Abstract: A wave absorbing member including a cage-shaped container housing a sponge that imparts resistance to the passing of fuel is arranged inside a tank body. Therefore, an impact by collision of the fuel can be absorbed, noise caused by undulation of the fuel can be reduced, and violent undulation of a fuel level can be effectively suppressed by the wave absorbing member. The wave absorbing member is supported by a pipe that is arranged inside the tank body and passes through a through hole formed in the container. A movement restricting member is provided on the pipe to limit movement of the wave absorbing member along the pipe. Therefore, the wave absorbing member is reliably positioned along the pipe and within the tank body with a simple structure.
