Abstract
In order to control the rotational torque of opening/closing bodies, such as seats and lids for Western-styled lavatory stool, allowing them to be easily opened, stopped and held stably in an opened state, and preventing them from dropping abruptly when they are closed, the present invention provides an opening/closing device with a pair of brackets fitted on two sides at the upper end of the rear part of a lavatory stool and a pair of cases, one for each of the pair of brackets, for bearing and holding one side of a corresponding bracket. A holder housing receives each of these cases, and has a fitting part for a lavatory lid, and is disposed rotatably between the pair of brackets. A pair of supporting members for the lavatory is positioned outside the brackets, and is borne and held by the cases. A rotating shaft with a rotation controller is provided within each case, one of these rotating shafts being disposed so as to rotate together with the holder and the other being disposed so as to rotate together with the supporting members.
