In this example, the front side fastening portion 32 and the rear side fastening portion 33 are disposed so as to substantially overlap in a vehicle front view, but may be slightly deviated in the vehicle width direction. By providing the flange 31 horizontally in the longitudinal direction of the vehicle, the rigidity for receiving the longitudinal load from the headlamp 10 is improved.

  In the vehicle front structure of the present embodiment, the vehicle body side upper side connection portion 21 provided on the lamp support panel 20 is connected to the front fender bracket 41 via the fender panel 30 (FIG. 5). With respect to the vehicle longitudinal load acting on the headlamp 10, a part of the load is transmitted from the lamp upper connection portion 11 to the vehicle body upper connection portion 21. The load transmitted to the vehicle body side upper connection portion 21 is transmitted from the fender upper connection portion 25 to the front side fastening portion 32 and further to the rear side fastening portion 33 via the flange 31.

  With this configuration, the vehicle front-rear direction load of the headlamp 10 can be efficiently received by the fender panel 30, more specifically, by the linear flange 31 extending in the vehicle front-rear direction. As a result, the vehicle front structure can ensure the strength and rigidity of the periphery of the lamp support panel 20 and does not add a new member, so that the weight of the vehicle front can be reduced.

  Further, as a modified example of the present embodiment, the material of the fender panel 30 may be changed to a metal material to be a resin material. Thereby, molding of the front side fastening portion 32 and the rear side fastening portion 33 provided on the flange 31 becomes easier than in the case of the metal material. In addition, the thickness between the front fastening portion 32 and the rear fastening portion 33 can be easily changed as necessary.

  As can be seen from the above description, according to this embodiment, it is possible to effectively receive the vehicle front-rear direction load of the headlamp 10 without adding a new member for fixing the headlamp 10.

  The description of the above embodiment is an example for describing the present invention, and does not limit the invention described in the claims. Moreover, each part structure of this invention can be variously deformed within the technical range as described in not only the said embodiment but the claim.

  For example, in the present embodiment, the flange 31 is formed so as to extend horizontally in the vehicle longitudinal direction, but may be formed so as to be inclined in the vehicle vertical direction or the vehicle width direction. Further, the width in the vehicle width direction of the flange 31 (the amount of projection from the inner side surface of the fender panel 30) does not have to be the same. For example, it may be formed to become larger toward the rear of the vehicle.

  Moreover, although the fender panel 30 is attached to the front fender racket 41, it is not restricted to this. The side frame 40 may be provided with a fender attachment.
