To provide a lifting device that prevents a lifting member from moving from a predetermined position even if fluid is discharged from a valve when an excessive amount of fluid is supplied in a lifting device using fluid.SOLUTION: A lifting device 1 includes: a fluid supply source 2； a drive mechanism 3 having a drive part 31； a lifting member 4； a supply passage 5； a discharge passage 6； a discharge valve 7； an operation part OP1； a connection member 9 for connecting the discharge valve 7 and the operation part OP1 to each other, which moves by an operation of the operation part OP1: and a regulation mechanism 8 for regulating the movement of the lifting member 4. The regulation mechanism 8 includes a regulation member 81 that moves between a regulation position for regulating lowering of the lifting member 4 and a retreat position for permitting the movement of the lifting member 4 from the lower side to the upper side, and an auxiliary member 82 for moving the regulation member 81 according to the movement of the connection member 9.SELECTED DRAWING: Figure 3【課題】流体を用いた昇降装置において、過剰な流体が供給された際に弁から流体を排出しても、昇降部材が所定の位置から移動しない昇降装置を提供すること。【解決手段】昇降装置１は、流体供給源２と、駆動部３１を有する駆動機構３と、昇降部材４と、供給路５と、排出路６と、排出弁７と、操作部ＯＰ１と、排出弁７と操作部ＯＰ１とを繋ぎ、操作部ＯＰ１の操作によって移動する連結部材９と、昇降部材４の移動を規制する規制機構８とを備え、規制機構８は、昇降部材４の降下を規制する規制位置と昇降部材４が下側から上側へと移動するのを許容する退避位置との間を移動する規制部材８１と、連結部材９の移動に応じて規制部材８１を移動させる補助部材８２とを有している。【選択図】図３
