Description

  The present invention relates to a structure for fixing a flush toilet provided with a skirt portion to a floor surface.

  Conventionally, as a fixing structure of a flush toilet equipped with a skirt part, a through hole is made in the skirt part and a screw is penetrated from the outside to the fixing piece fixed to the floor inside the skirt part and screwed into the fixing piece. It is fixed. (For example, see Patent Document 1)

  In the case of the said patent document 1, although a cosmetic cap is set to the head of a screw on the outer peripheral surface of a flush toilet bowl, a cosmetic cap is exposed to the toilet outer surface. In particular, when a separate cosmetic cap is arranged at the front part of the toilet body, there is a problem that it is easy for the user to see and the appearance is poor.

  In addition, in a conventional flush toilet fixing structure having a double-walled skirt with an outer wall and an inner wall, a male fixed to the inner wall of the flush toilet is used to conceal the cosmetic cap at the front of the toilet body. A fitting portion is configured such that the member and the female member fixed to the floor fit in shape, and the flush toilet is fixed by fitting the male member and the female member. (For example, see Patent Document 2)

  In the case of the above-mentioned Patent Document 2, the relative displacement between the male member and the female member, for example, the male member is fixed to the inner wall of the flush toilet, but the assembly variation at that time and the inclination of the fixed surface of the inner wall are fixed. Variation, and the female member is fixed to the floor surface, but if relative displacement such as variation in the fixing position on the floor surface occurs, there is a possibility that the male member and the female member cannot be fitted with water. There was a problem that the toilet bowl could not be fixed to the floor.
