PROBLEM TO BE SOLVED: To provide a linear module equipped with a supporting device.SOLUTION: A screw supporting deice is equipped with a pedestal; two pivot seats; a screw; at least one guide rail; a moving platform; two supporting pedestals; a roll rotatably installed on the moving platform, and having at least one first roll and a second roll portion whose ring diameter is smaller than a ring diameter of the first roll portion; a uniting member which has two joint end portions respectively fixed on the two supporting pedestals, and a coupling bottom surface contacted with the second roll portion to be interlocked; and an outside cover body which has two outside cover body end portions respectively fixed to the two pivot seats, and a bottom surface of the outside cover body keeping the contact with the first roll portion. By this structure, mechanism is simplified, so that a purpose that a maintenance cost is decreased is attained, and simultaneously, a service life is extended. Furthermore, the outside cover body of a linear module is supported, thereby decreasing interferences between the outside cover body and the moving platform or the supporting pedestals of the linear module.SELECTED DRAWING: Figure 2 |
