Abstract
The valve control unit of a fuel leakage preventing structure of the present invention includes first and second electrodes. The first electrode is attached to a first member that is movable. When a pressing force is applied to the first member to move, the first and second electrodes are brought into contact with each other, to cause conduction. The first and second electrodes are connected to a control device, and the control device opens a control valve when the first and second electrodes are put into a conducting state. As the control valve is opened and closed by a pressing force in this manner, a fuel solution can be easily supplied.
