A fuel cell vehicle mounted with a fuel gas tank in an underfloor of the vehicle. The fuel cell vehicle includes: a floor that has a projecting portion projecting upward in a height direction of the vehicle and extending along a front and rear direction of the vehicle; a fuel gas tank arranged under the projecting portion in the height direction of the vehicle and fixed to the floor; and an undercover arranged under the fuel gas tank in the height direction of the vehicle. The undercover has a fixation protruded portion that projects upward in the height direction of the vehicle in a side of the fuel gas tank in a width direction of the vehicle, and being fixed to the floor by the fixation protruded portion.

A vehicle chassis arrangement, preferably for use in an agricultural tractor. The chassis has two frame elements and a differential housing, where the ends of the frame elements are connected to the side of the differential housing facing the rear of the vehicle. A tank cover is attached adjacent to that side of the differential housing, to define a fluid storage tank between the tank cover and the surface of the differential housing.

A positioning apparatus for positioning a tubular fluid container in an elongate carrier which is configured as a hollow profile. In order to simplify the positioning of the tubular fluid container, the positioning apparatus includes spring elements, by way of which the tubular fluid container is positioned in the elongate carrier.

The present invention provides for an improved air tank cross member (ATCM) deployable in a vehicle chassis. The ATCM comprises one or more structural elements comprising a tube forming an enclosure for holding a compressed fluid and having mounting extensions on an outer surface of the tube. The structural elements comprise two or more brackets connected to the mounting extensions of the tube and a pair of end caps disposed at opposite ends of the tube for forming the enclosure. The brackets are attached to the end caps by a fastening means to form a unified mounting geometry. The arrangement and construction of the structural elements of the ATCM provide for space-saving and weight-saving and increases stiffness value of one or more stiffness parameters of the vehicle chassis.

A vehicle reinforcing member includes first and second pistons movable in an axial direction in a cylinder. An inside of the cylinder is sectioned into a gas chamber and a main liquid chamber by the first piston, and the main liquid chamber is sectioned into a first sub-liquid chamber and a second sub-liquid chamber by the second piston. Gas is sealed in the gas chamber, and liquid is sealed in the first and second sub-liquid chambers. A piston rod is coupled to the second piston. The cylinder and the piston rod are respectively coupled to two locations of a vehicle body. A communication path connects the first sub-liquid chamber to the second sub-liquid chamber. A moving amount of the liquid in the communication path is adjusted by an adjuster such that a moving load through the second piston is adjusted.

An electrically driven vehicle comprises: a body frame arranged in a holding compartment formed in front of a passenger compartment; a suspension member fastened to the body frame in the holding compartment through a rear side fastening structure; and a fuel cell stack supported on the suspension member through a rear side mount at a position in front of the rear side fastening structure. When a serious collision occurs, the fuel cell stack moves rearward and strikes the fastening structure whereby the fastening structure breaks and thereby suspension member separates from the body frame and the fuel cell stack moves downward and heads toward the inside of the shelter space between the holding compartment and a road surface.
