PROBLEM TO BE SOLVED: To provide a stand which realizes easy upward lift of a heavy bicycle, such as an electric assist bicycle, allows fixation at a position suitable for operation, prevents falling out of a bicycle due to accidental improper operation, and allows smooth pull down of the bicycle on a position of a floor surface at the operation end.SOLUTION: There is provided a bicycle maintenance/assembling stand, which has a structure where a holding part may vertically move with a bearing on a main shaft vertically fixed relatively to the floor surface on a base body, and which is provided with a foot pedal on the holding part in order to provide positive pressure by compressing gas in a gas spring with an elevation type stand in which a holding pipe for holding the bicycle is movable vertically, so that strong power may be easily applied downwardly with body weight. The maintenance/assembling stand has one way fixing mechanism on a holding part of a beam shape for holding a bicycle engaged with the main shaft, where front/back surface contacting to main shaft of a lever or one surface fixes the holding part onto the main shaft with angular moment when the lever passing the main shaft is shifted down.SELECTED DRAWING: Figure 1

    【課題】電動アシスト自転車などの重量の有る自転車を上方向への移動を容易にし、作業に適した位置に固定可能にする物で、万一の誤操作などで自転車の落下を防止し、作業終了時に自転車を床面の位置に円滑に降下させる。【解決手段】自転車の整備・組立スタンドのおいて基体に床面に対して垂直に固定された主軸にベアリングなどで保持部が主軸に沿って上下に可動可能な構造として、保持部には自転車を保持する保持パイプをガススプリングにより上下動可能にした昇降式スタンドで、ガススプリングのガスを圧縮して与圧得るために足踏みペダルを設け体重により大きな力を下向きに加え易くした。主軸に勘合される自転車を保持する梁状の保持部には、主軸を貫通するレバーが下がるとレバーの主軸に接する前後面又は片面が回転モーメントにより保持部を主軸に固定する一方向固定機構を持った整備・組立スタンド。【選択図】図1
