When the device case 8 is pushed forward A, the inclined guide surface 14b of the fitted portion 14 can be fitted over the inclined guide surface 13b of the fitted portion 13, and the device case 8 can be placed horizontally as described later. It is structured so that it can be easily detached when it is rotated.

  As shown in FIGS. 6 and 7, a seal member 15 is interposed between the rim rear portion 4 a and the front end portion lower surface 8 a of the apparatus case 8. The seal member 15 is made of a waterproof material having elasticity, for example. In this example, the seal member 15 is also wound around the outer peripheral surface of the front end of the air duct 21 as shown by hatching in FIG. 7, so that odor leakage from the duct opening 22 (FIG. 3) is prevented at the same time. .

  Next, the assembly operation will be described.

  A seal member 15 is attached in advance to either the front end lower surface 8a or the rim rear upper surface 4b of the device case 8. Thereafter, the apparatus case 8 is leveled and pushed into the storage opening 12 along the lower guide surface 25. At this time, when the inclined guide surface 14b of the fitted portion 14 gets over the inclined guide surface 13b of the fitted portion 13, the fitting surfaces 13a and 14a are smoothly fitted. Further, at this time, by adding an operation of horizontally rotating the device case 8, the fitting portion 13 and the fitted portion 14 located at the left and right diagonal positions can be fitted to each of the front and rear sides, and the rim 4 can be fitted. The fitting operation of the device case 8 becomes easy. In this fitted state, the front end portion of the local cleaning nozzle 6 is positioned in the nozzle opening 20, and at the same time, the front end portion of the blower duct 21 is positioned in the duct opening 22. Thereafter, the device case 8 is fastened to the support frame 9 with the screw tool 23. By this fastening, as shown in FIG. 6, the seal member 15 is pressed between the front end lower surface 8a of the device case 8 and the rim rear portion 4a, so that both the gaps 26 are reliably sealed.

  On the other hand, at the time of disassembly for maintenance, the device case 8 is removed from the support frame 9 and then pulled out from the storage opening 12. At this time, the device case 8 is first pushed in and is slightly rotated horizontally by the amount of engagement between the fitting portion 13 and the fitted portion 14 as indicated by an arrow a in FIG. The fitting portion 13 and the fitted portion 14 at the positions P1 and P2 can be removed one by one on the front and rear sides, and the disassembling work can be performed smoothly even in a narrow toilet space.

  Thus, during assembly, even if there are variations in component dimensions, the positioning strength of the device case 8 relative to the rim 4 can be increased, and the front end lower surface 8a of the device case 8 is in close contact with the seal member 15. The water stop strength is increased at the same time. As a result, the assembly work is accelerated and the sealing can be performed stably, so that the sewage does not enter the gap 26 and the cleaning becomes very easy.

  In this example, since the front end lower surface 8a of the device case 8 is inclined downward toward the rear B, the device case lower surface portion 8b excluding the front end lower surface 8a can be disposed at a position lower than the rim rear upper surface 4b. As a result, the height of the device case 8 can be reduced, and there is also an advantage that the size of the upward projection of the local cleaning device 5 can be reduced to achieve compactness.

  Further, in this example, the front end portion lower surface 8a is inclined by reducing the thickness of the front end portion of the apparatus case 8, but the upper surface of the front end portion is not mounted with devices such as the local cleaning nozzle 6 or the like. Since the front end portion lower surface 8a is supported from below by the elastic seal member 15 on the rim rear portion 4a, even if the front end portion is thin, the entire device case 8 is strong. There is no problem.
