To provide an auxiliary wheel which realizes a secure and safe bicycle which can travel during a long time even at an extremely low speed equal to or less than a walking speed in a current road situation such that there is a lot of danger such as multiple side-by-side people and bicycles facing each other.SOLUTION: An L-shaped support rod 21, to a horizontal tip of which an auxiliary wheel 70 is fitted, and a horizontal tip of other L-shaped support rod 22 are rigidly connected, vertical upper half parts of these L-shaped support rods are so stored in external cylinders 15, 16 as to be slidable in a vertical direction, the same is fixed to a base plate, thereby forming an auxiliary wheel device assembly 100, and the assembly is assembled to a rear axle part. On the other hand, a hand-operated stand 40, which has a cushioning cylinder 50 at an upper end of the L-shaped support rod 22 and has a pressure reception surface at an upper part of the cushioning cylinder 50, and regulates upward movement of the L-shaped support rod, is added, and thus, bearing power is applied to the auxiliary wheel 70, and upward movement of the auxiliary wheel is controlled.SELECTED DRAWING: Figure 1
【課題】複数の横並びの人、対向する自転車など危険が山積して、気の抜けない現在の道路事情において、歩行速度以下の極低速でも長時間走行できる安心・安全自転車を実現する補助輪装置を提供する。【解決手段】水平先端部に補助輪70を取付けたL字形支持棒21と他のL字形支持棒22の水平先端部を剛結し、それらのL字形支持棒の垂直上半部を外筒15、16内に上下方向に摺動可能に収納し、それを基板に固定して補助輪装置組立体100となし、後車軸部に組付ける。一方、前記L字形支持棒22の上端に緩衝筒50と、該緩衝筒50の上部に受圧面を有し前記L字形支持棒の上方移動を規制する手動式スタンド40を付加し、補助車輪70に支持力を付与し該補助車輪の上方移動を制御する。【選択図】図1
