The present invention relates to a main drive device of a stacker crane, and applies a structure for linearly moving the body frame through a gear tooth engaging structure using a driving pulley and a timing belt, thereby driving a moving roller as in the prior art to straighten the body frame. Since it is not a moving structure, it is possible to accurately control the moving position of the body frame regardless of the slip phenomenon of the moving roller, so that even if the internal environment of the distribution warehouse is poor, the stacker crane can be operated stably and driven By applying a gear tooth meshing structure using a pulley and a timing belt, unlike normal rollers, mutual slippage is prevented in the relationship between the drive pulley and the timing belt, so the body is always in the correct position in proportion to the amount of rotation of the drive pulley by the drive unit Provided is a main driving device of a stacker crane capable of moving a frame.
