Abstract
The present invention provides an opening-and-closing mechanism capable of reducing a falling momentum due to gravitational force of a lid that is opened and closed past the top in the perpendicular direction and easily raising the lid against the gravitational force. The opening-and-closing mechanism includes two supporting members () and an intermediate member () disposed so as to be relatively rotatable about a rotation axis; a first damper (R), disposed between a first one of the supporting members () and the intermediate member (), for generating resistance against rotation during relative rotation of the two supporting members () in one direction; a second damper (L), disposed between a second one of the supporting members () and the intermediate member (), for generating resistance against rotation during relative rotation of the two supporting members () in another direction; and rotation-restricting portions (R,L) for restricting relative rotation ranges of the two supporting members () and the intermediate member ().
