Claims

[Scope of claim for utility model registration] (1) In a night light generator that generates electricity from the rotation of a bicycle wheel, the entire circumference of the wheel rim on the outer edge side from where the spokes are attached, or
Permanent magnet pieces are arranged alternately between N and S poles on a ring or desk board with the center of the wheel as the fulcrum.
A non-contact generator for a bicycle night light, characterized in that a fixed generator coil is disposed at a position facing the magnet piece. (2) It is characterized by a structure in which the fixed power generation coil can be freely selected from two mounting positions, one close to the rim-side permanent magnet piece and the other away from it, so that it can be switched between the power generation position and the non-power generation position. A non-contact generator for a bicycle night light according to Claim 1 of the Utility Model Registration Claim.
