2. Description of the Related Art Conventionally, there is a toilet disclosed in Japanese Utility Model Publication No. 6-34455 as a toilet that can be used for both simple flushing and main flushing. This can be switched between simple flushing and main flushing by changing the member connected to the outlet at the bottom of the bowl of the toilet bowl. That is, by connecting the valve unit to the outlet, it can be used for simple flushing, and by connecting the trap member to the outlet, it can be used for main flushing.

[0003]

When switching from simple flushing to main flushing, the valve unit is removed and the trap member is connected to the discharge port. In this case, the seal between the discharge port and the trap member is simple and easy. It must be done reliably. By the way, butyl rubber alone is often used as a sealing member for sealing between a porcelain and the like having a pottery surface. However, since butyl rubber alone is soft and easily deformed, there is a problem that it is difficult to perform on-site work.

The present invention has been made in view of the above description, and when a trap member is attached to switch from simple flushing to main flushing, sealing between the discharge port and the trap member can be easily and reliably performed. The task is to be able to do so.
