PROBLEM TO BE SOLVED: To provide a screw-driven carrying device which alleviates a maintenance burden and suppresses the occurrence of an adverse effect on other equipment due to wear powder by preventing the occurrence of wear and which realizes smooth transportation by reducing heat liberation, noise, vibrations or the like. SOLUTION: In a screw-driven carrying device 100, a roller 122 provided to a carrying truck 120 is engaged with a screw shaft 110 to be carried. The roller 122 has a tapered shape having a rotary shaft orthogonal to a rotary shaft of the screw shaft 110. The screw shaft 110 includes a wall surface 112 inclined so as to come into line contact with an outer peripheral surface of the roller 122. COPYRIGHT: (C)2011,JPO&INPIT
