Zusammenfassung:	PROBLEM TO BE SOLVED: To suppress efficiently, ambient noise and impact which are generated due to oscillation of a liquid fuel in a tank body, and reduce affection to a storage volume of the liquid fuel in the tank body as much as possible.SOLUTION: A fuel tank structure for vehicle comprises, in a tank body 1 for storing a liquid fuel 8, suppression means 7 for suppressing ambient noise and impact which are generated due to oscillation of the liquid fuel 8. The suppression means 7 is formed by incorporating plural buffer floating small pieces 4 formed of fuel-resistant impermeable material. In each of the buffer floating small pieces 4, an air chamber 5 having a float function, is formed. 【課題】タンク本体内における液体燃料の踊動により発生する騒音や衝撃を効率よく抑制する共に、タンク本体の液体燃料の貯蔵容量への影響を極力少なくすべく構成している。【解決手段】液体燃料８を貯蔵するタンク本体１内に、液体燃料８が揺動することによって発生する騒音や衝撃を抑制する抑制手段７を備えた車両用燃料タンク構造であって、抑制手段７が、タンク本体１内に耐燃料不浸透材からなる緩衝浮遊性小片４を多数内蔵することによって構成されている。緩衝浮遊性小片４の内部には、浮き子機能を有する気室５が形成されている。【選択図】図３
