To allow a rear end to be stored between a top tube and a down tube by its being folded around a horizontal rotation shaft inclined to the down tube and fixed to a seat at a distance from a connection.SOLUTION: A folding means in which a seat 14 to which a horizontal rotation shaft 24 is fixed is separated from a down tube 3 and moved back and forth in the direction of a connection 27 to separate and connect recessed and projecting junctions 11, and the seat 14 is rotated around a quick release 15 to change a direction, includes: a lock button 16 that is attached to the down tube 3 by the quick release 15 and moves along a groove 20 set so as to be directed to a point P where a rear end 8 thereof is stored between a top tube 2 and the down tube 3; and an upper arm 22 and a lower arm 23 that guide the seat 14 by an oval hole 21 for passing the quick release 15 therethrough and connects the down tube 3 and the horizontal rotation shaft 24 at a distance from the connection 27; wherein the rear end 8 is stored between the top tube 2 and the down tube 3.SELECTED DRAWING: Figure 1

    【課題】 ダウンチューブに対して傾斜し接続部から離して台座に固定された横回転軸で折りたたむことで、リアエンドをトップチューブとダウンチューブの間へ格納可能とする。【解決手段】 横回転軸24を固定した台座14をダウンチューブ3から切り離して接続部27の方向へ前後することで凹凸接合部11の分離と接続を行い、クイックリリース15を中心に台座14を回転させることで方向変換を行う折りたたみ手段において、クイックリリース15でダウンチューブ3へ装着され、そのリアエンド8がトップチューブ2とダウンチューブ3の間へ格納できる位置P点へ向かうように設定された溝20に沿って移動するロックボタン16とクイックリリース15を通す楕円穴21に随って台座14を誘導し、かつダウンチューブ3と横回転軸24を接続部27から間隔を離して繋ぐ上腕22と下腕23を備え、リアエンド8をトップチューブ2とダウンチューブ3の間へ格納する。【選択図】図1
