To abolish a configuration for press fitting of a hub dynamo to a wheel, thereby achieving reduction in a maintenance cost.SOLUTION: A wheel 10 with hub dynamo comprises: a hub insertion part 15 which is provided on a wheel 11 to accommodate a hub dynamo 20, and in and from which the hub dynamo 20 can be inserted and removed from only one side in a central axis O direction of a hub shaft 25; a circumferential direction engagement part 41 which has a concave part 18, which is formed in an inner peripheral surface 15f of the hub insertion part 15, and a convex part 28 which is formed on an outer peripheral surface 21f of a hub shell 21, and so engages the hub insertion part 15 and the hub shell 21 as to be unrotatably in a circumferential direction around the hub shaft 25 by engagement of the concave part 18 and the convex part 28; a positioning part 42 which defines a position in the central axis O direction of the hun shaft 25 of the hub shell 21 which has been inserted in the hub insertion part 15; and a restraining part 43 which restrains movement of hub shell 21, which has been inserted in the hub insertion part 15, to the other O side in the central axis O direction.SELECTED DRAWING: Figure 2
【課題】ハブダイナモをホイールに圧入する構成を廃し、メンテナンス費用の低減を図る。【解決手段】ハブダイナモ付き車輪10は、ホイール11に設けられてハブダイナモ20を収容し、ハブ軸25の中心軸O方向の一方P側からのみハブダイナモ20が挿抜可能とされたハブ挿入部15と、ハブ挿入部15の内周面15fに形成された凹部18、及びハブシェル21の外周面21fに形成された凸部28を有し、凹部18と凸部28とが係合することでハブ挿入部15とハブシェル21とをハブ軸25周りの周方向に回転不能に係合する周方向係合部41と、ハブ挿入部15に挿入されたハブシェル21のハブ軸25の中心軸O方向における位置を規定する位置決め部42と、ハブ挿入部15に挿入されたハブシェル21が中心軸O方向の他方Q側に移動するのを拘束する拘束部43と、を備える。【選択図】図2
