Beschreibung
Zusammenfassung:	An object of the present invention is to provide a power generating device which makes it possible to easily generate electric power in a rotating system, such as a wheel including a tire, without impairing the performance and reliability of the rotating system. In the case where the power generating device 10 is mounted to a rotating body such as a tire, the direction of gravity applied to a weight 113 is changed with the rotation of the rotating body to cause beams 111 to be deflected, so that the positions of the deflected beams 111 and the weight 113 are fluctuated in synchronization with the period of the rotation to cause the position of a coil 121 to be displaced. Thereby, the weight 113 is vibrated in the vertical direction in synchronization with the period of the rotation of the rotating body to change the magnetic flux density crossing the coil 121. As a result, AC electromotive forces are generated in the coil 121 to enable electric power to be generated.
