Abstract
A lid urging structure includes a housing, a lid pivotally supported on the housing via a link member and switched among a closed position where the lid closes an opening in the housing, a first position in the middle of opening from the closed position, a second position located further in an opening direction, and a fully open position; and an urging member that urges the lid in a closing direction at the closed position and, when the lid is pivoted from the closing direction to the second position by overcoming the urging force, the urging direction is reversed, enables switching from the second position to the fully open position by the urging force. The urging member is formed of a plurality of springs disposed between the link member and the housing. The operating force and the urging force are adjusted by means of a balance between the springs.
