In this publication, a T-shaped fixed fixing plate is arranged at the end of the bolt between the flange of the drainage socket and the mounting surface, and this fixing plate is fixed to the mounting surface together with the flange by wood screws. At the same time, the bolt is projected from the flange portion and inserted into the mounting hole of the base of the toilet bowl, and the toilet bowl is fixed to the drain socket by tightening with a nut from the front surface side of the seat bowl.

[0003]

When the bolt having the T-shaped fixing plate fixed to the end is used in the one disclosed in this publication, the drain socket is hidden by the pedestal of the toilet when fixing the toilet, Since it is not possible to support the bolt, it is to prevent the bolt from turning even if it is not supported. However, when adopting such a structure, a fixing plate at the end is a T-shape. Since it is necessary to specially manufacture bolts that are fixed in a fixed shape, the manufacturing cost is high, and when a different length of bolt is needed due to the difference in the type of toilet bowl, it is inconvenient to recreate it with another specification. There is. In addition, the bolt is fixed to the mounting surface such as the floor with a wood screw and cannot be moved at all, so that the installation direction of the toilet cannot be finely adjusted when the toilet is installed. The present invention has been made in view of the above problems of the prior art, and the purpose thereof is to make it possible to use commercially available bolts, to reduce costs and to use bolts of different lengths. The goal is to be able to easily respond when needed. In addition to the above object, the present invention is a toilet bowl installation structure in which a toilet bowl mounting bolt is fixed to the floor so that stress is not applied to the flange portion when tightening the nut, but the toilet bowl is installed when the toilet bowl is installed. It also aims to enable fine adjustment of the direction.
