PROBLEM TO BE SOLVED: To simplify fitting structure, and reduce the number of part items, by extending both the right and left lower end pats of a load-carrying platform, fitted to the frame rear part of a bicycle, downward to rotatably fit auxiliary wheels, and fitting rear fender to the upper end part of the load carrying platform. SOLUTION: A rear end part, extending downward from the fitting part of the divided body 15A of a load-carrying platform, is adopted as a fitting part for auxiliary wheels 14 to provide a spindle fitting hole 96, and the boss part 97 of the auxiliary wheels 14 is rotatably fitted by a fitting spindle 98, having a screw part 98A in one end, and a nut 99. A screw insertion hole 102 is provided in a connecting screw 101, penetrating in a right and left direction to a joining surface 100, on the upper end part of the divided body 15A of the load-carrying platform; and is fittedly fixed by a nut 103 threadedly engaged with a connecting screw 101. The fitting hole 104 of a rear fender 17 is penetratedly provided, in a right and left direction with vertical height different in fore and rear, on the lower side of the screw insertion hole 102; and a rear fender 17 is detachably fitted by an attaching screw 105 and a nut. This can reduce the number of part items to simplify fitting structure to a frame rear part 2B, and simplify and facilitate assemling work. |
