[0013] The following describes the fixing structure of the branch part 8. The fixing structure of the branch part 8 is a structure for fixing the branch part 8 (fixed part) to the base plate 5 (fixed part) arranged inside the toilet device 1.

[0014] In describing the fixing structure of the branch part 8 of this embodiment, the direction along the front-rear direction of the toilet device 1 is referred to as the front-rear direction Y of the branch part 8. In the front-rear direction Y, the front side is referred to as the front side Y1, and the rear side is referred to as the rear side Y2. The direction along the left-right direction of the toilet device 1 is referred to as the left-right direction X of the branch part 8. In the left-right direction X, one side is referred to as one side X1 (the right rear side in Figure 2, the right side in Figures 3 to 6), and the other side is referred to as the other side X2 (the left front side in Figure 2, the left side in Figures 3 to 6). The direction along the up-down direction of the toilet device 1 is referred to as the up-down direction of the branch part 8.

[0015] The structure of the branch part 8 fixed to the base plate 5 will be described. As shown in FIGS. 3 to 6, the branch part 8 has a main body 80, a first mounting piece 81, a second mounting piece 82, and a third mounting piece 83. As shown in FIG. 6, the main body 80 has a lower inlet pipe 80a formed at the bottom and extending in the vertical direction, an upper branch pipe 80b extending upward from the upper end of the lower inlet pipe 80a, and a side branch pipe 80c extending laterally on the front side Y1 from midway in the vertical direction of the upper branch pipe 80b. The branch part 8 is attached to the base plate 5 with the lower inlet pipe 80a inserted into the through-hole 5a of the base plate 5.

[0016] The first mounting piece 81, the second mounting piece 82, and the third mounting piece 83 are formed to protrude laterally from the lower introduction pipe 80a. When the branching part 8 is fixed to the base plate 5, the first mounting piece 81, the second mounting piece 82, and the third mounting piece 83 are arranged at the upper end of a wall part 502 that rises from the bottom plate 501 of the base plate 5.

[0017] 6, the wall portion 502 is formed around the through-hole 5a of the base plate 5 into which the main body 80 of the branching component 8 is inserted. The wall portion 502 has an arc wall portion 502a formed on the front side Y1 in the front-rear direction Y, and a rear extending wall portion 502b arranged on the rear side Y2 of the end portion of the arc wall portion 502a on one side X1 in the left-right direction X.

[0018] The first mounting piece 81 protrudes from a front side Y1 in the front-rear direction Y of the lower introduction pipe 80a to the other side X2 in the left-right direction X. A U-shaped first branch component side U-shaped screw hole 811 (first fixed component side U-shaped screw hole) is formed in the first mounting piece 81. The second mounting piece 82 protrudes from a front side Y1 in the front-rear direction Y of the lower introduction pipe 80a to one side X1 in the left-right direction X. A U-shaped second branch component side U-shaped screw hole 821 (second fixed component side U-shaped screw hole) is formed in the second mounting piece 82. The third mounting piece 83 protrudes from a rear side Y2 in the front-rear direction Y of the lower introduction pipe 80a to one side X1 in the left-right direction X. A U-shaped third branch component side U-shaped screw hole 831 (third fixed component side U-shaped screw hole) is formed in the third mounting piece 83.

[0019] As shown in FIGS. 3 and 4, the branch component 8 is fixed to the base plate 5 by a first fixing structure 11, a second fixing structure 12, and a third fixing structure 13.

[0020] The following describes the first fixing structure 11. In the first fixing structure 11, as shown in Figures 3 and 4, the branch part 8 is fixed to the base plate 5 by a first screw 801 (first fastening member).

[0021] 3 and 4, in the first fixing structure 11, the branch component 8 is arranged on one side X1 in the left-right direction X of a front side Y1 of the branch component 8, with a gap S1 provided between it and the first plate-side restricting portion 511 of the base plate 5. As shown in FIGS. 5 and 6, the branch component 8 has a U-shaped first branch component-side U-shaped screw hole 811 (first fixing component-side U-shaped screw hole) formed in the first mounting piece 81. The first branch component-side U-shaped screw hole 811 is arranged on the other side X2 in the left-right direction X of the front side Y1 of the branch component 8, and opens out toward the other side X2 in the left-right direction X.

[0022] As shown in Figures 5 and 6, the base plate 5 has a first plate side regulating portion 511 (first regulating portion), a first plate side screw hole 512 (first fixed component side screw hole), and a first screw slippage prevention rib 513.

