HOT-WATER WASHING SEAT DEVICE

PROBLEM TO BE SOLVED: To facilitate the inclined installation of a stool by forming an inclined plane under a specified state at a corner section formed by the rear and side face of a main-body case while specifying an angle. SOLUTION: Inclined planes 7 inclined so as to be placed on the front side towards approaching to the side faces of the main body case 3 of a hot-water seat washing device 1 are formed at corner sections formed by the rear 4 and side faces of the case 3 while angles shaped by the faces 4, 7 are set in 10-30 deg.. The intersections of the faces 4, 7 are placed near bolt mounting sections 8 fixed to a stool 21, and the lowering of strength due to the reduction of the installation areas of the mounting sections 8 is prevented. The intersections of the faces 7 and the side faces of the case 3 are placed near the intersections of the side faces and the extension of the front of the case 3, and bearing sections for the stool 2 can be fitted on both sides of a front in the case 3. Accordingly, even when the stool is tilted and installed to a unit wall surface, interferences in a low tank, etc., at the rear of the stool can be prevented, and a distance between the front end section of the stool and the wall surface determined by the National tourist hotel standard law can be ensured easily.
