ABSTRACT:
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.
