<p>PROBLEM TO BE SOLVED: To provide a movable member pop-up mechanism using a solenoid in which a spring force in order for the movable member to pop up can be charged in linkage with the movable member, allowing the movable member to be smoothly accommodated with a light operating force.SOLUTION: The movable member pop-up mechanism comprises: a movable member 1 for popping up in such a manner as to be capable of being accommodate in and pushing out from a body; a solenoid 8, having a movable part 9, for holding the movable member 1 in an accommodated state when its adhesion to the movable part 9 is set to be strong, the strength of adhesion being switched between strong and weak by on/off of electric conduction; an urging member 6 provided with urging characteristics so as to urge the movable part 9 of the solenoid 8 to move in a direction to release the accommodated state when the adhesion of the solenoid 8 is set to be weak, the urging force being weakened when the movable member 1 pushes out and strengthened when the movable member 1 is accommodated; a slant part 1b provided to the movable member 1 diagonally to its pushing-out direction; and an urging force imparting member 5 for rotating in contact with the slant part 1b when the movable member 1 is pushed down, gradually strengthening the urging force of the urging member 6.</p> |
