the lower surface of the plate-like member 14 by the elastic force of the two compression coil springs 25 and 25. Is done. For the compression coil spring 25, a spring having an appropriate elasticity characteristic is selected so that the pillow portion 18 does not move unnecessarily with respect to the head and neck side mat portion 13a due to its own weight or the like applied to the pillow portion 18.

  The dimension of the side in the longitudinal direction of the U-shaped metal fitting 23 is larger than the dimension of the width in the short direction of the mat long hole 16 and the long hole 17, and the dimension of the side in the short direction is the short length of the mat long hole 16 and the long hole 17. Designed to be smaller than the width in the hand direction. Further, when the pillow portion 18 to be described later is attached and detached, the corner portion 23b of the U-shaped metal fitting 23 is caught on the periphery of the long hole 17 so that the smooth attachment and removal operation of the pillow portion 18 is not hindered. Both corners 23b and 23b of the character-shaped metal fitting 23 are formed into curved surfaces (see FIG. 7A).

  Of course, both the corners 23b may be formed to have an inclined surface as shown in FIG. The shape of the entire pillow holding member 22 is not limited to a substantially U-shape (the U-shaped bracket 23), and the number of the rod-shaped members 20 (the pillow mounting screws 21) fixed to the mounting bracket 19 is also two. Instead, only one rod-shaped member having an enlarged diameter may be employed. In short, the upper surface of the pillow holding member 22 is uniformly pressed against the lower surface of the plate-like member 14 by the elastic force of the elastic body 24 (compression coil spring 25). Can be held in a fixed state, the shape of the pillow holding member 22 and the number of the rod-like members 20 may be in any form.

  Next, the operation of the pillow portion 18 of the bathing wheelchair 1 will be described. When the pillow part 18 is moved in the longitudinal direction of the back support part 5 and when the pillow part 18 is rotated with respect to the back support part 5, the pressure contact force of the U-shaped metal fitting 23 acting on the lower surface of the plate-like member 14 is applied. It is only necessary to apply a force exceeding the level to the pillow part 18 and manually move and rotate the pillow part 18 in the desired directions. Even a person who is unfamiliar with the handling of the bathing wheelchair 1 is very easy to use the pillow. The part 18 can be appropriately moved and rotated according to the body shape and medical condition of the bather.

  In FIG. 5, the pillow portion 18 and the U-shaped metal fitting 23 indicated by the alternate long and short dash line indicate the state after the pillow portion 18 indicated by the solid line is moved downward (in the direction of arrow C) with respect to the back support portion 5. It is. The movement of the pillow portion 18 with respect to the longitudinal direction (upward and downward) of the back support portion 5 is a position where the mounting bracket 19 of the pillow portion 18 contacts the upper inner wall surface 16a of the mat long hole 16 (hereinafter referred to as an upper limit position). And within the range of the position where it abuts against the lower inner wall surface 16b.

  When removing the pillow part 18 from the back support part 5, the pillow part 18 at the substantially upper limit position with respect to the back support part 5 is rotated by approximately 90 ° clockwise (in the direction of arrow D in FIG. 5), The longitudinal direction center line of the mat long hole 16 and the long hole 17 and the longitudinal direction center line of the U-shaped metal fitting 23 substantially coincide with each other (the state of the pillow portion 18 shown by a solid line in FIG. 6). The pillow portion 18 is moved somewhat downward to a position where the entire metal fitting 23 can pass through both the long holes (for example, the pillow portion so that the U-shaped metal fitting 23 reaches the position indicated by the alternate long and short dash line in FIG. 6). 18 is moved downward).

  When the pillow portion 18 is moved downward and the upper surface 23a of the U-shaped metal fitting 23 and the lower surface of the plate-like member 14 are brought into a non-contact state, the U-shaped metal fitting 23 is moved in the direction of the attachment metal fitting 19 by the elastic force of the compression coil spring 25. The pillow portion 18 is pushed and biased, and the pillow portion 18 can be removed from the back support portion 5. In addition, when the pillow portion 18 is moved downward, the lower surface of the peripheral plate-like member 14 where the long hole 17 is formed and the upper surface 23a of the U-shaped metal fitting 23 are slightly in contact with each other. However, since the both corners 23b of the U-shaped metal fitting 23 are formed in a curved shape as described above, the corners 23b are not caught on the inner peripheral edge in the longitudinal direction of the long hole 17, and the elastic force of the compression coil spring 25 is used. The character-shaped bracket 23 is pushed up and biased toward the mounting bracket 19 so that the pillow portion 18 can be removed smoothly.

  Next, an operation when the pillow part 18 is attached to the back support part 5 will be described. For example, the pillow portion 18 is pressed against the head and neck side mat portion 13a so that the U-shaped metal fitting 23 faces the position and direction indicated by the one-dot chain line in FIG. The pillow portion 18 can be fixed to the back support portion 5 only by performing an operation of rotating the pillow portion 18 in the counterclockwise direction (the direction of arrow E in FIG. 6). As described above, since both corners 23b of the U-shaped metal fitting 23 are formed in a curved surface shape, both corners 23b are caught on the inner peripheral edge in the longitudinal direction of the long hole 17 even when the pillow 18 is rotated counterclockwise. The rotation of the pillow part 18 is not hindered, and the pillow part 18 can be attached smoothly.

  As an alternative to forming both corners 23b of the pillow holding member 22 into a curved surface or an inclined surface, an angle formed by the lower surface of the plate member 14 and the inner circumferential wall of the long hole 17 is omitted in the drawing. You may comprise so that a part may be processed into a curved surface form or an inclined surface form.

  Then, the bathtub 32 which bathes a bather using the wheelchair 1 for bathing of Example 1 is demonstrated. A hot water storage tank 33 is integrally formed in the bathtub 32, and an opening 34 is formed on one side of the bathtub 32. The opening 34 of the bathtub 32 is closed by the back support 5 of the bathing wheelchair 1 on which the bather sits, and the hot water is transferred from the hot water storage tank 33 to the bathtub 32 via hot water transfer means (not shown).
