PURPOSE: To provide an assist bicycle which achieves a very compact form when folded and enables easy folding work.CONSTITUTION: An assist bicycle includes: a center oblique pillar 3; a front pillar 1 comprising a front shaft pipe part 11 and a handle shaft part 12; a front fork 13; a connection support tool 2 having a pivotal connection part 23 which constantly connects a front pillar sandwiching part 21 with the center oblique pillar 3 and a detachable connection part 24 which is detachably connected; a handle 8; a rear fork 34; and a rear pillar 5 which is fixed to the center oblique pillar 3 in a standing state and a leaning state. When folding is completed, a rear shaft part 51 of the rear pillar 5 fixed to the center oblique pillar 3 in a forward leaning state is lifted upward so as to be in a vertical state to bring the center oblique pillar 3 into a vertical state with the rear shaft part 51, bring the center oblique pillar 3 and the rear pillar 5 into a V-shaped folded state, and bring the center oblique pillar 3 and the front pillar 1 into a folded state in which these pillars are folded in an inverted V-shape.SELECTED DRAWING: Figure 1

    【目的】折り畳み状態が極めてコンパクトで折り畳み作業を簡単にできるアシスト自転車とすること。【構成】中央斜め支柱3と、前軸管部11とハンドル軸部12とからなる前支柱1と、フロントフォーク13と、前支柱挟持部21と中央斜め支柱3と常時連結する枢支連結部23と脱着する脱着連結部24とを有する連結支持具2と、ハンドル8と、リアフォーク34と、中央斜め支柱3に起立状態と倒れ状態の固定状態とされる後支柱5とが備えられ、折り畳み完了のときには、中央斜め支柱3に対して前方側に倒れ状態で固定された後支柱5の後軸部51が垂直状となるように上方に持ち上げられることにより、後軸部51と共に中央斜め支柱3が垂直状となった中央斜め支柱3と後支柱5とはV字状の折り畳み状態となり、中央斜め支柱3と前支柱1とは逆V字状に折り曲げられる折り畳み状態となること。【選択図】 図1
