Because the rear edge of the fender panel (door opening side) is provided with a flange over almost the entire length in the vertical direction, the rigidity is high and it is difficult to deform, while the wheel cut side has low fender panel rigidity and easily deforms, The setting posture of the door opening line is distorted.

Particularly, in a front-wheel drive vehicle (so-called FF vehicle), the size of the rear end lower portion 1a of the fender panel 1 in the front-rear direction is very narrow, and the rigidity of the rear end lower portion 1a is small with respect to the force applied in this direction. The lower rear end 1a of the fender panel 1 is slightly displaced by the torque in the direction of arrow T when the bolt 2 is tightened, and the two-dot chain line S
In the area indicated by, the door opening line L is disturbed,
It was found to be a cause of poor appearance. When the rear end lower portion 1a of the fender panel 1 is fixed with only one bolt 2, there is another problem that the support of the rear end lower portion 1a tends to be unstable.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a mounting structure for a fender panel that can fix the rear end lower portion of the fender panel using one bolt without any problem.
