A cylindrical hydrogen tank is housed under a floor tunnel, which is disposed at the center in a vehicle width direction of a floor panel along a vehicle front-back direction so as to protrude upward along a height direction, and includes a casing having a load bearing property. A seat cross member is disposed on a side of the hydrogen tank along the vehicle width direction. A seat pipe is joined to the seat cross member and disposed so as to extend along the vehicle width direction. The seat pipe and the seat cross member are arranged within the height of the hydrogen tank in a vehicle height direction, and also respectively located above and below the most outwardly protruded lateral end point in the vehicle width direction of the hydrogen tank.

In one embodiment, a utility vehicle includes a plurality of ground-engaging members configured to contact a ground surface, and a powertrain assembly operably coupled to the ground-engaging members. The utility vehicle also includes a frame supported by the ground-engaging members and extending along a longitudinal axis of the utility vehicle. The utility vehicle further includes a tunnel member coupled to the frame and extending along the longitudinal axis. The tunnel member is positioned at a first height from the ground surface. Additionally, the utility vehicle includes a cargo portion supported by the frame and positioned generally rearward of the tunnel member. The cargo portion has a cargo surface substantially aligned with the tunnel member and positioned at a second height from the ground surface. The first height is approximately equal to the second height.

A vehicle understructure includes a hydrogen tank that is disposed along a longitudinal axis of a vehicle. At least an upper portion of the hydrogen tank is enclosed in a floor tunnel. The hydrogen tank includes dome portions that are disposed at both ends of a cylindrical center body portion of the tank, and at least one valve portion that protrudes from at least one of the dome portions. The vehicle understructure also includes a brace that extends along a transverse axis of the vehicle and is secured to transversely outer side portions of the floor tunnel. The brace is at least partially overlapped with at least one of the dome portions when viewed from the front or rear of the vehicle.

A vehicle includes: a vehicle body; a gas tank having a tank main body that includes a cylindrical barrel part and a cap that is provided at one end of the tank main body in a longitudinal direction; a bracket fixing the cap to the vehicle body; and a band surrounding an outer circumferential surface of the barrel part and fixing the barrel part to the vehicle body, wherein the gas tank is arranged such that the longitudinal direction extends along a front-rear direction of the vehicle, the bracket includes an engaging part that restrict movement of the gas tank in the longitudinal direction by engaging with an engaged part provided in the cap, and movement of the gas tank in the longitudinal direction is restricted by the engaging part only at the one end, and not at the other end, of the gas tank in the longitudinal direction.

A fuel cell vehicle includes a first tank, a second tank, first and second valves for releasing gas, a gas passage for supplying gas to a fuel cell via the first and second valves, a pressure-reducing valve for decompressing the gas, side members disposed on the respective sides of the vehicle, and a motor disposed rearward of the second tank and configured to drive wheels. The first tank is not disposed downstream of the second tank, on the gas passage. The pressure-reducing valve is disposed in a region located rearward of a rear end of the second tank in a vehicle front-rear direction, forward of a rear end of the motor in the vehicle front-rear direction, and between one of the side members and an extended line extended in the vehicle front-rear direction from a side wall of the motor. The pressure-reducing valve is disposed on the second valve side.
