Abstract

PURPOSE:To reduce the load acting on the bolting section for fixing a bracket to a motor bicycle body frame by fitting the protrusion section of a step mounting bracket into the recess section which is formed on the body frame and bolting the flange section of the bracket to the body frame. CONSTITUTION:The rear section of a pair of right and left lower down tubes 19 which is a part of the body frame of a mtorcycle for motocross contests are inserted into a pair of right and left fitting sections 20a of a cross member 20 and are welded there, and the cross member 20 is formed with circular holes 20i both sides in the right and left directions, and a bearing section 21 is formed at the bottom section of each circular hole 21i. In this case, the protrusion section 37a of the step mounting bracket 37 comprising a mounting section 37c mounted a step 40 thereon is fitted into each circular hole section 20i. In addition, a step mounting bracket 37 is formed with a flange section 37b, which is connected to the outer side face of a rear arm bracket 8, and this flange section 37b is connected to the outer side face of the bracket 8 and is fixed by screwing a bolt 38 with a nut 39.
