The problem was that I couldn't do it.

(Means for solving the problem) The present invention was devised in view of the above-mentioned conventional problems, and when attaching the toilet seat to the toilet body,
The purpose is to provide a toilet seat mounting structure that allows all work to be done from above and that also allows the installation position of the toilet seat to be adjusted to an appropriate position. comprising a plug that is installed from above, and a bolt that is inserted from above through a washer into a mounting bolt hole of the toilet seat that is aligned with the bolt hole and whose lower end is connected to the plug and has a considerably smaller diameter than the mounting bolt hole, The bolt hole is formed with hole step portions each having an enlarged diameter at its upper and lower portions, and the plug has a hole step portion formed in the upper hole step portion when the cylindrical portion is inserted into the bolt hole. A head that abuts and locks on the bottom surface, a pair of slide grooves formed in the vertical direction on the side surface of the cylindrical part, and a shaft that is inserted into the cylindrical part about a pivot that is vertically movably inserted into the slide groove. A rectangular block-shaped nut is provided, which is rotatable from a vertical state in which it is housed to a horizontal state in which it is disposed in the lower hole step, and whose longitudinal dimension is larger than the bolt hole;
The nut is formed with an inclined part that guides the nut horizontally when the lower end of the mounting bolt comes into contact with the upper end in the vertical state and is pressed downward, and the central part of the upper surface in the horizontal state is formed with an inclined part that guides the nut in the horizontal direction when the nut is pressed downward. A screw hole is formed into which the lower end of the mounting bolt is screwed.

(Function) A plug is inserted into the bolt hole formed in the toilet body from above, and the plug is locked in the upper step of the bolt hole, and this plug has a rotatable block-shaped nut. Therefore, when inserting the plug, the nut can be stored in the cylindrical part of the plug, and the plug can be easily inserted into the bolt hole of the toilet bowl body from above. After this insertion, the toilet seat can be inserted from above. By inserting the mounting bolt from above into the bolt hole drilled in this toilet seat and pressing the mounting bolt from above,
The lower end of the mounting bolt comes into contact with the nut, and the nut rotates due to the pressing force of the mounting bolt, so that the nut is placed in the lower hole step of the bolt hole of the toilet main body. In this state, the toilet seat is tightened and fixed to the toilet body by screwing the mounting bolt into the nut and tightening it. Therefore, the insertion of the plug, the insertion of the mounting bolts, and the tightening of the mounting bolts can all be performed from above, making it extremely easy to attach the toilet seat to the toilet main body. Furthermore, since the plug is installed separately in the bolt hole of the toilet bowl body, and only the mounting bolt is inserted into the bolt hole of the toilet seat,
The toilet seat can be moved from the toilet main body through the bolt hole, and even if there is an error in the position of the bolt hole in the toilet main body, the toilet seat can be attached to the proper position with respect to the toilet main body.
