To provide a structure in which a power generation device is rocked, vibrated or rotated, continuous high power generation output is obtained only by rotating an inner permanent magnet in a ring-like passage, a device of long life is realized with low cost, maintenance is not required outdoors and self-power generation is performed for long time only by rotating wheels especially when it is attached to a spoke of the wheel of a bicycle and to provide a manufacturing method of the structure.
A hollow cylinder 101 in which a metal wire 102 is wound to an outer periphery in a coil shape and which has a curvature is arranged, and a housing having the hollow ring-like passage is constituted. The permanent magnet 104 is enclosed in the ring-like passage in a state where it can be rotated. When a plurality of the permanent magnets are enclosed, they repel each other. The housing is constituted and a whole is coated with resin, rubber and glass and an integrated structure is obtained.