[0023] 3 and 4, the first plate-side restricting portion 511 is disposed at an upper end of the arc-shaped wall portion 502a of the base plate 5 on one side X1 in the left-right direction X of the front side Y1 of the branch component 8. The first plate-side restricting portion 511 restricts the position of the one side X1 in the left-right direction X of the branch component 8. As shown in FIGS. 5 and 6, the first plate-side screw hole 512 is provided at an upper end of the arc-shaped wall portion 502a of the base plate 5 on the other side X2 in the left-right direction X of the front side Y1 of the branch component 8.

[0024] The first screw slippage prevention rib 513 is provided on the other side X2 in the left-right direction X of the first plate-side screw hole 512, around the periphery of the first plate-side screw hole 512 provided at the upper end of the arc wall portion 502a of the base plate 5. As shown in FIG. 5 , the first screw slippage prevention rib 513 is disposed between the tips of the open U-shaped portions of the first branch component-side U-shaped screw hole 811 when the branch component 8 is attached to the base plate 5. The first screw slippage prevention rib 513 guides insertion of the shaft of the first screw 801 into the first branch component-side U-shaped screw hole 811, thereby preventing slippage of the first screw 801 when the first screw 801 is inserted into the first branch component-side U-shaped screw hole 811.

[0025] 5, with the branch component 8 attached to the base plate 5, the first screw 801 is inserted into the first branch component U-shaped screw hole 811 and the first plate screw hole 512 on the other side X2 in the left-right direction X of the branch component 8. As a result, the first screw 801 regulates the position of the other side X2 in the left-right direction X of the branch component 8 at the edge of the first branch component U-shaped screw hole 811.

[0026] In the above-described first fixing structure 11, the branch component 8 is arranged with a gap S1 provided between it and the first plate-side restricting portion 511 of the base plate 5 on one side X1 in the left-right direction X of the front side Y1 of the branch component 8. In this state, on the other side X2 in the left-right direction X of the front side Y1 of the branch component 8, the first screw 801 is inserted into the first branch component-side U-shaped screw hole 811 and the first plate-side screw hole 512 to fix the branch component 8 to the base plate 5. In this way, by providing the gap S1, manufacturing variations in the positions of the screw holes during manufacturing can be absorbed, and the branch component 8 can be fixed to the base plate 5 with the positions of the one side X1 and the other side X2 in the left-right direction X of the branch component 8 restricted.

[0027] The following describes the second fixing structure 12. In the second fixing structure 12, as shown in Figures 3 and 4, the branch part 8 is fixed to the base plate 5 by a second screw 802 (second fastening member).

[0028] 3 and 4, in the second fixing structure 12, the branch component 8 is arranged on the other side X2 in the left-right direction X of the front side Y1 of the branch component 8 with a gap S2 provided between it and the second plate-side restricting portion 521 of the base plate 5. As shown in FIGS. 5 and 6, the branch component 8 has a U-shaped second branch component-side U-shaped screw hole 821 (second fixing component-side U-shaped screw hole) formed in the second mounting piece 82. The second branch component-side U-shaped screw hole 821 is arranged on one side X1 in the left-right direction X of the front side Y1 of the branch component 8 and opens out toward the side of the one side X1 in the left-right direction X.

[0029] As shown in Figures 5 and 6, the base plate 5 has a second plate side regulating portion 521 (second regulating portion), a second plate side screw hole 522 (second fixed component side screw hole), and a second screw slippage prevention rib 523.

[0030] 3 and 4, the second plate-side restricting portion 521 is disposed at the upper end of the arc-shaped wall portion 502a of the base plate 5 on the other side X2 in the left-right direction X of the front side Y1 of the branch component 8. As shown in FIGS. 5 and 6, the second plate-side restricting portion 521 restricts the position of the other side X2 in the left-right direction X of the branch component 8. The second plate-side screw hole 522 is provided at the upper end of the arc-shaped wall portion 502a of the base plate 5 on one side X1 in the left-right direction X of the front side Y1 of the branch component 8.

