PROBLEM TO BE SOLVED: To provide a jack handling device for vertical motion of furniture capable of preventing breakage of a jack, a jack operation device, a linkage body for linking a plurality of jacks or the like, by operating the jack more than necessary.SOLUTION: In a jack handling device X, two longitudinal notches 33 are formed on a handle insertion hole 32, and an upward inclination 34 is imparted to each notch 33 in the rotation same direction. Consequently, when furniture is lowered to a prescribed position, a handle 20 is deviated from the handle insertion hole 32, to thereby prevent application of force stronger than necessary.SELECTED DRAWING: Figure 6

    【課題】ジャッキを必要以上に作動させてジャッキやジャッキ作動装置、複数のジャッキを連動させる連動体等の破壊を防ぐ家具の上下動用ジャッキ操作装置を提供する。【解決手段】本発明のジャッキ操作装置Xは、ハンドル挿入孔32に縦方の切り欠き33を相対向して二箇所形成するとともに、該切り欠き33に回転同一方向に上向きの傾斜34を付してある。従って、家具が所定の位置まで降下したときにハンドル20がハンドル挿入孔32から外れて必要以上の力が掛からないようになっている。【選択図】図6
