An attachment fixing portion 26 is attached to the bottom of the tank device 4, and the attachment fixing portion 26 is fixed to the bottom portion of the tank device 4 by a fastening member 32. A drain packing 34 is disposed on the outer periphery of the drain port 22 of the bottom 20 of the tank device 4. The drainage packing 34 is in a state in which the drainage packing 34 is fitted on the outer periphery of the drainage port portion 22 without being dropped, so that the drainage packing 34 itself is tightened. The fixing bolt 46 hangs downward from the mounting fixing portion 26 with its upper end attached to the mounting fixing portion 26 and its lower end not yet attached.

An installation formed on the front side of the cabinet panel 2 in order for the installer to place the unit of the tank device 4 to which each member has been attached to the state as described above in a state of being hidden in the cabinet panel 2 at the rear of the toilet bowl. The tank device 4 is attached to the fixed pedestal unit from the mouth 2a.
Specifically, as shown in FIGS. 5 to 7, the rib 28 of the mounting fixing portion 26 of the bottom portion 20 of the tank device 4 is placed on the pedestal convex portion 42 c of the connection joint 42 of the tank device fixing pedestal unit 36. As shown by an arrow A1 in FIG. 2, the mounting fixing portion 26 is disposed from the mounting opening 2a formed on the front side of the cabinet panel 2 as shown in FIG. 1 to a predetermined seating position behind the cabinet panel 2. The tank device 4 in the attached state can be slid in the front-rear direction.

  At this time, as shown in FIG. 7, the rib 28 is slid while moving so as to slide backward on the pedestal convex portion 42c. The hanging wall 26e at the rear end of the attachment fixing portion 26 is slid rearward on the connection joint 42. The entire tank device 4 is slid rearward substantially horizontally. The fixing bolt 46 of the mounting fixing portion 26 is slid rearward along the guide port 48. The fixing bolt 46 of the attachment fixing portion 26 can freely move in the front-rear direction along the guide port 48, and is further prevented from moving in the left-right direction by the guide port 48. The installer attaches the tank device 4 to a relatively simple and accurate position while easily recognizing the position of the base convex portion 42c and the rib 28 or the concave portion 26a, or the positions of the fixing bolt 46 and the guide port 48. be able to.

As shown in FIGS. 8 and 9, when the rib 28 is slid on the pedestal convex portion 42c while moving backward, and the pedestal convex portion 42c reaches a position facing the concave portion 26a (predetermined seating position), The wall 26e reaches a position beyond the rear end face 42d of the connection joint 42. When the drooping wall 26e reaches the rear end of the connection joint 42, the drooping wall 26e can be engaged with the rear end surface 42d of the connection joint 42, and the mounting fixing portion 26 can be accurately positioned. Further, it is possible for the builder to easily see from the front side whether or not the pedestal convex part 42c is located at a position facing the concave part 26a, and the bottom part 20 of the tank apparatus 4 is connected to the tank apparatus fixed pedestal unit 36. Can be easily installed.
When the concave portion 26a reaches a position where the concave portion 26a can be lowered to fit into the pedestal convex portion 42c, that is, a predetermined seating position of the bottom portion 20 of the tank device 4, the bottom portion 20 of the tank device 4 can start to descend. .

In FIG. 12, the state in which the rib 28 is slid so as to slide backward on the pedestal convex portion 42c and the concave portion 26a reaches the pedestal convex portion 42c is shown in an enlarged manner.
The rib 28 of the mounting fixing portion 26 protrudes downward from the inner bottom surface 26b of the mounting fixing portion 26 by a length L1. Further, the base convex portion 42 c of the connection joint 42 protrudes upward by a length L 2 from the flat surface 42 b on the upper surface of the connection joint 42. Therefore, the length from the inner bottom surface 26b of the mounting fixing portion 26 to the flat surface 42b of the connection joint 42 is the length of L1 + L2. Here, the drain packing 34 protrudes downward from the inner bottom surface 26b of the mounting fixing portion 26 by a length L3. Furthermore, the drain port portion 22 (fastening member 32) protrudes downward from the inner bottom surface 26b of the attachment fixing portion 26 by a length L4. Here, the length of L3 is shorter than the length of L1 + L2, and the length of L4 is shorter than the length of L1 + L2. Since the fastening member 32 is formed so as to extend slightly below the drain packing 34, the length L4 is longer than the length L3.
Therefore, neither the drainage packing 34 nor the drainage port portion 22 contacts the flat surface 42b of the connection joint 42 while the rib 28 slides on the base convex portion 42c (the concave portion 26a). Accordingly, it is possible to prevent the drainage packing 34 from coming into contact with the flat surface 42b and receiving a lateral force.
