A spacing member 13 is welded between one end each of a pair of right and left plate materials 12, 12 of this foot rest bracket 11. Thereafter, installation holes 14, 15 are drilled on both of the plate materials 12, 12, and the installation hole 15 is fixed tightly in the foot rest installation part by a pivot bolt 17. The installation holes 14, 14 are tightly fixed in the installation holes of the body frame 1 by a bolt 19. Thereafter, foot rest bars 23 are tightly fixed on members 20, 20 of the foot rest bracket 11.
