<P>PROBLEM TO BE SOLVED: To reduce backlash produced in an opening and closing lid 2 in the direction of a hinge shaft, in an opening and closing lid mechanism in which a housing chamber 11 is formed in a housing 1, and the housing chamber 11 is covered with the opening and closing lid 2 having a base end part pivotally supported by the hinge shaft. <P>SOLUTION: In this opening and closing lid mechanism, a slidably operable slide plate 3 is disposed in the opening and closing lid 2 so as to be able to reciprocate along one direction, the slide plate 3 locks the opening and closing lid 2 at a closing position by sliding in the one direction with the opening and closing lid 2 closed. A cam mechanism functioning when the slide plate 3 slides in the above mentioned one direction with the opening and closing lid 2 closed is interposed between the facing parts of the open fringe of the housing chamber 11 of the housing 1 and the peripheral fringe of the opening and closing lid 2 which are to face each other with the opening and closing lid 2 closed, and the cam mechanism applies pressing force in a direction along the axial direction of the hinge shaft 41 to the opening and closing lid 2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
