  In recent years, with the increasing demand for refurbishment of toilet facilities, there has been a conspicuous case where only the toilet flushing device is replaced with a new model. On the other hand, the toilet bowl automatic cleaning device tends to be downsized in order to emphasize design.

  However, in the conventional toilet automatic cleaning device mounting structure, if a toilet automatic cleaning device having a smaller size than the conventional one is attached, there is a problem that the screw hole traces on the wall are visible and the appearance is impaired.

  Also, in the conventional toilet flushing device, the valve unit is connected to the water supply pipe and the washing pipe, and then the mounting board is fixed to the wall with screws and finally the cover is put on. When it is extremely smaller than the reference value, the cleaning pipe and the cover interfere with each other and it is difficult to carry out the construction. On the other hand, when it is extremely larger than the reference value, there is a problem that there is a gap between the mounting substrate and the wall.

In addition, when the cleaning tube and cover are installed so as not to interfere with each other, there is a slight gap between the toilet bowl automatic cleaning device mounting board and the wall. There were also problems such as difficulty and poor cleanability.
