Arrange a Y-shaped reinforcing member having a side of the cowl,
Set the base of the reinforcing member horizontally along the longitudinal direction of the vehicle.
And the other end of the base is connected to the front suspension
Front side member almost aligned with the front end of the receiving part
And the first branch portion is connected to one of the base portions.
It is arranged to extend diagonally from the end toward the upper side,
And the second branch portion is located below one end of the base portion.
To extend obliquely toward
Connecting the tip of the Kibe to the upper part of the front pillar lower
In addition, the second branch portion is formed along the front wheel house.
And connect the tip to the lower part of the front pillar lower.
So that it extends diagonally upward.
When the extension of the first branch that is placed crosses the roof
Both of the second branch portions are arranged to extend obliquely downward.
Because the extension line of the line crosses the side sill,
If an excessive load is applied to the front of the car from the front,
The load is applied to the fork of the reinforcing member via the base of the reinforcing member.
Smooth and appropriately distributed and transmitted to the first and second branches
The load distributed to the upper first branch is
Distributed to pillars, roof, and lower second branch
The transferred load will be efficiently transmitted to the side sill.
You. As a result, the load applied to the front pillar and the cowl is suppressed to a small value, and it is possible to effectively prevent deformation of these portions. That is, the load acting on the front of the vehicle
The impact that the front pillar and cowl receive when dispersed is small
The front pillar and cowl
Shape can be suppressed effectively. Accordingly, it is possible to prevent inconveniences such as a decrease in the windshield holding ratio (peeling of the windshield) and an increase in the amount of rearward projection of the steering wheel.
