A seal is formed between the upper edge and the rim _a3 .

As shown in FIG. 4, the recess 2 formed between the seal member 1 and the outer peripheral surface of the ball part b ₁ and the inner surface of the rim a ₃ is filled with a silicone sealing material 3 to make the surface smooth. , it may be made easier to clean.

Further, a scattering prevention cover 4 is sandwiched between the front side portion of the sealing member 1 and the outer peripheral surface of the ball portion _b1 .

The scattering prevention cover 4 is formed into a substantially U-shape in plan by bending the left and right side edges of a flat plate molded from rubber or synthetic resin, _etc. The removed portion hangs down to the front side of the opening at the lower end of the ball part _b1 .

Therefore, in the case of men's urinals, the user discharges urine from a high position toward the front cover of the Japanese-style toilet, so the dirty water that bounces off the bottom of the saucer is splashed onto the front cover _A2 side. Although it is easy to scatter, the above-mentioned anti-scattering cover 4 prevents the waste water from scattering to the front cover part _a2 side.

Further, if a plurality of notches 5 are provided at appropriate intervals on the lower end of the scattering prevention cover 4 to form a curtain shape, cleaning is easy even if the inner surface of the front cover part _a2 becomes dirty.

Although not shown in the drawings, the scattering prevention cover 4 may be formed integrally with the sealing member 1, or may be formed over the entire circumference of the sealing member 1.

In addition, a mounting hole b ₄ is bored in the middle upper wall of the seat body B, which _is located inside the ball part b ₁ and passes through the upper wall vertically. A mounting screw 8 for rotatably mounting the lid 7 is inserted as necessary, and a nut 9 is tightened and fixed to the tip of the screw 8 from the inner surface of the seat body B.

Therefore, the nut 9 that tightens the mounting screw 8 can be reached by hand or a tool from inside the ball part b ₁ , so that the toilet seat 6 and the lid 7 can be easily attached and detached.

On the other hand, _a rim passageway b5 is provided at the upper opening edge of the ball part _b1 over the entire circumference, and the rim passageway _b5 is formed to protrude inward so as to face into the ball part _b1 , A large number of water injection holes b ₆ are bored at appropriate intervals on the lower surface thereof, and a water supply pipe c ₃ communicating with the water supply device C is connected to an appropriate location of the water passage b ₅ .

The water supply device C is a water supply source that supplies water to the so-called flush type Japanese-style toilet A, such as a water storage tank or a flush valve. A branch pipe c ₂ is connected to the tip of the pipe c ₁ , and one end of the branch pipe c ₂ is
A water supply pipe _c3 communicating with the rim water passage _b4 is connected, and a water supply pipe _c4 communicating with the Japanese style toilet A is connected to the other end.

The Japanese-style toilet A shown in the drawing is of the so-called flushing type, and has a water supply chamber _C4 at the front end into which a water pipe _C4 is inserted, and the flushing water supplied from the water supply device C to the water supply chamber _C4 . A part of the water is poured into the toilet bowl A from above the room _C4 .
The remaining washing water is introduced into the front cover part A ₂ to wash the inner surface of the front cover part A ₂ , and the remaining washing water is passed through the communication hole A ₅ drilled on the bottom surface of the water supply chamber A ₄ to the water channel A ₆ to the rear end of the toilet bowl A. Formed blowhole a ₇
The waste excreted on the saucer part _A1 by being ejected from the hole _A7 is discharged to the drain part _A8 , and the waste is discharged from the waterway.
The water flows from the middle of _A6 through the rim communication hole _A9 of toilet A to the rim water injection hole _A10 , and the inside of bowl _A11 of toilet A is cleaned.

Next, there is shown in FIG. 5 or another embodiment of the present invention, in which a seal member 1 is provided between the rear half of the outer peripheral surface of the ball part b ₁ and the rear half of the rim a ₃ , Shatterproof cover 4 tightened together with mounting screw 8
By extending the rear end rearward and coming into contact with the front end surface of the sealing member 1, the space between the outer circumferential surface of the ball part b ₁ and the rim a ₃ which is the upper edge of the saucer part a ₁ is hermetically sealed. It is something.

In both of the above embodiments, a type in which the Japanese-style toilet bowl A is provided on a stepped floor surface D is shown, but the present invention is not limited to this, and a type in which the Japanese-style toilet bowl A is provided on a flat floor surface is not limited to this. Needless to say, the Japanese style toilet A is not limited to the flush type, but may be of other types. Further, although the water supply to the stool body B is branched from the secondary side of the water supply device C, the present invention is not limited to this, and water may be supplied in any manner, such as providing a separate water supply device exclusively for the stool body B.

Since the present invention has the above configuration, it has the following advantages.

A sealing member is interposed between the outer circumferential surface of the ball part and the upper edge of the saucer part of the Japanese-style toilet near the outer circumferential surface to form an airtight seal between the two, so that sewage and filth splashed on the saucer part of the Japanese-style toilet are prevented. It does not adhere to areas that are difficult to clean, such as the upper surface of the rim of a Japanese-style toilet bowl or the inner surface of the body of the toilet bowl, and the dirty areas are around the sealing member and can be easily cleaned from above with a brush or the like.

Therefore, the lock is easy to clean even if the seat body is not easily removable, such as when the entire seat body is made of ceramic or when the water supply pipe connected to the seat body is made of metal. It can be cleaned and kept clean, and sewage and filth do not accumulate and create odors unlike conventional products.
