[0041]The intermediate tube 43 can be disposed in the intermediate housing portion 15 and can be coupled to the front tube portion 41 and the rear tube portion 42. Further, the intermediate tube 43 can be coupled to the multi-tube 44. Further, the multi-tube 44 can be coupled to the port 53 of the multi-valve 5. In other words, the multi-tube 44 can be disposed between the intermediate tube 43 and the multi-valve 5 to be connected to the port 53 and the intermediate tube 43 of the multi-valve 5.

[0042]In the gas fuel storage device as described above, since the housing 1 can be mounted on the lower side of the body 6, the gas storage capacity can be easily ensured than the existing gas container, the internal space of the body 6 does not need to be set. The support body of the existing large gas container is mounted, and the internal space and trunk of the vehicle can be prevented from being reduced due to the housing 1, and therefore, the internal contained inner contained in the vehicle can be prevented from deteriorating.

[0043]Further, the gas fuel storage device can utilize the existing battery housing for the electric vehicle without re-designing the housing 1, and thus can reduce the investment cost. For example, the battery power terminal is typically mounted at the rear side of the battery housing. Therefore, the multi-valve 5 can be mounted on the rear side of the battery housing mounted with a power supply terminal without having to modify the battery housing separately. Further, with the case of using a small size of the gas container 2, the gas fuel storage device has an advantage of the gas container having the gas container with the existing gas container 2.
