PROBLEM TO BE SOLVED: To provide a screw driven carrying device having a reduced size as a whole by simplifying the construction to support and drive a screw shaft without deflecting the screw shaft even when a carrying distance is longer. SOLUTION: The screw driven carrying device is provided for carrying carried objects engaging therewith with the rotation of a screw shaft 110. The screw shaft 110 has both ends rotatably borne and an intermediate upwardly supported by a cylindrical guide roller 150 which can roll on the circumferential face. COPYRIGHT: (C)2010,JPO&INPIT
