[0007] However, in Citation 1, since the load energy acting on the suspension tower is mainly dispersed and transferred to the front body, the difference between the load energy acting on the front body and the load energy acting on the rear body becomes large, which may cause serious damage to passengers. Brings a sense of disobedience such as body distortion
Therefore, there is room for further improvement in the transmission of the load energy acting on the suspension tower in the vehicle body structure as cited in Document 1.

The purpose of the present invention is to provide a front vehicle body structure of a vehicle, the front vehicle body structure being capable of efficiently distributing and transmitting load energyacting on a suspension tower to the entire vehicle body of the vehicle. The front vehicle-body structure comprises a dash panel, a pair of right-and-left hinge pillars, and a suspension tower, whereinthe dash panel comprises a dash panel body which constitutes a partition wall positioned at a front side of a cabin portion and a dash cross member which is joined to a front face of a lower portionof the dash panel body and interconnects respective lower portions of the right-and-left hinge pillars in a vehicle width direction, and there are provided a pair of right-and-left heat-insulating inner lower portion, each of which connects the suspension tower and the dash cross member.
Description
technical field [0001] The present invention relates to a front body structure of a vehicle including, for example, a connecting member connecting a suspension tower and a dash panel at the front of the vehicle. Background technique [0002] In vehicles such as automobiles, for example, the front suspension shock absorber (hereinafter referred to as "front suspension shock absorber") that expands and contracts according to the unevenness of the road surface suppresses the up and down motion of the vehicle body and ensures the ride experience of passengers (hereinafter referred to as "front suspension shock absorber") through the suspension The tower is connected to the skeletal members of the body. [0003] Generally speaking, since relatively large load energy tends to act on the suspension tower through the front suspension damper, the suspension tower may be deflected and deformed by the load energy acting through the front suspension damper. If such deflection occurs in...
