1. A fuel tank comprising:
- a resin tank body;
an in-tank functional component provided inside the tank body; and
a shock-absorbing baffle member formed into a shape mountable to the in-tank functional component, said shock-absorbing baffle member comprising a plurality of foam members each having a hollow bore extending through a central portion thereof, wherein the foam members are formed from a foamable fuel-tolerant material and arranged in a sequence on an elongated support member,wherein the in-tank functional component comprises a resin pipe member having both ends thereof fixed inside the tank body, and wherein the resin pipe member functions as said elongated support member.

Abstract
An improved fuel tank is disclosed. In the fuel tank, a shock-absorbing member comprising a plurality of foam members is mounted to an in-tank functional component provided inside a resin fuel tank body. When the fuel inside the tank sloshes up and down, the fuel strikes the shock-absorbing member, causing the force of the waves to be dispersed, and reducing the fuel sloshing sound created by the sloshing of the fuel.
