[Modification]
Here, a modified example of this embodiment will be described with reference to FIG. FIG. 10 is a rear view showing the first opening 142 of the toilet device 101 according to the modification of this embodiment.
In a modification of this embodiment, as shown in FIG. 10, the first opening 142 of the toilet device 101 is processed into a substantially perfect circle shape. In this modification, a water supply pipe connection portion 91 a and a second water supply pipe connection portion 91 c are installed at positions facing the first opening 142 . By processing the shape of the water immersion suppression means 44 shown in FIG. 9 so as to match the shape of the first opening 142, it is possible to use the lid portion in this modification as well.

Compared to the first opening 42 of the first embodiment, the first opening 142 of this modified example has a hole with a larger area formed in the rear wall surface 141, but a reinforcing wall (not shown) is provided, deformation thereof is suppressed unless excessive pressure is applied to the rear wall surface 141 . Further, the substantially perfect circular opening of the first opening 142 of this modified example can be formed more easily than the substantially elliptical hole of the first opening 42 of the first embodiment.

According to the toilet bowl device 1 of this embodiment described above, the following effects can be obtained.

The toilet device 1 according to the present embodiment is configured to include the cleaning mechanism portion 9 and the toilet portion 2 having the accommodation portion 4 for accommodating the cleaning mechanism portion 9 at the rear portion.
More specifically, the housing portion 4 of the toilet device 1 is configured to have a first opening 42 formed in the rear wall surface 41 thereof and through which the first water supply pipe 92 is inserted. In addition, the washing mechanism portion of the toilet device 1 has a first connecting portion 91a formed opposite to the first opening portion 42 at its rear portion and capable of connecting the first water supply pipe from the outside of the first opening portion. It was configured to have
Thereby, the first water supply pipe 92 of the present invention can be connected to the first water supply pipe connection portion 91a from the outside of the housing portion 4 . Therefore, in the cleaning mechanism part 9 of the present invention, unlike the conventional cleaning mechanism part, it is not necessary to connect the water supply pipe and the connecting part inside the cleaning mechanism part 9, and the height can be suppressed.
Therefore, according to this embodiment, it is possible to provide the toilet device 1 capable of keeping the height of the washing mechanism portion 9 low.
Further, according to the present embodiment, the height of the toilet device 1 itself can be reduced by keeping the height of the washing mechanism portion 9 low. As a result, the entire toilet device 1 can be made compact.

Further, the washing mechanism portion 9 according to the present embodiment is formed at its rear portion facing the first opening portion 42 , and the second water supply pipe 96 arranged inside the housing portion 4 is connected from the outside of the first opening portion 42 . The configuration further includes a connectable second connection portion 91c.
More specifically, the shape of the first opening 42 is a substantially elliptical shape extending toward the second water supply pipe 96 . As a result, it was impossible to connect the second water supply pipe to the second water supply pipe connecting portion with the conventional through hole, but the first opening 42 of the present invention makes it possible.
Therefore, according to the present embodiment, by enlarging the opening on only one side, an opening having a region necessary for connecting the second water supply pipe 96 and the second water supply pipe connection portion 91c is formed. As a result, according to this embodiment, the size can be minimized.
Further, according to this embodiment, the shape of the first opening 42 can be changed to a substantially perfect circle. In this case, it is easier to form the opening than in a substantially elliptical shape.

Further, the accommodating portion 4 according to the present embodiment is configured to have a water intrusion suppressing means 44 arranged in the first opening portion 42 and formed so that the water supply pipe can be inserted therethrough. As a result, water can be prevented from entering through the first opening 42 when the toilet device 1 is washed.
Therefore, according to this embodiment, it can be applied to toilets installed in shower room spaces such as overseas and hotels.
Further, according to the present embodiment, the water ingress suppression means 44 also functions as a reinforcing material for the first opening 42, and the strength of the rear wall surface 41 can be maintained.

In addition, the accommodation portion 4 according to the present embodiment is configured to further include a reinforcing wall 43 extending forward from the lower portion of the first opening portion 42 . The reinforcing wall 43 is integrally formed with the rear wall surface 41 and the toilet bowl portion 2 . Thereby, the strength of the rear wall surface 41 can be maintained as compared with a conventional toilet device having no reinforcing wall.
Therefore, according to the present embodiment, the reinforcing wall 43 can strengthen the rear wall surface 41 of the housing portion 4 , so that deformation of the rear wall surface 41 can be suppressed. As a result, the size of the opening (through hole) of the conventional toilet device can be made larger. As a result, the work can be performed while the hand is inserted into the first opening 42, and the work of connecting and locking the first water supply pipe 92 and the second water supply pipe 96 can be easily performed.
