ABSTRACT:
An opening-closing device for a Western style toilet seat and seat cover is disclosed, in which a pair of hinge cases are mounted at a predetermined spacing at the rear upper end of a Western style toilet bowl; in either of the pair of hinge cases a rotating shaft for the seat and a rotating shaft for the seat cover are rotatably mounted; on the rotating shaft for the seat in either hinge case, the seat mounting section is rotatably mounted, and on the rotating shaft for the seat cover in the hinge case, the seat cover mounting section is rotatably mounted; and a rotation control mechanism is mounted on the rotating shaft for the seat and the rotating shaft for the seat cover, to thereby prevent sudden drop of the seat and seat cover, At this time, the rotation control mechanism may be a cam mechanism using a compression spring, a torsion spring, a rotation camper, or a friction mechanism. Furthermore, the cam mechanism may be comprised of a stationary cam fixed on a partition wall provided in the hinge case with the rotating shaft inserted in the center, a rotating-sliding cam which is disposed oppositely to the stationary cam and can slide in the axial direction of the rotating shaft while rotating together with the rotating shaft, and a compression spring for pressing the rotating-sliding cam towards the stationary cam side.
