PROBLEM TO BE SOLVED: To provide a bicycle hub which easily secures electric continuity between a hub shaft and a hub shell, an electric power supply device for a bicycle, and an electric power system for a bicycle.SOLUTION: A hub dynamo 180 has: a hub shell 182 which is supported so as to rotate relative to a hub shaft 184; and a first bearing 192 provided between the hub shell 182 and the hub shaft 184. The first bearing 192 includes: a metallic outer ring 250 which rotates integrally with the hub shell 182; and a metallic inner ring 248 which is supported by the hub shaft 184 and does not rotate integrally with the hub shell 182. The outer ring 250 and the inner ring 248 are electrically connected by a plurality of metallic rolling elements 252.SELECTED DRAWING: Figure 26

    【課題】ハブシャフトとハブシェルとの間の導通を確保しやすい自転車用ハブ、自転車用電力供給装置、および、自転車用電動システムを提供する。【解決手段】ハブダイナモ180は、ハブシャフト184に対して相対回転可能に支持されるハブシェル182と、ハブシェル182とハブシャフト184との間に設けられる第1の軸受192とを有する。第1の軸受192は、ハブシェル182と一体的に回転する金属製の外輪250と、ハブシャフト184に支持され、ハブシェル182とは一体的に回転しない金属製の内輪248とを含む。外輪250と内輪248とは、金属製の複数の転動体252により電気的に接続される。【選択図】図26
