PROBLEM TO BE SOLVED: To secure an expected power generation amount for a plurality of input frequencies without requiring the additional arrangement of an amplitude regulation member in a vibration power generation device configured to generate an induction electromotive force while utilizing vibration.SOLUTION: A movable-side unit 40 is configured to be abutted to a stationary-side unit 20 when its amplitude becomes a maximum allowable amplitude. In that case, a first protrusion P1 is formed on one end face of the movable-side unit 40, and a third protrusion P3 is formed at a position laterally dislocated from the first protrusion P1, on the other end face. On one end face 20a of the stationary-side unit 20, on the other hand, a second recess C2 is formed that can be engaged with the first protrusion P1 and on the other end face 20b, a fourth recess C4 is formed that can be engaged with the third protrusion P3. By inverting the movable-side unit 40 from such a state, the third protrusion P3 and the first protrusion P1 are abutted to general portions of the one end face 20a and the other end face 20b of the stationary-side unit 20, and the maximum allowable amplitude is reduced from Am0 to Am1. |
