ABSTRACT:
The invention provides an operational mechanism for a movable body in which, after a movable body is in an opened state, the movable body can return to a closed position, including a movable body rotatably attached to a support and rotatable between an engaged position, a closed position, and an open position; a rotating member rotatably attached to the support, that rotates due to movement of the movable body to the engaged position; a biasing member, one end of which is attached to the movable body, and the other end of which is attached to the rotating member; and an operation member, which rotates the rotating member, changes the biasing position of the biasing member with respect to the center of rotation of the movable body, and generates in the biasing member a rotational force that moves the movable body to the closed position or the open position.
