SOLUTION: This wireless remote controller is made to vibrate by a user to operate a moment of couple at a rotary weight 9, and the weight 9 is rotated. This rotation is decelerated by a gear 10 and an intermediate gear 11, and then transmitted to a rotor 12. A stator 13 is disposed around the rotor 12, and fixed to a core 14. Here, coils 15-a, 15-b are wound in the same direction on the core 14, and rectifying diodes 16-a, 16-b are disposed so that phases of voltage waveforms of the coils 15-a, 15-b at 103 are deviated by 180 deg.. The waveform at 101 is an intermittent waveform, and the waveform at 102 is also an intermediate waveform. Since the waveform at 102 is deviated at a phase of 180 deg. with respect to that at the 101, the waveform at 103 is a composite waveform of the waveform at 103 and that at 102.
