Next, the pattern paper 36 is torn to the left and right with the slit 41 as a boundary, and the toilet 1 is placed directly on the floor 2. As a result, the toilet 1 is surely placed at the planned installation location of the floor 2. By placing the toilet 1 on the floor 2, the floor flange 7 is simultaneously inserted into the drain outlet cover 5a, and the drain outlet 6 of the toilet 1 is simultaneously inserted into the mouth insertion hole 17 of the annular sealing material 14, At the same time, the tip portions of the shaft portions of the T bolts 24 a and 24 b are inserted into the bolt insertion holes 28 a and 28 b of the toilet 1. In the above, the toilet 1 is placed on the floor 2 using the transport rope 42 in order to prevent the toilet 1 from being damaged by directly holding the toilet 1 by hand. May be placed directly on the floor 2 with the toilet in hand.

  After the toilet 1 is placed on the floor 2, the nut 29 is screwed into the male threaded portion protruding upward from the bolt insertion holes 28a, 28b of the T bolts 24a, 24b, and the toilet 1 and the floor flange 7 are fastened. At the same time, the screw 32 is inserted into the screw insertion hole 31 of the toilet 1 and the tip of the screw 32 is fixed to the prepared hole formed in the floor 2. Thus, the construction of the toilet 1 is completed. The construction of the toilet 1 is not limited to the above.

  Here, when the toilet 1 is placed on the floor 2, a state in which the drain port 6 of the toilet 1 is inserted into the mouth insertion hole 17 of the annular seal member 14 is shown in FIG. 6. As shown in the figure, when the toilet 1 is moved downward and brought closer to the floor 2, the guide rib 26 comes into contact with the guided surface 35 and the drain port portion 6 is in plan view with the center thereof being the center of the drain tube portion 8. The toilet bowl 1 is guided so that it may become an overlapping position. That is, when the drain port 6 of the toilet 1 is inserted into the port insertion hole 17, the center of the drain cylinder 8 of the floor flange 7 and the center of the drain port 6 of the toilet 1 in plan view are shifted. The guide rib 26 of the floor flange 7 abuts on the guided surface 35 of the toilet 1 and the movement of the toilet 1 in the horizontal direction is restricted. Thus, when the toilet 1 is placed on the floor 2, the center of the drain port 6 of the toilet 1 and the center of the drain cylinder 8 of the floor flange 7 are completely coincided with each other in a plan view. In the worst case, the drain port 6 is inserted into the port insertion hole 17 in the state shown in FIG. 7 in which the deviation L between the center of the drain tube 8 and the center of the drain port 6 is small. The outer surface of the drain port 6 of the toilet 1 is elastically contacted with an equal force over the entire circumference, and can be evenly sealed over the entire outer surface of the drain port 6. As shown in the conventional example, it is possible to prevent the gap between the drain port portion 6 and the drain tube portion 8 from being generated and a portion that cannot be completely sealed by the annular seal member 14 from being formed. Odor leakage can be reliably prevented by the annular sealing material 14. Further, when the drainage port 6 of the toilet 1 is inserted into the mouth insertion hole 17 in this way, the drainage port 6 is overlapped with the position where the center overlaps the center of the drainage cylinder 8 in a plan view by the guide rib 26. Since it can guide, the toilet 1 can be reliably installed in the planned installation location, and the construction of the toilet 1 is further facilitated.

  Further, particularly in the present embodiment, the guide rib 26 includes the left front guide rib 26a, the left rear guide rib 26b, the left left guide rib 26c, the right front guide rib 26d, the right rear guide rib 26e, and the right right guide rib 26f described above, and is guided. The surface 35 includes the left front guided surface 35a, the left rear guided surface 35b, the left left guided surface 35c, the right front guided surface 35d, the right rear guided surface 35e, and the right right guided surface 35f. When inserting the drain port 6 of the toilet 1 into the port insertion hole 17 of the annular seal member 14, the tapered surface 27a of the left front guide rib 26a, the tapered surface 27b of the left rear guide rib 26b, and the right front guide rib Each of the tapered surface 27d of 26d and the tapered surface 27e of the right rear guide rib 26e has a left front guided surface 35a, The side rear guided surface 35b, the right front guided surface 35d, and the right rear guided surface 35e are brought into contact with each other to regulate the position of the toilet 1 in the front-rear direction, and the left left guide rib 26c is tapered. 27c and the taper surface 27f of the right-hand right guide rib 26f are in contact with the left-hand left guided surface 35c and the right-hand right-guided surface 35f, respectively, so that the lateral movement of the toilet 1 can be regulated and guided. Therefore, the drain port portion 6 of the toilet 1 can be accurately guided with a simple configuration.

  Further, since the guide rib 26 is provided integrally with the fixing ribs 20a and 20b, the strength of the guide rib 26 itself is high, so that the guide rib 26 is damaged when the guide rib 26 strongly hits the guided surface 35. In addition, the floor flange 7 can have a simple shape, and the mold cost of the floor flange 7 can be reduced. Further, since the guide ribs 26 are provided integrally with the fixing ribs 20a and 20b, both the fixing ribs 20a and 20b can be disposed at a position close to the drain tube portion 8, and the drain port cover integrally provided with the drain port 6 is provided. The drain outlet cover 5a and the floor flange 7 can be fixed at a position close to the drain outlet 6 side of 5a, whereby the toilet 1 and the floor flange 7 can be firmly fixed, and the guide ribs 26 of the annular sealing material 14 can be fixed. It can be disposed at a position close to the mouth insertion hole 17, and the toilet 1 can be guided to a more accurate position by the guide rib 26.

  Further, the left rear guide rib 26b, the left left guide rib 26c, the right rear guide rib 26e, and the right right guide rib 26f protrude upward from the drain tube portion 8, and the left rear guided surface 35b, the left left guided surface 35c, and the right side Since the rear guided surface 35e and the right and right guided surface 35f extend below the lower end of the drain port 6, the drain port 6 of the toilet 1 is inserted into the port insertion hole 17 of the annular seal member 14. In this case, before the drain port portion 6 of the toilet bowl 1 is inserted into the drain tube portion 8 of the floor flange 7, the guide rib 26 may guide the drain port portion 6 to be inserted into the drain tube portion 8. In addition, the drain port portion 6 can be easily inserted into the drain tube portion 8.

  Further, since the left left guide rib 26c and the right right guide rib 26f are arranged on a straight line passing through the center of the drainage cylinder portion 8 in plan view, when the floor flange 7 is installed on the floor 2, the left left guide rib 26c. The direction of the floor flange 7 can be adjusted by looking at the right and right guide ribs 26f, and when the pattern 36 is used for the construction of the toilet 1 as in the present embodiment, the left left guide rib 26c and the right right guide rib 26f, the orientation of the floor flange 7 with respect to the pattern 36 can be adjusted, and when the toilet 1 is constructed without using the pattern 36, it is in an easily visible position on the outer side in the left-right direction with respect to the drainage cylinder portion 8. The center position of the drainage cylinder portion 8 can be confirmed by looking at the left left guide rib 26c and the right right guide rib 26f, and the toilet 1 can be easily placed on the floor 2.
