PROBLEM TO BE SOLVED: To provide a new washer that can eliminate bending caused in a hub spindle by an inexpensive component and further can uniformly eliminate the bending of the hub spindle even if any type of hub spindle is mounted, and provide a bicycle frame with the washer and a bicycle with them.SOLUTION: When a hub spindle is fixed to a frame end while the hub spindle is fitted in the U-shaped groove of the frame end of a bicycle, a protrusion to fill a gap between the hub spindle fitted in the U-shaped groove and the U-shape groove is provided in a washer overlapped on the frame end, and the thickness of the protrusion is set in the same thickness as the thickness of the frame end. Thereby, a pressure can uniformly be applied to the hub spindle when the hub spindle is clamped in the frame end, and therefore the bending of the hub spindle can be eliminated and the rotational performance of the wheel can be improved.SELECTED DRAWING: Figure 1

    【課題】安価な部品でハブ軸に生ずる撓みを解消することができ、しかも、どのような種類のハブ軸を装着しても、均等にハブ軸の撓みを解消することのできる新たなワッシャとそのワッシャを備えた自転車用フレームとそれらを備えた自転車を提供することを課題とする。【解決手段】自転車のフレームエンドのU字状溝にハブ軸を嵌めこんだ状態で前記ハブ軸を前記フレームエンドに固定するときに、前記フレームエンドに重ね合わせるワッシャに前記U字状溝に嵌め込まれたハブ軸と該U字状溝との間の隙間を埋める突起部を設け、該突起部の厚みを前記フレームエンドの厚みと同じ厚さに設定する。これにより、ナット等でハブ軸をフレームエンドに締め付ける際に、ハブ軸に均等に圧力を加えることができるから、ハブ軸の撓みを解消して、車輪の回転性能を改善することができる。【選択図】図1
