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 devicein which a pair of work-piece lifting chainsrespectively fed movably forward and backward by a pair of regularly/reversely rotatable driving sprocketswhile being sandwiched by the sprockets includes flexing suppression membersdisposed oppositely to each other, and each of these flexing suppression memberscomprises a number of blocksdisposed at mounting intervals of two times the chain pitch P on a drawing side of the work-piece lifting/lowering chainand a lifting/lowering support barof 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 chainso that the flexing suppression membersare engaged with each other to lift or lower a work-piece in a chain's upright state of the fed chain.
