PROBLEM TO BE SOLVED: To enable an object of fitting an auxiliary wheel for carrying a bicycle to the foldable bicycle without impairing design property, with a minimum number of components, without impairing simple fold-ability and light-weight.SOLUTION: An auxiliary wheel 17 is fixed to a starting end 19 of a thumb screw moving hole for a stay 16, with a thumb screw 20. Then, a rotary shaft 12 is inserted into a stay rotary shaft hole 13 of the stay 16 and a front-and-rear-frames-connection pivot 4, to fix the stay 16. The rotary shaft 12 is provided with a step, a size of which includes: a size of a clearance allowing the stay 16 operable even when the rotary shaft 12 is bound; and a thickness of the stay 16. Since a rotation angle of the stay 16 is smaller than a rotation angle of a rear frame 3, the stay 16 is provided with a stay hooking screw idle running hole 15, while the rear frame 3 is provided with a stay rotation stop screw idle running groove 6.SELECTED DRAWING: Figure 1

    【課題】デザイン性を損なわずに輪行用補助輪を折りたたみ自転車に装着する目的を、最小の部品点数で、折りたたみ方の簡易性と軽量性を損なわずに可能とする。【解決手段】ステー16の蝶ネジ移動穴始端19へ補助輪17を蝶ネジ20で固定し、ステー16のステー回転軸穴13と前後フレーム連結ピポット4へ回転軸12を通して、ステー16を固定する。また、回転軸12を緊結してもステー16が稼働できる分のクリアランスに、ステー16の厚さ分を足した段を回転軸12へ設ける。また、リアフレーム3の回転角度よりステー16の回転角度の方が小さいのでステー16にステー引っかけビス空走穴15とリアフレーム3にステー回転止めビス空走溝6を設ける。【選択図】図1
