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 |
