Claims

[Scope of utility model registration request]

an external rotary dynamo that generates electricity by rotating in pressure contact with a tire tread surface; a mounting member having a mounting portion to the bicycle body; an arm member having a latching portion above the pivot portion; a coil spring for raising and lowering a tire that is wound around the pivot shaft and biases the arm member in a direction to press the arm member against the tire tread surface; A cam member that is supported by a mounting shaft on the member and has one end that can freely engage and disengage from the latching portion and that separates the dynamo from the tire tread surface in the engaged state, the cam member corresponding to one end of the coil spring. A bicycle power generating device characterized in that an exposed screw groove is provided on the mounting shaft, and one end of the coil spring is abutted and locked in the screw groove.
