PROBLEM TO BE SOLVED: To enhance the alternating magnetic flux density generated in an output coil, improve the generating efficiency and increase the generating output by constituting a rotating weight wheel, a rotor shaft and a rotor pinion by use of a nonmagnetic body. SOLUTION: A generating device 10 is thinned by housing a disc-like rotor 30 in a plate stator 14 so as to be capable of being housed in a wrist watch device. A rotor transmitting gear 20 is superposed and arranged on the stator 14, and a part of a rotating weight wheel 12 is arranged so as to be protruded on the stator 14. Each of a rotor shaft 31, a rotor pinion 32, the rotor transmitting gear 20, a rotor transmitting shaft 21, a rotor transmitting pinion 22, and the rotating weight wheel 12 are formed of nonmagnetic body such as stainless or ceramic. Thus, the leak magnetic flux is reduced to increase the alternating magnetic flux density obtained by an output coil 15, and a generating device with high generating quantity can be provided. Therefore, a portable electronic device can be provided by use of this generating device. |
