2. Description of the Related Art Conventionally, a front fender panel (hereinafter abbreviated as a fender panel) is known as a panel member that forms an arched vehicle body side wall portion near a front wheel house.
This fender panel is attached to a vehicle body constituting member such as an apron reinforcement or a hinge pillar via a support stay or a bracket.
Generally, a fender panel is formed by pressing a metal plate material using a mold, and includes a side wall portion that is a design surface, a vertical wall portion that is connected to the side wall portion via a ridge line, and the vertical wall portion. And a flange portion connected through a bent portion are integrally formed (Patent Document 1).

When corners are formed on the side wall of the fender panel, the peripheral parts of the corners are deeply squeezed by pressing during molding, and the stress associated with this drawing is concentrated on the corners. There is a risk of causing damage to the part. This is a problem particularly when an aluminum or aluminum alloy panel is used.
Therefore, a weakened portion where the peripheral portion is weakened so that the material easily flows from the peripheral portion other than the corner portion toward the corner portion, such as an opening portion for reducing rigidity in the peripheral portion of the corner portion of the flange portion, etc. Forming a material flow promotion mechanism has been performed.

In addition, when the bumper fascia and the over fender panel are supported by the fender panel, the bumper fascia and the like vibrate due to vibrations caused by traveling when the vehicle travels, so that stress caused by those vibrations is formed on the fender panel. The ridgeline portion or the bent portion (high rigidity portion) is transmitted to the corner portion as a propagation path, and the corner portion may be damaged by this concentrated stress.
As described above, if the peripheral portion of the corner portion is weakened in consideration of formability, the support rigidity of the bumper facer and the like in the peripheral portion of the corner portion is reduced, so that vibration of the bumper facer and the like is promoted. Along with this, there is a concern that the concentrated stress at the corners may increase.
