PROBLEM TO BE SOLVED: To provide a power generator which can perform efficient power generation and has excellent durability.SOLUTION: A spoke 54 collides with a tongue piece part 11A of a power generation unit 11 during movement of a bicycle. An impact force in an arrow X direction acts on the tongue piece part 11A from the spoke 54 during the collision, and the power generation unit 11 is deformed greatly. After the collision, a restoration force in an arrow Y2 direction which is substantially opposite to the arrow X direction, is applied to a base material 21 and a piezoelectric film 22, and the base material and the piezoelectric film are greatly deformed. Then, the spoke 54 collides again with the tongue piece part 11A of the power generation unit 11, and the impact force in the arrow X direction acts thereon. Thereby, the deformation by the impact force and the deformation by the restoration force are repeated, and the power generation unit 11 performs efficient power generation.SELECTED DRAWING: Figure 7

    【課題】効率的な発電が可能であり、且つ、耐久性に優れた発電装置を提供することを課題とする。【解決手段】自転車の移動時には、スポーク54が発電ユニット11の舌片部11Aに衝突する。その衝突時には、スポーク54から舌片部11Aに矢印X方向の衝撃力が作用し、発電ユニット11は大きく変形する。その衝突後、基盤材21及び圧電フィルム22には、矢印X方向とは略反対である矢印Y2方向の復元力が働き、大きく変形する。その後、発電ユニット11の舌片部11Aへスポーク54が再度衝突し、矢印X方向の衝撃力が作用するため、衝撃力による変形と復元力による変形が繰り返され、発電ユニット11は効率的な発電を行う。【選択図】図7
