To provide a folding structure for efficiently reducing the size of a folding bicycle when it is folded and stored.SOLUTION: First and second components 1 and 2 having coil or cylindrical shapes having helical sliding surfaces 4 are arranged to face each other on the sliding surfaces 4, and pivotally connected by a pivotal shaft 3. When one of the first and second components 1 and 2 is operated in a circumferential direction, the sliding surfaces 4 of the first and second components 1 and 2 interfere with each other, and the operated component moves in an axial direction. Thus, interference between frames can be efficiently prevented during folding.SELECTED DRAWING: Figure 2

    【課題】折り畳み自転車において、折り畳み収納時の大きさを、効率よく小さくするための折り畳み構造を提供する。【解決手段】螺旋状の摺動面4をもったコイル形状又は円筒形状をそれぞれ有した第1・第2部品1・2は互いの摺動面4が向き合うように配置され、枢動軸3によって枢動可能に接続される。第1・第2部品1・2のどちらか一方を円周方向に作動させると、第1・第2部品1・2の互いの摺動面4が干渉し合い、作動させた部品が軸方向へ移動することによって、折り畳み時にフレーム同士の干渉を効率よく回避することが出来る。【選択図】図2
