PROBLEM TO BE SOLVED: To provide a vibration power generator of novel structure capable of achieving high efficiency power generation stably, and to provide a floor damping structure and a vibration detector using the same.SOLUTION: In a vibration power generator 10 for converting the vibration of a vibration member 60 into electricity, a first vibration system 12 of cantilever structure where a first mass member 18 is attached to the distal end of a first leaf spring 16 is provided, and a damping part for reducing the vibration of the vibration member 60 is constituted of the first vibration system 12. Meanwhile, a second vibration system 14 of cantilever structure where a second mass member 56 is attached to the distal end of a second leaf spring 54 is provided, and a power generation part for generating power when vibration is inputted by the second vibration system 14 is constituted by attaching the proximal end of the second leaf spring 54 to the first vibration system 12, and attaching a power generation element 58 to the second leaf spring 54. Furthermore, the attachment position of the second leaf spring 54 to the first vibration system 12 is closer to the distal end side than the proximal end of the fixing part of the first leaf spring 16 and first mass member 18 in the longitudinal direction of the first leaf spring 16.SELECTED DRAWING: Figure 3 【課題】高効率の発電を安定して実現し得る、新規な構造の振動発電装置と、それを用いた床制振構造体および振動検出装置を、提供すること。【解決手段】振動部材６０の振動を電気に変換する振動発電装置１０であって、第一の板ばね１６の先端部に第一のマス部材１８が取り付けられた片持ち構造の第一の振動系１２を設けて、第一の振動系１２によって振動部材６０の振動を低減する制振部を構成する一方、第二の板ばね５４の先端部に第二のマス部材５６が取り付けられた片持ち構造の第二の振動系１４を設けて、第二の板ばね５４の基端部を第一の振動系１２に取り付けると共に、第二の板ばね５４に発電素子５８を取り付けて、第二の振動系１４によって振動入力時に電力を生じる発電部を構成する。更に、第二の板ばね５４の第一の振動系１２への取付位置を、第一の板ばね１６の長さ方向で第一の板ばね１６と第一のマス部材１８の固定部分の基端よりも先端側とした。【選択図】図３
