When a fuel tank inclines, a valve body device for the fuel tank restricts the flow of fuel to the exterior of the fuel tank, thereby preventing environmental pollution and improving fuel consumption. A rise/fall member and a valve body are lowered by an urge force less than a combined weight of the valve body and the rise/fall member, thereby creating an opening in a valve portion. A coil spring expands and the valve body contacts convex portions on a first inner surface of a cylinder main body. After a pressure reduction at a communication port of a resistance member, the fuel flows from a small-diameter space of a blow-up member, so that the flowing fuel pushes up the valve body and the rise/fall member closes the valve portion together with the urge force of the coil spring.
