摘要： Provided is a receptacle cap with a simple structure capable of preventing fixation of a receptacle and a filling nozzle. A receptacle cap is configured to be removably attached to a receptacle that connects to a fuel gas filling nozzle. The cap includes a top panel portion that blocks an opening of the receptacle, a skirt portion extending along an outer peripheral wall of the receptacle, and a liquid absorbing portion provided at least on an inner peripheral wall of the skirt portion. The liquid absorbing portion is arranged so as to be in contact with the outer peripheral wall of the receptacle when the cap is being attached to the receptacle.

摘要： A vehicle comprises a tank that is placed behind a front component in a front-rear direction of the vehicle and that is arranged such that a longitudinal direction of the tank is along the front-rear direction; and a fixation member configured to fix the tank to a vehicle body of the vehicle. The front component and the tank are arranged to at least partly overlap with each other when the vehicle is viewed from a forward direction side. The fixation member releases fixation of the tank to the vehicle body when the front component comes into contact with the tank to apply an external force along the longitudinal direction that is equal to or greater than a predetermined value, to the tank.

摘要： To suppress the influence of gas on other fuel tanks when the gas is discharged from a fuel tank. A fuel storage device includes: a plurality of fuel tanks, each having a fusible plug valve; a support member that supports the plurality of fuel tanks, while making longitudinal directions of the respective fuel tanks parallel to each other; and a blocking member that blocks at least part of the fuel gas discharged from the fusible plug valves. The plurality of fuel tanks includes a tank group including the plurality of fuel tanks aligned along a first direction and a juxtaposed tank thereto. The blocking member is disposed between the tank group and the juxtaposed tank. The orientations of openings of the fusible plug valves included in blocked tanks are directed toward the blocking member, the blocked tanks being two or more fuel tanks that are continuous in the first direction, among the fuel tanks included in the tank group.
