<p>A mechanism for supporting toilet bowl covering members, comprises a cylinder (5) fixedly mounted on a toilet body and rotatably supporting a toilet seat (2) or a toilet lid (3), lock plates (7, 8) fitted within the cylinder and connected for rotation with the toilet seat (2) or the toilet lid (3), and a plurality of sliding rings (10a to 10f and 10A to 10F) fitted around the lock plates and held in sliding contact with the inner peripheral surface of the cylinder (5) and having respective arcuate recesses (13) of gradually variable arcuate lengths for controlling rotation of said lock plates (7, 8). When the toilet seat (2) or the toilet lid (3) is rotated to close the toilet body, the lock plates (7, 8) are also rotated to successively come into contact with steps (11) in the recesses (13). As a result, the sliding rings (10a to 10f and 10A to 10F) are successively pressed against the inner peripheral surface of the cylinder (5) so that the member closes slowly.</p> |
