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.

A wave absorbing structure for a fuel tank, comprising a wave absorbing member having a resistance member through which fuel can pass and which imparts resistance to the passage of the fuel, and arranged inside a tank body, the wave absorbing member being supported by a pipe that is disposed inside the tank body and passes through a through hole formed in the wave absorbing member,
- wherein the pipe comprises a movement restricting member that restricts movement of the wave absorbing member along the pipe by abutting against a wall of the wave absorbing member surrounding an opening portion of the through hole.
