A fuel sloshing noise of the fuel tank reduction device is provided to reduce the sloshing noise by mounting the baffle rotating at the opposite direction of the automotive inertia power to the fuel tank part. A fuel sloshing noise of the fuel tank reduction device comprises the respective fixed supporting part(20) in the inside both ends of the fuel tank(10); the baffle(30) pivotally combined in the supporting part; the rotation weight(40) pivotally combined in the supporting part; and the interlocking means(50) which it mutually works so that baffle rotate at the opposite direction as the rotation weight rotates. The torque of the inertia rotation axis by the rotation weight, is greater than the torque of the baffle axis of rotation by baffle.
