Front vehicle-body structure of vehicle

摘要

A protecting member comprises a pair of right-and-left brackets extending obliquely downward and forward from front portions of a pair of right-and-left side frames and a stiffener extending in a vehicle width direction below a bumper beam and attached to front ends of the brackets. The stiffener has a closed cross section extending in the vehicle width direction, and an upper face of its central portion in the vehicle width direction has a concaved portion. A lower face of the stiffener extends horizontally substantially straightly. It is preferable that the closed cross section of the central portion of the stiffener be configured such that its vertical distance is relatively small and its longitudinal width is relatively large, compared with the other part of the stiffener.

1. A front vehicle-body structure of a vehicle, comprising:
a pair of right-and-left side frames extending longitudinally at a front portion of a vehicle body; a bumper beam extending in a vehicle width direction and attached to front ends of the pair of right-and-left side frames; a pair of right-and-left brackets attached to the pair of right-and-left side frames or a suspension cross member attached to the pair of right-and-left side frames and extending obliquely downward and forward; and a stiffener extending in the vehicle width direction, arranged below the bumper beam, and attached to front ends of the pair of right-and-left brackets, wherein said stiffener has a closed cross section extending in the vehicle width direction substantially over an whole length thereof and is configured in an elevational view such that an upper face of a central portion thereof in the vehicle width direction is concaved and a lower face thereof extends horizontally substantially straightly, and said central portion, in the vehicle width direction, of the stiffener is configured such that a distance between the upper face and the lower face thereof is smaller than a distance between the upper face and lower face of the other part of the stiffener and a longitudinal width thereof is larger than a longitudinal width of the other part of the stiffener.
