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
