摘要： A vehicle body structure includes: a dash panel extending in a vehicle width direction and defining a cabin and a power compartment in front of the cabin; a power unit arranged in the power compartment; a floor panel extending rearward in the cabin from the dash panel; and a dash crossmember projected forward from the dash panel and extending in the vehicle width direction. The dash crossmember has: a first portion at least partially overlapping the power unit in a front view at the time when a vehicle is seen from front; and a second portion extending outward in the vehicle width direction from the first portion, and compressive strength of the first portion is lower than compressive strength of the second portion.

摘要： [Problem] Provided is a front vehicle-body structure of a vehicle that suppresses deformation of a floor panel in an oblique collision.
[Means for Solution] The front vehicle-body structure of the vehicle includes: a floor panel 60; a side sill 30; a floor frame 50 extending in a front-rear direction on a vehicle-width-direction inner side of the side sill 30; a first cross member 10 connecting a front portion of the side sill 30 and the floor frame 50 to each other in a vehicle width direction; and a second cross member 20 connecting the side sill 30 and the floor frame 50 to each other in the vehicle width direction on a rear side of the first cross member 10. In the front vehicle-body structure, the floor panel 60 has a quadrilateral closed region 80 surrounded by the side sill 30, the floor frame 50, the first cross member 10, and the second cross member 20 on a periphery of the quadrilateral closed region 80, and a bead 86 linearly extending in a direction intersecting with a virtual line L1 connecting a front portion on a vehicle-width-direction outer side of the closed region 80 and a rear portion on a vehicle-width-direction inner side of the closed region 80 to each other at an angle of 45 degrees or more in a plan view is provided in the closed region 80.-
