PROBLEM TO BE SOLVED: To provide a grounding potential supplier for a hub dynamo that can easily use a one-wire type hub dynamo attached to a frame together with a wheel as a two-wire type hub dynamo without attaching/detaching the wheel, and realizing the positional relationship between a power source terminal and a grounding terminal in which the wiring work can be easily executed even to any kind of hub dynamos.SOLUTION: A grounding potential supplier 6 includes a flat attaching plate 50 which is attached by an outer surface of a fork end 4 and an inner surface of a fixing nut 17 directly, or indirectly via a conductive member such as a washer 18 for the fixing nut or the like, and electrically connected to a hub shaft 16 directly or indirectly via the fixing nut 17, a grounding terminal 54 which is electrically connected to the attaching plate 50 to supply the grounding potential of a hub dynamo 5 to an electric apparatus, and positioning parts 52, 53 which are fixed to the attaching plate 50 to position the attaching plate 50 with respect to the fork end 4. |
