[0020]

As is apparent from the above description, according to the present invention, a frame formed in a rectangular shape by a strength member is locked on the upper part of the main body, a sheet for supporting a patient is stretched on the frame, and the frame is provided. Since the cover that covers the main body is rotatably connected to the main body, the frame reinforces the main body, and the holding force of the seat and the cover increases. Therefore, the main body and the cover can be made lightweight and simple, and the installation space can be reduced. Further, since the front portion of the main body protruding forward from the cover is divided so as to be detachable, a space for carrying and storing is reduced. In addition, the hand shower is housed inside the main body so that it can be protruded and retracted, and the shower head is detachably locked to the front part of the main body, so that the hand shower is not exposed to the outside when not in use and quickly when used. Can be taken out. Also, after the hot water and the water sent from the supply source are separately pressurized by the pump, the pressure is reduced to a predetermined pressure, and these are mixed at a predetermined ratio. It is possible to always obtain hot water with a stable temperature. In addition, since the outflow pressure by the pressure reducing valve is set to about 1.5 to 2.5 Kg / cm ² , the hot water spouting from the nozzle gives an appropriate stimulus without causing pain to the patient. Further, when the mixed water (hot water) obtained by mixing the hot water and the water has an abnormally high temperature, the flow of the mixed water (hot water) is shut off in advance, so that the extremely hot water does not flow out of the nozzle. Further, when the temperature of the hot water becomes abnormally low before the hot water is supplied to each nozzle, the hot water is discharged to the outside. And so on.
