In consideration of the shape of the splash guard 1 and the rear fender panel 28, it is effective to arrange the splash guard 1 in a shape or a narrow place where the splash guard 1 cannot be attached by a clip.

  As shown in FIG. 10, the clip attachment portion 17a formed on the bottom wall 7 of the splash guard 1 is attached to the vehicle body via the clip 30, but the clip attachment portion 17a has a cross-sectional shape (cross-sectional view in the longitudinal direction of the vehicle body). Projecting upward toward the vehicle body. Thus, the mounting portion 17a protrudes because the side wall portion 7 of the splash guard 1 tends to extend to the lower side of the vehicle body, and the position of the reference surface of the bottom wall 8 of the splash guard is determined by the side body panel 4. It becomes a position away from the attachment surface to the lower side. Therefore, the positions of the attachment portions 17a and 17b are protruded upward from the reference surface of the bottom wall 8.

However, when the splash guard 1 is inclined as shown in FIG. 10, when the splash guard 1 is formed, the die-cutting direction is the direction indicated by the arrows b and c, so the portion indicated by A of the splash guard 1 is the splash guard. The die 1 cannot be removed together with the main body 1a. Normally, a slide mold is required at all locations of the clip mounting portion, which increases the cost of the mold.
However, in the present embodiment, as shown in FIG. 11, the folding piece 18 having the clip mounting portions 17 b arranged in the even-numbered portions is formed by the thin portion 19 so as to be bent. Therefore, when the splash guard 1 was formed, the entire bent piece 18 was formed at an angle so that it could be punched in the directions of arrows b and c, which are the punching directions as shown in FIG. Thereby, the clip attaching part 17b arrange | positioned at even number does not require a slide type | mold at the time of shaping | molding. As a result, the manufacturing cost of the splash guard 1 is reduced. In addition, the clip attachment part 17a arrange | positioned at odd number uses a slide type | mold conventionally.

The embodiment of the present invention has been described above, but various modifications and changes can be made based on the technical idea of the present invention as well as the present invention.
For example, in the above-described embodiment, the number of the bent pieces 18 can be arbitrarily changed and can be arranged in all the clip mounting portions, but it is desirable to change the arrangement location appropriately in consideration of the strength balance.
