To provide a compact lifter device, which can attain a work-piece's lifting/lowering operation in a stable supporting state and can reduce the parts number and an assembly load. A lifter device 100 in which a pair of work-piece lifting chains 130, 130 respectively fed movably forward and backward by a pair of regularly/reversely rotatable driving sprockets 120, 120 while being sandwiched by the sprockets includes flexing suppression members 140, 140 disposed oppositely to each other, and each of these flexing suppression members 140, 140 comprises a number of blocks 141 disposed at mounting intervals of two times the chain pitch P on a drawing side of the work-piece lifting/lowering chain 130 and a lifting/lowering support bar 142 of a length corresponding to a chain's upright state, disposed on a feeding side continued to the drawing side of the work-piece lifting/lowering chain 130, so that the flexing suppression members 140, 140 are engaged with each other to lift or lower a work-piece in a chain's upright state of the fed chain.
