<P>PROBLEM TO BE SOLVED: To provide a hinge mechanism which is configured to rotate through mutual engagement members provided on an opening and closing member without using a separate hinge pin while generating opening resistance according to the opening of the member. <P>SOLUTION: In the hinge mechanism, a frame having a circular or semicircular fulcrum shaft part at a tip thereof and a frame having an elastic pressing part adjacently opposed to the fulcrum shaft part are integrally molded and formed as an integrated one on the inner surface of one member, and an engagement frame having a semicircular inner circumferential surface making sliding contact with the fulcrum shaft part formed on the one member and an eccentric circular outer circumferential surface in which the distance from the center point of the fulcrum shaft part to the tip is gradually extended is integrally formed on the inner surface of the other member. The semicircular inner circumferential surface of the engagement frame formed on the other member is rotatably engaged with the fulcrum shaft part of the one member, and the eccentric circular outer circumferential surface of the engagement frame is held by the elastic pressing part adjacently opposed to the fulcrum shaft part reciprocatably and rotatably by elastic pressing force. <P>COPYRIGHT: (C)2013,JPO&INPIT |
