PROBLEM TO BE SOLVED: To provide a carrying mechanism capable of carrying a carrying object while further surely absorbing an inclination in parallelism and flatness between a screw shaft and a slide rail. SOLUTION: A nut installing part 34 and a nut member 22 are superposed by respectively inserting a bolt 26 into a bolt hole 34A. The bolt hole 34A is formed as an elongate hole having a diameter larger than the bolt 26 and long in the direction orthogonal to the carrying direction X, and a play space R is constituted between the bolt 26 and the bolt hole 34A. A coil spring 28 is wound around the outer periphery of a screw body part 26A. The coil spring 28 is arranged between a screw head part 26B and the nut installing part 34, and energizes the nut installing part 34 toward the nut member 22. The nut installing part 34 can be relatively moved with the nut member 22 in a range of the play space R of the bolt hole 34A between the part and the nut member 22. COPYRIGHT: (C)2009,JPO&INPIT
