To provide an insert that allows mounting and tensioning of spokes in bicycle spoked wheels that are equal in structural strength and excel in aerodynamic behavior as compared with conventional wheels.SOLUTION: An insert 60 used in a rim 10 of a spoked wheel for a bicycle, comprises a first surface portion 61 that is configured to abut against an inner surface of the rim 10 at a spoke attachment hole 18 of the rim 10, a through hole 62 that extends along a longitudinal axis and is configured such that a spoke attachment element 40 passes therethrough, and a second surface portion 64 that is configured to abut against an enlarged head of the spoke attachment element. The insert 60 includes at least one holding element 50 that is configured to prevent the spoke attachment element 40 from moving along the longitudinal axis while the spoke attachment element 40 abuts against the second surface portion 64.SELECTED DRAWING: Figure 3
【課題】従来の車輪と比較して、構造強度が同等で、空気力学的挙動が優れた自転車用スポーク車輪において、スポークを取付けて張り渡すことができるインサートを提供する。【解決手段】自転車用スポーク車輪のリム10に用いられるインサート60は、リム10のスポーク取付孔18においてリム10の内側表面と当接するように構成された第1表面部分61と、長手方向軸に沿って延び、スポーク取付エレメント40が貫通するように構成された貫通孔62と、スポーク取付エレメントの拡大ヘッドと当接するように構成された第2表面部分64とを備えると共に、インサート60は、スポーク取付エレメント40が第2表面部分64と当接しているとき、スポーク取付エレメント40が長手方向軸に沿って移動することを防止するように構成された少なくとも1つの保持エレメント50を備える。【選択図】図3
