[Prior art]

 Conventionally, a Western-style toilet has a structure on the assumption that the portion on which the toilet seat sits is generally clean when used, and is used. Therefore, the toilet seat surface was not usually cleaned or disinfected after each use. However, since it is a toilet seat, it is unavoidable that it will actually get soiled, and in fact, microscopic examinations have usually found E. coli on its surface. Of course, this is not to the extent that there is a problem with hygiene in the general usage of Western-style toilets, but Western-style toilets used by the public or similar facilities used by an unspecified number of people are used. It goes without saying that, especially in combination with the growing concern about hygiene, it is desired that the toilet seat be provided with more hygienic maintenance. As a measure for this, there was a Western-style toilet with a mechanism that provided a special cover on the toilet seat surface and automatically replaced it to provide a clean toilet seat.
