BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, the toilet bowl is a flush toilet bowl, and it can be applied to either a wall-mounted type or a floor-standing type. FIG. 1 is a sectional view showing an embodiment of the present invention, which is a floor-standing flush toilet bowl. The cleaning mechanism of the flush toilet 1 shown in FIG. 1 is as follows. Water is supplied to the water supply port 13 from a water supply device such as a low tank or a flash valve (both not shown), and the wash water passes through the trap 2 through the water guide path 12 and is drained as waste water by the drainage port 25. The trap 2 of the flush toilet 1 goes from the drainage outlet 21 of the bowl 11 to the front of the bowl,
It is configured so that it rises up to the height of the middle, reaches the highest part 22, and then is lowered and bent to communicate with the drainage port 25.

The cleaning port 3 is installed on the downstream side of the highest part 22 of the trap, and is for finding and collecting a place such as a foreign substance stuck in the trap 2 from the front of the toilet bowl. The position of the cleaning port 3 is not limited to the front side of the toilet bowl as shown in the embodiment, and may be the side surface or the back surface of the toilet bowl as long as it is in communication with the trap 2. Further, the trap 2 is not limited to the embodiment. Since the cleaning port 3 is provided on the downstream side of the highest portion 22 of the trap 2, the water reservoir RF of the toilet does not reach the position where the cleaning port 3 is present when the toilet is not cleaned. Therefore, even if the cleaning port lid 4 is opened during non-cleaning, there is no risk that the stored water RF will flow out from the cleaning port 3 and stain the floor surface or the like.

FIG. 2 is a side sectional view of the cleaning port lid 4, and FIG.
FIG. 4 is a front view of the cleaning lid 4. The cleaning lid 4 includes a cap 43, a packing 5, a stopper 6, a washer 9, and a screw 71. The cap 43 has a substantially bowl shape, and has a recess 4 formed in the center and a hole 4 for inserting the screw 71.

The insertion portion 51 is integrally formed in a bag shape. A bellows portion 54 is provided in the middle of the connecting portion 57. The insertion portion 51 into which the stopper 6 is inserted is larger in the inside than the long side of the stopper 6, and the outer edge of the seal portion 52, which abuts on the sealing surface 32 of the cleaning opening 3, projects in the circumferential direction. The part 53 is formed. The inner surface of the trap 23 attached to the cleaning port 3
Projections 56 are integrally provided at four places on the contact portion 55 that comes into contact with.

FIG. 6 is a side sectional view of the stopper 6, and FIG.
Is a front view of the fastener 6, FIG. 8 is a front view of the bending member 61, FIG. 9A is a front view of the nut 65, and FIG.
FIG. 6 is a side sectional view of a nut 65. The stopper 6 has a longer side longer than the inner diameter of the cleaning port 3 and a bending member 61 in which the central portion 63 is bent and protruded, and a longer side has a bending member 6
The reinforcing member 62 having substantially the same length as that of 1 is integrated by a method such as welding. Further, a hexagonal hole 631 is formed in the center of the bending member 61. The nut 65 has a slightly smaller outer circumference than the hexagonal hole 631, and the outer circumference 651 is spaced at a distance larger than the thickness of the bending member 61.
A groove portion 652 is formed at a position perpendicular to the axial direction of the nut 65. The nut 65 is inserted into the hexagonal hole 631 of the bending member 61 of the stopper 6, and the bending member 61
The E-shaped retaining ring 66 holds the bending member 61 in the groove 652 of the nut 65 so as to sandwich the bending member 61 from the front and back.
The interval between the E-shaped retaining rings 66 holding the nut 65 is larger than the wall thickness of the bending member 61, and the outer circumference of the nut 65 is slightly smaller than the hexagonal hole 631 of the bending member 61. Although the rotation with respect to the hole 631 is restricted, the nut 65 can be inclined with respect to the bending member 61 at a certain inclination angle α as shown in FIG. 6. Further, since the surface 67 that is inserted into the insertion portion 51 of the packing 5 and comes into contact with the packing 5 is chamfered and the coating 68 of soft vinyl chloride or the like is applied, even if the fastener 6 is tightened, the packing 5 It is designed not to hurt.

The cleaning port lid 4 is attached to the cleaning port 3 as follows. The stopper 5 is fitted into the insertion portion 51 of the packing 5, and the insertion portion 51 is inserted from the cleaning port 3 in a state where the packing 5 and the stopper 6 are integrated. At this time, since the packing 5 is formed with the bellows portion 54, the insertion portion 51 can be tilted obliquely, so that the insertion is easy. Since the length on the long side of the stopper 6 is larger than the inner diameter of the cleaning port 3, the packing 5 can be hooked on the inner surface 23 of the toilet trap. Next, the sealing portion 52 of the packing 5 is brought into contact with the sealing surface 32 of the cleaning port 3, the cap 43 is covered over the packing 5, and the hole 42 opened at the center of the lid main body through the washer 9. The screw 71 is passed through and fastened to the screw portion 64 of the fastener 6.

The stopper 6 is a central portion 63 of the bending member.
Since it has a bent shape, the distance from the cap 43 is short, and the screw 71 and the screw portion 64 can be easily fastened.
In addition, by integrally forming the bending member 61 and the reinforcing member 62, the strength of the fastener 6 itself is reinforced against the fastening of the screw. Since the threaded portion 64 of the stopper 6 is formed by attaching the nut 65, which is separate from the bending member 61, so as to be tiltable to some extent in the tilt direction, the inner surface 23 of the toilet trap 23
Even when the stopper metal contact surface 24 and the sealing surface 32 of the cleaning opening 3 are inclined, the screw 71 can be smoothly fastened to the nut 65, and it is possible to absorb the manufacturing error of the toilet bowl.

Further, the outer peripheral portion of the seal portion 52 of the packing 5 is formed with a convex portion 53 in the circumferential direction. This is a convex portion rather than abutting the sealing surface 32 of the cleaning port 3 with a flat portion. 5
This is because abutting at 3 makes it possible to more reliably seal even with a small screw tightening torque. Further, a protrusion 56 is provided on the contact portion 55 of the packing 5 with the inner surface of the trap. As a result, even when the screw 71 is tightened and the packing 5 is pressed against the inner surface 23 of the toilet trap, the protrusion 56 is first deformed, so that the contact portion 5 with the stopper 6 is deformed.
It is possible to prevent excessive force from being applied to 5.

In the method of fixing the cleaning port lid 4 to the cleaning port 3, the fastening portion between the stopper 6 of the cleaning port lid 4 and the screw 71 is inside the trap 2 of the toilet bowl, so that the cleaning port 3 itself is more than the conventional example. It is possible to reduce the generation amount L of. Further, even if there is a fastening member inside the trap 2 of the toilet bowl, the fastener 6 as the fastening member and the screw 71 are housed in the bag structure of the packing 5 so that the wastewater in the toilet trap 2 is directly contacted. It is possible to suppress the corrosion of the fastening member because it does not exist. Further, the bellows portion 54 provided on the packing 5 facilitates the attachment / detachment work of the cleaning port lid. Further, since the fixing is required only at one point in the central portion of the toilet cleaning lid, the opening / closing operation of the cleaning lid can be simplified.
