To effectively control vibration of a suspended object and reduce a size of an insertion hole bored in a ceiling material located below a slab from which the suspended object is suspended.SOLUTION: A suspended object vibration control structure 100 includes: a ceiling material 20 formed with an insertion hole 22 while having an interval below a slab 10; a rigid bar 110 inserted through the insertion hole 22 and having a lower end part 110A to which a lighting fitting 50 is connected; a support mechanism 150 for supporting the rigid bar 110 so as to oscillate about an intermediate part 110C between the lower end part 110A and an upper end part 110B of the rigid bar 110 as the rotation center thereof; and a damper 120 for damping oscillation of the rigid bar 110.SELECTED DRAWING: Figure 1 【課題】効果的に吊物を制振し且つ吊物が吊られたスラブの下の天井材にあける挿通孔を小さくする。【解決手段】吊物制振構造１００は、スラブ１０の下に間隔をあけて設けられ挿通孔２２が形成された天井材２０と、挿通孔２２に挿通し下端部１１０Ａに照明器具５０が連結された剛棒１１０と、剛棒１１０の下端部１１０Ａと上端部１１０Ｂとの間の中間部１１０Ｃが回転中心として揺動するように剛棒１１０を支持する支持機構１５０と、剛棒１１０の揺動を減衰させるダンパー１２０と、を備えている。【選択図】図１
