form. The notches 10, 10 are formed only on the front edges 16 of the mounting legs 9, 9, and the rear edges 17 of the mounting legs 9, 9 are formed as straight edges from beginning to end.

The upper and lower ends of the notch 10 form engaging portions 11 and 12. The notch 10 has a dimension greater than the thickness of the plate 7, and is formed on the front side 13 so that the opening of the notch 10 faces forward.

14 is a bent part formed between the engaging part 11 and the engaging part 12, and the distance between the bent part 14 and the engaging part 11 is formed to be equal to the thickness of the plate 7. The bent portion 14 has a dogleg shape in a direction perpendicular to the direction of travel of the vehicle. 15 is the periphery of the mounting hole 8.

(effect) Next, we will discuss the effect.

When attaching the bracket 5 to the plate 7,
First, the tip of the mounting leg 9 is aligned with the mounting hole 8 from above (FIG. 5A), and then the bracket 5 is press-fitted in the direction of arrow N in FIG. 5B. At this time, the mounting leg 9 is bent inward by the bending portion 14 and then restored. As a result, the upper end portion of the bent portion 14 is connected to the mounting hole 8.
When the center pad 1 is further pushed forward (arrow H side) by hand, the bracket 5 moves and the mounting hole periphery 15 of the plate 7 forms the notch 10. engage within. As a result, the engagement part 11 and the bent part 14 form the mounting hole peripheral part 1.
