<p>A gas line ( 120 ) for supplying hydrogen gas and a harness ( 110 ) for supplying power to an electromagnetic valve are connected to an electromagnetic valve mechanism ( 200 ). The length of the harness ( 110 ) from a connecting member ( 111 ) to a fastener ( 160 ) is denoted by the letter "n" and the length of the gas line ( 120 ) from a connecting member ( 121 ) to a fastener ( 170 ) is denoted by the letter "m" (n<m). During a vehicle collision, a hydrogen gas tank ( 100 ) moves, placing tension on the harness ( 110 ) and the gas line ( 120 ). The tension causes both the harness ( 110 ) and the gas line ( 120 ) to stretch. The limit value of the stretch amount of the harness ( 110 ), which is shorter between the connecting member and the fastener, is low such that the harness ( 110 ) will break before the gas line ( 120 ) is damaged. As a result, power to the electromagnetic valve mechanism ( 200 ) is cut off and the electromagnetic valve closes before the gas line ( 120 ) is damaged, thus preventing a gas leak.</p> |
