Since the corner portion of the rectangular hole 22 to which a force is applied during this rotation is formed into an arc shape R, and further, the arc 21c is formed at the rear end portion of the boss 21, the footrest body 2
It has the advantage of smooth rotation. Moreover, since the lateral groove 4a extends to the right end of the floor pad 4, it does not hinder the rotation of the footrest body 2. In addition, in the type in which the footrest 1 is not mounted, if the vehicle body common to the vehicle in which the footrest 1 is mounted is used, the stud bolt 16
Is projected, the stud bolt 1 can be attached by attaching the clip 15 to the stud bolt 16 as shown in FIG.
6 heads can be covered.

FIG. 13 shows a modification of the above embodiment. The shape of the footrest main body 2 is the same as that of the footrest main body 2 described above, and thus is denoted by reference numeral 2. The difference from the above-described embodiment is that instead of the stud bolts 16, a bracket 31 having a crank-shaped cross section is fixed to the floor panel 5 by welding, and the head 32 of the bracket 31 is fixed.
Instead of the clip 15, it is formed in a substantially semicircular shape. A protrusion 33 is formed in the center of the head 32. Thus, instead of the clip 15, the head portion 32 of the bracket located on the insertion opening side of the clip holding portion 12 has the same shape as the head portion 15a of the clip 15 of the above-described embodiment, whereby the footrest main body 2 The head 32 of the bracket 31 can be fixed to the guide rails 12 a and 12 b of the clip holding portion 12.

Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications and changes can be made based on the technical idea of the present invention. For example, in the above embodiment, as shown in FIG.