[0031] The second screw slippage prevention rib 523 is provided on one side X1 in the left-right direction X of the second plate-side screw hole 522, around the periphery of the second plate-side screw hole 522 provided at the upper end of the arc wall portion 502a of the base plate 5. As shown in FIG. 5 , the second screw slippage prevention rib 523 is disposed between the tips of the open U-shaped portions of the second branch component-side U-shaped screw hole 821 when the branch component 8 is attached to the base plate 5. The second screw slippage prevention rib 523 guides insertion of the shaft of the second screw 802 into the second branch component-side U-shaped screw hole 821, thereby preventing slippage of the second screw 802 when the second screw 802 is inserted into the second branch component-side U-shaped screw hole 821.

[0032] 5, with the branch component 8 attached to the base plate 5, the second screw 802 is inserted into the second branch component U-shaped screw hole 821 and the second plate screw hole 522 on one side X1 in the left-right direction X of the branch component 8. As a result, the second screw 802 regulates the position of one side X1 in the left-right direction X of the branch component 8 at the edge of the second branch component U-shaped screw hole 821.

[0033] In the second fixing structure 12 described above, the branch component 8 is arranged with a gap S2 provided between the branch component 8 and the second plate-side restricting portion 521 of the base plate 5 on the other side X2 in the left-right direction X of the front side Y1 of the branch component 8. In this state, the second screw 802 is inserted into the second branch component-side U-shaped screw hole 821 and the second plate-side screw hole 522 on one side X1 in the left-right direction X of the front side Y1 of the branch component 8 to fix the branch component 8 to the base plate 5. In this way, by providing the gap S2, manufacturing variations in the positions of the screw holes during manufacturing can be absorbed, and the branch component 8 can be fixed to the base plate 5 with the positions of the one side X1 and the other side X2 in the left-right direction X of the branch component 8 restricted.

[0034] The following describes the third fixing structure 13. In the third fixing structure 13, the branch component 8 is fixed to the base plate 5 by a third screw 803, as shown in FIGS.

[0035] 5 and 6, in the third fixing structure 13, the branch component 8 has a U-shaped third branch component side U-shaped screw hole 831 (third fixing component side U-shaped screw hole) formed in the third mounting piece 83. The third branch component side U-shaped screw hole 831 is arranged on one side X1 in the left-right direction X on the rear side Y2 of the branch component 8, and opens out toward the one side X1 in the left-right direction.

[0036] 5 and 6, the base plate 5 has a third plate-side screw hole 532 (third fixed component-side screw hole) and a third screw misalignment prevention rib 533. The third plate-side screw hole 532 is provided on the rear side Y2 of the upper end portion of the rearward extending wall portion 502b of the base plate 5.

[0037] The third screw slippage prevention rib 533 is provided on one side X1 in the left-right direction X of the third plate-side screw hole 532, around the periphery of the third plate-side screw hole 532 provided at the upper end of the rearward extending wall portion 502b of the base plate 5. As shown in FIG. 5 , the third screw slippage prevention rib 533 is disposed between the tips of the open U-shaped portions of the third branch component-side U-shaped screw hole 831 when the branch component 8 is attached to the base plate 5. The third screw slippage prevention rib 533 guides insertion of the shaft of the third screw 803 into the third branch component-side U-shaped screw hole 831, thereby preventing slippage of the third screw 803 when the third screw 803 is inserted into the third branch component-side U-shaped screw hole 831.

[0038] 5, with the branch component 8 attached to the base plate 5, the third screw 803 is inserted into the third branch component U-shaped screw hole 831 and the third plate screw hole 532. In this way, the third screw 803 fixes the branch component 8 to the base plate 5.

[0039] By fixing one side X1 in the left-right direction X at the rear side Y2 in the front-to-rear direction Y of the branching part 8 using the above-mentioned third fixing structure 13, the branching part 8 can be fixed to the base plate 5 while preventing the rear side Y2 part of the branching part 8 in the front-to-rear direction Y from floating upward.

[0040] The fixing structure of the toilet apparatus 1 of this embodiment described above provides the following effects.

[0041] In the fixing structure of the toilet device 1 of this embodiment, in the first fixing structure 11, the base plate 5 has a first plate side regulating portion 511 that regulates the position of one side X1 of the branch part 8 in the left-right direction X, and a first plate side screw hole 512 provided on the other side X2 of the branch part 8 in the left-right direction X, and the branch part 8 has a first branch part side U-shaped screw hole 811 that is U-shaped and positioned on the other side X2 of the branch part 8 and opens toward the side, and is equipped with a first screw 801 that is inserted into the first branch part side U-shaped screw hole 811 and the first plate side screw hole 512 when the branch part 8 is attached to the base plate 5, and regulates the position of the other side X2 of the branch part 8 in the left-right direction X. As a result, by providing the first fixing structure 11, the U-shaped screw hole 811 on the first branch component side can absorb manufacturing variations in the position of the screw hole during manufacturing, and the branch component 8 can be fixed to the base plate 5 while regulating the positions of one side X1 and the other side X2 in the left-right direction X of the branch component 8.

