The first rib 57 and the second rib 58 are provided at the center of the straight pipe portions 56A, 56B in the left-right direction. The first rib 57 is provided on the front side of the second rib 58. The first rib 57 and the second rib 58 are plate-shaped and extend in the front-rear direction. The left and right plate surfaces of the first rib 57 and the second rib 58 are parallel to the front-rear direction.

When the first rib 57 and the second rib 58 are viewed from the left and right, as shown in FIGS. 5 and 6, they have a rectangular shape. The dimension of the first rib 57 in the front-rear direction is smaller than the dimension of the second rib 58 in the front-rear direction. The first rib 57 and the second rib 58 are connected via a connecting rib 59. The first rib 57 is arranged in the closing parts 42A and 42B and inserted into the fixing part 35. The vertical dimension of the first rib 57 is such that it does not protrude upward from the upper surface 28U of the upper surface portion 28 when inserted into the fixing portion 35. If the first rib protrudes upward from the upper surface of the upper surface portion, it is necessary to provide a recessed portion on the lower surface of the functional portion to avoid contact with the first rib. However, since the first rib 57 is located below the upper surface 28U of the upper surface portion 28, there is no need to provide a recessed portion on the lower surface of the functional portion. The second rib 58 is arranged in the opening 41 . The second rib 58 limits forward movement of the water passage member 50 by coming into contact with the upper surface portion 28 of the entrance 36 .

As shown in FIG. 5, an upper surface rib 61 is provided on the upper surface of the left straight pipe section 56A. The upper surface rib 61 is disposed in front of the first rib 57. The upper surface rib 61 is aligned in a straight line with the first rib 57 and the second rib 58. The front-to-rear dimension of the upper surface rib 61 is greater than the front-to-rear dimension of the first rib 57 and the second rib 58. The upper end of the upper surface rib 61 is located below the upper ends of the first rib 57 and the second rib 58.

As shown in Figs. 5 and 6, a bottom rib 62 is provided on the bottom of the left and right straight pipe sections 56A, 56B. The bottom rib 62 is formed at the left-right center of each straight pipe section 56A, 56B. The bottom rib 62 extends linearly in the front-rear direction. The top rib 61 and the bottom rib 62 are inserted into the closing sections 42A, 42B. The top rib 61 and the bottom rib 62 suppress vertical rattling of the straight pipe sections 56A, 56B in the closing sections 42A, 42B.

An example of the process for fixing the water-permeable member 50 to the toilet body 20 will be described. First, the water-permeable member 50 is inserted from the opening 41 into the blocking portions 42A and 42B. Specifically, the left and right second pipe portions 54A and 54B are inserted forward from the left and right inlets 36. When the second pipe portions 54A and 54B are inserted to a predetermined position, the left and right first ribs 57 are inserted from below into the fixing portion 35. This fixes the water-permeable member 50 to a predetermined position. If the water-permeable member 50 is pushed further forward, the second rib 58 will come into contact with the upper surface portion 28 of the inlet 36. This prevents the water-permeable member 50 from being inserted too far. In this manner, the water-permeable member 50 is fixed to the toilet body 20.

After the water-passing member 50 is fixed to the toilet body 20, the functional part is attached to the toilet body 20. At this time, the flush tank of the functional part is connected to the first pipe part 53 of the water-passing member 50. An assembly force acts on the water-passing member 50. However, by inserting the first rib 57 into the fixing part 35, it is possible to prevent the water-passing member 50 from shifting position or coming out of the arrangement space 40.

According to the embodiment configured as described above, the following effects are achieved. The flush toilet 10 includes a toilet main body 20 and a water passage member 50. The toilet main body 20 has a toilet bowl part 21. The water passage member 50 is attached to the toilet main body 20. The toilet main body 20 has a wall portion 23. The wall portion 23 forms an arrangement space 40 in which the water passage member 50 is arranged. Washing water for washing the toilet bowl section 21 flows into the toilet bowl section 21 through the arrangement space 40. The wall portion 23 includes a fixing portion 35 on the lower surface 28S of the upper surface portion 28 to fix the water passage member 50. According to this configuration, by fixing the water passage member 50 to the fixing portion 35, it can be easily attached to the toilet main body 20.

The fixing part 35 is a through hole that penetrates the upper surface part 28. According to this configuration, the fixing portion 35 can be easily formed on the upper surface portion 28 of the toilet main body 20.

The water-permeable member 50 has a first rib 57 that is inserted into the fixing portion 35. With this configuration, the water-permeable member 50 can be fixed simply by inserting the first rib 57 into the fixing portion 35, so the fixing work of the water-permeable member 50 can be easily performed.

The fixed portion 35 is provided upstream of the outlet 52 at the downstream end of the water-passing member 50. With this configuration, cleaning water is less likely to flow out of the fixed portion 35, making it unnecessary to use a water-stopping member at the fixed portion 35.

The upper surface portion 28 forms a part of the upper surface of the toilet main body 20. The fixing portion 35 penetrates the upper surface portion 28 in the inner and outer directions. According to this configuration, since the fixing part 35 is open on the upper surface of the toilet main body 20, the fixing part 35 can be maintained from above the toilet main body 20. Since the fixing part 35 can be covered by arranging the functional part on the upper surface part 28, a special product for covering the fixing part 35 can be made unnecessary.
