To provide a floor tunnel structure for a vehicle body improved in strength of a floor tunnel while restricting an increase in size.SOLUTION: A floor tunnel structure for a vehicle body comprises: a floor tunnel 2 provided at a central part in a vehicle width direction of a floor of a vehicle body; and a reinforcement bracket 3 disposed on an upper surface 2a of the floor tunnel 2. The reinforcement bracket 3 has: a first stationary portion 37 mounted on the upper surface 2a of the floor tunnel 2; a second stationary portion 38 provided further backward than the first stationary portion 37 in a forward and backward direction and rightward in a vehicle width direction; and a third stationary portion 39 provided further backward than the first stationary portion 37 in the forward and backward direction and leftward in the vehicle width direction. An imaginary line T connecting the first stationary portion 37, the second stationary portion 38 and the third stationary portion 39 is formed in a truss shape as viewed from a vertical direction of the vehicle body.SELECTED DRAWING: Figure 1

    【課題】大型化を抑制しつつフロアトンネルの強度を高めた車体のフロアトンネル構造を提供する。【解決手段】車体のフロアにおける車幅方向の中央部に設けられ、車体の前後方向に沿って延びるフロアトンネル2と、フロアトンネル2の上面2aに配置される補強ブラケット3と、を備え、補強ブラケット3は、フロアトンネル2の上面2aに取り付けられる第一固定部37と、第一固定部37よりも前後方向の後方かつ車幅方向の右方に設けられる第二固定部38と、第一固定部37よりも前後方向の後方かつ車幅方向の左方に設けられる第三固定部39と、を有する。第一固定部37、第二固定部38及び第三固定部39を結ぶ仮想線Tは、車体の上下方向から見てトラス状に形成される。【選択図】図1
