Description

  The present invention relates to a flush toilet device, and in particular, to a drainage channel extending from an inner bowl portion, a case body in which a trap portion in which a rear end that is turned upside down as a free end communicates with an external drainage pipe is accommodated. The present invention relates to a flush toilet apparatus having a flush toilet bowl disposed.

  As a flush toilet device as described above, conventionally, for example, as disclosed in Japanese Patent Application Laid-Open No. 2002-173971, the drainage channel 2 extending from the inner bowl portion 1 as shown in FIG. A flush toilet 4 having a case main body 6 in which a trap portion 3 having a rear end rotating in reverse and communicating with an external drain pipe 5 is accommodated therein is formed integrally with a lower opening of the flush toilet 4 The case body 6 is joined and fixed to the attached mounting portion 41 via a flange 61 integrally formed, and the flange 61 is fixed to the flange 51 of the external drain pipe 5 of the flush toilet 4. It has been known.

  In this type of flush toilet apparatus, it is one of the important elements to secure and fix the water tightness by closely contacting the flange portion 61 formed integrally with the case body 6 with the flange 51 of the external drain pipe 5. Therefore, as shown in FIG. 4, the collar 61 has a configuration in which the rubber packing 7 is placed on the flange 51 of the external drain pipe 5 of the flush toilet 4 and is fixed by using bolts or the like. It has been adopted.

  However, in this configuration, when the flange portion 61 integrally formed with the case body 6 is joined and fixed to the mounting portion 41 of the ceramic flush toilet 4 in which the lower opening is distorted when firing, as shown in FIG. As shown in the figure, when the flush toilet 4 is fixed to the floor plane F so as not to rattle, the flatness due to the distortion of the mounting portion 41 that is provided around the opening of the flush toilet 4 is integrally formed. The part 61 will also become familiar and warp. For this reason, it is assumed that the water-tightness is not sufficient, and there is a concern that the drainage of water and odor leak may occur depending on the construction state.

Therefore, for example, it is conceivable to increase the thickness of the rubber packing 7 to the extent that strain absorption generated in the attachment portion 41 of the flush toilet 4 can be absorbed. However, changing the thickness of the rubber packing 7 causes a new work variation in the bolt tightening work which is a fixing tool for bringing the flange 61 of the case body 6 into close contact with the flange 51 of the external drain pipe 5. It is expected to bring about the problem. This is because the bolt tightening amount increases.
