The invention includes a floor reinforcement structure for vehicle body providing rigidity to an area around a main and rear floor joint; improving vehicle-body rigidity and rigidity against floor shaking and associated vehicle interior noise; and improving vehicle running stability. A floor reinforcement structure includes: a main floor; rear floor; side sill; a floor tunnel with a hat-like cross-section protruding from the floor and located medially in the main floor in the vehicle width direction and extending in a front-and-rear direction; and a vertical wall at the front of the rear floor extending in a vehicle vertical direction. The vertical wall is continuous with no steps The height of a top face thereof is larger than twice the height of a top face of the side sill, which is more than twice the height of a top face of a rear end portion of the floor tunnel. |
