The present floor tunnel is laid on a floor surface of a vehicle interior along a vehicle front-rear direction, extends substantially linearly along the vehicle front-rear direction, has a front end and a rear end, and has an open cross-sectional shape of a hat shape in which a shape of a cross section perpendicular to the vehicle front-rear direction protrudes from the floor surface. The floor tunnel includes a front end region that has the front end and a main region that has the rear end and continues to the front end region. When a total length from the front end to the rear end is L (mm), a boundary position between the front end region and the main region is within a range between a position at 30 mm from the front end toward the rear end and a position at L/5 from the front end toward the rear end. Yield strength of the front end region is lower than yield strength of the main region.
