In the opening/closing mechanism, the torsion bar is composed of two elastic members each having a twist angle, and the torsion bar is in contact with each of the elastic members. An opening/closing mechanism having a torsion bar, characterized in that a contact member that increases the torsion angle is formed on a mounting portion of the other unit.
