Definitions
- the present invention relates to a front body structure of an automobile having an apron member disposed above a pair of left and right side members extending in the vehicle front-rear direction such that a front end thereof is located behind a front end of the side member.
- automobiles may adopt a structure in which, for example, a headlight is arranged so as to extend from a front side of a vehicle body to a side surface of the vehicle body in order to improve the appearance.
- the left and right apron members connected to the front pillars should have the front ends behind the front ends of the left and right side members to secure the space for the headlights.
- the apron member and the side member are connected by a fender apron (for example, Japanese Patent Application Laid-Open No. 2002-466648).
- the present invention has been made in view of the above-described conventional circumstances, and reliably transmits an input at the time of a collision from a side member to an apron member, thereby suppressing upward deformation of the side member and suppressing pitching at the time of a collision.
