Problems solved by technology

[0009] However, in the structure of Patent Document 1, as described above, when a pedestrian collides with the vicinity of the boundary between the bonnet and the fender, the bonnet abuts against the rain rail portion provided below the bonnet and above the apron reinforcement, I'm afraid it will hinder the downward plastic deformation of the hood
[0010] As a countermeasure, it is conceivable to further weaken the above-mentioned bracket that exists between the hood and skirt reinforcement together with the rain rail. In this case, since the support rigidity of the bracket to the fender is also reduced, the There is room for further improvement in achieving a higher level of pedestrian protection performance and fender support rigidity

Abstract

There is provided a bracket which connects an apron reinforcement (5) provided below a bonnet (3) and an upper portion of a fender (4) provided on an outward side, in a vehicle width direction, of the bonnet (3). The bracket (10) comprises a fender fixing portion (11) fixed to a flange portion (4ub) of an upper end portion (4u) of the fender (4), a body portion (12) extending downwardly from the fender fixing portion (11) and positioned on the outward side of the apron reinforcement (5), and an apron reinforcement fixing portion (13) extending from an inward side, in the vehicle width direction, of the body portion (12) toward the apron reinforcement (5) and fixed to the apron reinforcement (5). The body portion (12) is provided with a curved part (15) which is configured to be curved outwardly in the vehicle width direction.

Description

technical field [0001] The present invention relates to a front body structure of a vehicle. The front body structure of the vehicle includes, for example, an engine hood provided above a power unit, and left and right sides of the engine hood located on the outside in the vehicle width direction and provided on the sides of the vehicle body. A fender, a pair of left and right skirt reinforcements provided under the hood and extending in the vehicle front-rear direction, and a bracket that connects the upper portion of the fender and the skirt reinforcement. Background technique [0002] As the front body structure of the vehicle, as exemplified in Patent Document 1, there is generally known a structure in which a rainwater guide portion as a rain gutter is provided on the upper part of the fender; [0003] In order to catch water intruding into the interior of the vehicle body through the gap between the fender and the hood and to discharge it to the outside of the vehicle ...
