In a lifting drive mechanism, first and second masts extend in the vertical direction. A lift platform is configured to be lifted or lowered along the first and second masts. A hanging belt includes a first end fixed to an upper portion of the lift platform and a second end fixed to the lower portion of the lift platform. An upper pulley supports the hanging belt. A driving pulley moves the hanging belt in a positive direction and a negative direction. An idler pulley is arranged in front of, in back of, or on both side of the drive pulley. A lower pulley is lower than the upper pulley and supports the hanging belt. A supporting member is pivotable around a fulcrum spaced away from a rotation center of the lower pulley in the horizontal direction, and is fixed. The supporting member includes a first end extending from the fulcrum in the horizontal direction and supporting the lower pulley such that the lower pulley is pivotable.
