PURPOSE: Baffle structure of a fuel tank is provided to minimize flowing of fuel and reduce noise caused by the flowing of fuel and noise amplified by resonance by installing rotating shafts forming buffering vanes to the bottom of the fuel tank and installing driving gears at the ends of the rotating shafts. CONSTITUTION: In baffle structure of a fuel tank(1), two pairs of supports(11,21) are installed to the bottom of the fuel tank at regular intervals and rotating shafts are rotatively supported between the supports. First and second buffering vanes(13,23), rotating according to the flowing direction of fuel, are protruded to the rotating shafts. The first and second buffering vanes work as resistance against the flowing of fuel. First and second driving gears(14,24) are formed to the end of the rotating shafts, and the first and second driving gears are engaged with each other. Plural flow grooves(16,26) are formed to the first and second buffering vanes. Bent parts(15,25) are formed to the end of the first and second buffering vanes.
