A fluid-filled chamber may include a pair of polymer layers that define a plurality of subchambers and a web area. The subchambers are protruding portions of the polymer layers that enclose a fluid, and the web area is portions of the polymer layers that are located between the subchambers and lay adjacent to each other. The subchambers may have greater thickness than the web area. A perimeter bond joining the polymer layers and extends around a periphery of the chamber. In addition, a plurality of interior bonds join the polymer layers and extend around the subchambers, which may seal the fluid within the subchambers.

A molding device of an inbuilt component fixing section of a fuel tank includes: a projection member that projects out at a placement face onto which a resin sheet that will form a tank configuration member is disposed in a molten state, and that molds a hollow bulge section in the resin sheet; an elastic body that covers the projection member, and that expands and applies pressure to the bulge section from the inside due to a non-compressible fluid being supplied into a sealed space formed between the elastic body and the projection member; a fluid supply device that supplies the fluid into the sealed space in a state in which the bulge section has penetrated through a fixing hole provided in an inbuilt component; and a fixing member that fixes a location of the elastic body corresponding to a leading end portion to the leading end portion.