[0042] In this embodiment, the branch component 8 is arranged with a gap S1 provided between it and the first plate-side restricting portion 511 on one side X1 in the left-right direction X of the branch component 8. By providing the gap S1 using the first fixing structure 11, manufacturing variations in the positions of the screw holes during manufacturing can be further absorbed.

[0043] In this embodiment, in the second fixing structure 12, the base plate 5 has a second plate side regulating portion 521 that regulates the position of the other side X2 of the branch part 8 in the left-right direction X, and a second plate side screw hole 522 provided on one side X1 of the branch part 8 in the left-right direction X, and the branch part 8 has a U-shaped second branch part side U-shaped screw hole 821 that is arranged on one side X1 of the branch part 8 in the left-right direction X and opens to the side, and is equipped with a second screw 802 that is inserted into the second branch part side U-shaped screw hole 821 and the second plate side screw hole 522 when the branch part 8 is attached to the base plate 5 and regulates the position of one side X1 of the branch part 8 in the left-right direction X.

[0044] Therefore, by providing the second fixing structure 12, the second branch component side U-shaped screw hole 821 can absorb manufacturing variations in the positions of the screw holes during manufacturing, and the branch component 8 can be fixed to the base plate 5 in a state where the positions of one side X1 and the other side X2 in the left-right direction X of the branch component 8 are restricted. Furthermore, by providing the second fixing structure 12 in addition to the first fixing structure 11, the two fixing structures, the first fixing structure 11 and the second fixing structure 12, can absorb manufacturing variations and more firmly fix the branch component 8 to the base plate 5 in a state where the positions of one side X1 and the other side X2 in the left-right direction X are restricted.

[0045] In this embodiment, the branch component 8 is arranged with a gap S2 provided between it and the second plate-side restricting portion 521 on the other side X2 in the left-right direction X of the branch component 8. By providing the second fixing structure 12 in addition to the first fixing structure 11, the gap S2 is provided in addition to the gap S1, which further absorbs manufacturing variations in the positions of the screw holes during manufacturing.

[0046] In this embodiment, the base plate 5 has a first screw misalignment prevention rib 513 that prevents misalignment of the first screw 801. As a result, when the first screw 801 is inserted into the screw hole, the screw misalignment prevention rib 513 guides the first screw 801, thereby preventing the screw from misaligning when the first screw 801 is inserted.

[0047] In this embodiment, the base plate 5 has a second screw misalignment prevention rib 523 that prevents misalignment of the second screw 802. As a result, when the second screw 802 is inserted into the screw hole, the screw misalignment prevention rib 523 guides the second screw 802, thereby preventing the screw from misaligning when the second screw 802 is inserted.

[0048] While the preferred embodiments of the present disclosure have been described above, the present disclosure is not limited to the above-described embodiments and can be modified as appropriate.

[0049] In the above embodiment, the fixed part is configured by the base plate 5, and the fixed part is configured by the branch part 8. However, this is not limited to this. For example, the fixed part may be configured by the cover member 72 of the toilet apparatus 1, and the fixed part may be configured by a fixing part that fixes the cover member 72.

[0050] In the above embodiment, as shown in FIGS. 3 and 4 , in the first fixing structure 11, the branch component 8 is arranged with a gap S1 between it and the first plate-side restricting portion 511 of the base plate 5 on one side X1 in the left-right direction X of the front side Y1 of the branch component 8. In the second fixing structure 12, the branch component 8 is arranged with a gap S2 between it and the second plate-side restricting portion 521 of the base plate 5 on the other side X2 in the left-right direction X of the front side Y1 of the branch component 8. However, this is not limiting. The branch component 8 (fixed component) may be arranged with a gap between it and the base plate 5 (fixed component) on either one side X1 or the other side X2 in the left-right direction X of the branch component 8 (fixed component), rather than on both sides X1 and X2 in the left-right direction X of the branch component 8 (fixed component).
