When the second member 2 comes into contact with the positioning screw member 54 of the hole portion 53 and further swinging is restricted, the operation is stopped. Therefore, the swing angle of the handle 21 and the swing angle of the back portion 20, that is, the posture at the time of bathing can be separated, and the back portion 20 can be swung in conjunction with the swing of the handle 21. Therefore, since it is not necessary to swing the back part 20 separately from the swing of the handle 21, the operability can be improved.

Further, since the handle 21 is provided with a lever 43 for releasing the fixing of the handle 21 at the two swing angle positions of the standing side position and the tilting side position,
It is possible to improve the operability of a series of operations such as the swing of the handle 21 following the release of the fixing by the operation of the lever 43. In addition, since the handle 21 is provided with the lever 71 for releasing the fixation of the upper chair 11 to the lower chair 12, a series of steps of releasing the fixation by operating the lever 71 and then sliding the upper chair 11 through the handle 21 is performed. The operability of the operation can be improved.

Further, since the head 23 is swingable with respect to the back portion 20 and can be fixed at a plurality of angular positions with respect to the back portion 20, the chair upper part 11 is in a reclining state and the head of the bather is held. When the hair is washed while being supported by the head 23, the head 23 is swung with respect to the back 20 and fixed at a desired angular position, so that the angle of the bather's head can be set to a desired angle. it can. Therefore, when performing the hair washing, it is possible to cause the bather to take a preferable posture for performing the hair washing, and it is possible to improve the workability of the hair care by the caregiver.

Further, in order to evacuate the handrails 87, 88 when a bather transfers, etc., the handrails 87, 88 are used.
Are rotated so as to separate the gripping portions 90 and 92 from each other, and are swung so as to be located on the rear side of the head 23. After that, when the hands are released, the handrails 87 and 88 are respectively gripped. Since the holding portions 90 and 92 are urged in a direction of approaching each other, the holding portions 90 and 92 are automatically swung so as to approach each other and become a folded state. Therefore, the gripping portions 90 and 92 of the handrails 87 and 88 which are arranged so as to be swung to be located on the rear side of the head 23 are automatically in a state where they do not obstruct the caregiver, and therefore, the workability of the caregiver is improved. Can be improved.

On the contrary, in order to use the handrails 87 and 88,
The handrails 87 and 88 are rotated so as to separate the gripping portions 90 and 92 from each other, and are swung so as to be located on the front side of the head 23.
7, 88 are urged in a direction to bring the grip portions 90, 92 closer to each other, so that they are automatically swung so as to bring the grip portions 90, 92 closer to each other and can be gripped by a bather. It becomes a state.
