<p>PROBLEM TO BE SOLVED: To provide a technology capable of efficiently generating power in a power generator using a piezoelectric element.SOLUTION: A power generator 100 includes: a tuning-fork type vibrator 10 having two vibrators 12, 14 which face each other; an eccentric weight 20 which may rotate relative to the tuning-fork type vibrator 10 and flips at least one of the two vibrators 12, 14 through rotary movement; and piezoelectric elements 40A, 40B which are attached to the tuning-fork type vibrator 10. A rotation axis O of the rotary movement of the eccentric weight 20 is positioned between the two vibrators 12, 14.</p> |
