Abstract

A dash-board lower panel (19) in a vehicle body (11) includes a vertical plate-shaped partition plate (41) which partitions the vehicle body into a front and a rear section, and an inclined plate (43) which inclines downward and rearward from the bottom end of the partition plate. At least part of the rear surface (19a) of the partition plate is reinforced by a reinforcement plate (28). The reinforcement plate has an extended section (92) at the bottom end thereof. The extended section extends from above a bent section (42), which is between the partition plate and the inclined plate, to below the bent section, and is joined to the inclined plate. A closed cross-section body (93), which is long and narrow in the vehicle-width direction, is formed by the extended section and the dash-board lower panel.

Description

technical field [0001] The present invention relates to a vehicle body front structure, which includes: left and right front side frames located on the left and right sides of the front part of the vehicle body and extending in the front and rear directions of the vehicle body; and behind the left and right front side frames And the vehicle body is divided into front and rear dashboard lower panels. Background technique [0002] The dashboard lower panel includes: a vertical plate-shaped dividing panel formed to divide the vehicle body into front and rear; and an inclined panel inclined rearward and downward from the lower end of the dividing panel. Generally, the lower panel of the dashboard is reinforced by a beam extending in the vehicle width direction. From Patent Document 1 and Patent Document 2, it is known that the lower panel of the instrument panel is reinforced by a beam. [0003] The lower panel of the instrument panel known from Patent Document 1 is composed o...
