[0003]

However, in the conventional flush toilet device described above, since the outer peripheral surface of the ball portion and the inner peripheral surface of the upper rim of the Japanese style toilet are sealed by the seal material, the upper surface of the seal material and the seat A gap is created between the body and the seal, and the sealing force escapes upwards, and not only a sufficient sealing force cannot be obtained, but also when the joint of the seal material is unbonded, the seal material itself is removed from the rim surface. Since it escapes, it may not be possible to seal it.

The present invention has been made in view of the above-mentioned problems of the prior art. The purpose of the present invention is to cover the existing flush-type Japanese-style toilet bowl with the stool body mounted and fixed to the stool body. In the flush toilet device in which the ball portion opening faces the inside of the Japanese-style toilet, the sealing force of the sealing material that seals between the ball portion of the stool and the upper edge rim of the Japanese-style toilet does not escape, Furthermore, it is to prevent the sealing force from changing even if the adhesive of the sealing material is removed.

[0005]

In order to achieve the above object, in the flush toilet device of the present invention, the Japanese-style toilet is attached to the outer peripheral portion of the ball portion of the stool body mounted and fixed on the existing flush-type Japanese-style toilet bowl. A sealing material joint is formed in parallel with the upper edge rim upper surface of the toilet bowl, and the sealing material is clamped and fixed between the joint portion and the upper edge rim upper surface of the Japanese style toilet bowl. A sealing material engaging step portion is provided at the sealing material joining portion, and the sealing material is engaged with the step portion to attach the sealing material to the sealing material joining portion. The sealing material engaging stepped portion may be formed in a groove shape so that the sealing material is engaged in a fitting manner. Further, it is desirable that a groove be provided in the sealing material so that the groove is filled with an adhesive.

[0006]

In the flush toilet device configured as described above, the sealing material is pressed vertically against the upper edge rim upper surface of the Japanese style toilet by the sealing material joint portion of the stool, so that the sealing force is not increased. It runs perpendicular to the upper rim top surface of the Japanese style toilet without running away. Moreover, since the sealing material is engaged with the sealing material engaging step portion provided in the sealing material joining portion, the sealing material does not move even if the adhesion by the adhesive or the like is broken.
