Abstract:
PROBLEM TO BE SOLVED: To provide a power generator capable of generating a required electric power irrespective of the operation mode.SOLUTION: A power generator 100 having a button 1a capable of performing press-down operation includes: a power generation part 1 which is capable of generating electric power by means of electromagnetic induction when the button 1a is pressed down a predetermined amount; a press member 2 for pressing the button 1a; an operation member 3 for pressing the button 1a via the press member 2; and a limit part 4 which comes into a contact with the press member 2 to limit the press member 2 from pressing the button 1a until a predetermined pressing force PP1 is applied. The operation member 3 includes a first elastic member 3a for imparting a force to press the press member 2 toward the power generation part 1 to press the press member 2 via the first elastic member 3a. The predetermined pressing force PP1 is arranged to be larger than a repulsion force which is generated when the first elastic member 3a pressed by a predetermined amount.
