The front upper end surface 1b and the inclined surface 1c are formed so as to be a smooth gentle slope having no step as a whole, so that any point on these surfaces has a downward slope toward the inside of the bowl 6. Thus, there is also an advantage that dirty water (water droplets D) can be directed to the bowl 6 more reliably.

  Further, by attaching the toilet seat 2 and the toilet lid 4 to the toilet body 1 on the same axis, the structure is simplified as compared with the case where there are a plurality of attachment portions to the toilet body 1, and the toilet body 1 directly Since the rotation support portion can be provided at one place, there is an advantage that the number of places where dirt accumulates can be reduced.

  As mentioned above, although preferred embodiment of the toilet bowl with a local washing apparatus concerning this invention was described, various embodiment can be employ | adopted in the range which does not deviate from a summary, without limiting this invention to the said embodiment.

  For example, the upper end surface of the toilet bowl is a flat surface with no inclination or an almost perfect flat surface without bending, and a local cleaning device is placed on the upper surface and the upper surface of the toilet bowl and the lower surface of the local cleaning device are subjected to water repellent treatment. May be. In this case, even if sewage enters the gap between the upper end surface of the toilet bowl and the lower surface of the local cleaning device, the sewage can be removed by flowing water through the gap.

  In the above embodiment, the inclination angle θ1 and the inclination angle θ2 are substantially the same so that the height of the gap is constant. However, even if the inclination angle θ2 is larger than the inclination angle θ1, Good. In this case, since the gap increases toward the upper side of the inclined surface, it is possible to suppress the accumulation or clogging of dirt on the upper side of the inclined surface.

  Moreover, although resin is used as the material of the toilet bowl with the local cleaning device and the local cleaning device, for example, part or all of them may be formed using other materials such as ceramics.

  Furthermore, the toilet bowl with a local cleaning device and the shape of the local cleaning device can take various shapes.
