Claims

[Scope of utility model registration request]

In an opening/closing mechanism that connects at least one of a toilet seat and a toilet lid to a toilet bowl in an openable/closable manner, the opening/closing mechanism includes:
A mounting shaft is inserted and supported through a mounting seat provided at the base end of at least one of the toilet seat and the toilet lid, and the mounting shaft has a cam part on a part of its circumferential surface, and the mounting shaft corresponds to the cam part. A restraining cap for restraining the rotation of the mounting shaft is integrated into the opening/closing mechanism, and the restraining cap is provided with a restraining piece that is elastically deformed by contacting the circumferential surface of the cam portion, and the restraining piece restrains the mounting shaft from rotating. An opening/closing mechanism for a toilet seat and a toilet lid, characterized in that the toilet seat and the toilet lid can be restrained in their upright positions by rotation regulation.
