PROBLEM TO BE SOLVED: To provide a linear motion device securing a smooth slide of a slider by surely absorbing this deformation even if any deformation is generated on a movable section. SOLUTION: The linear motion device 1 comprises: a plurality of guide rails 12, 13 arranged in parallel and in line with a fixed internal; a plurality of sliders 22 wherein at least one or more sliders moving on each of the guide rails 12, 13 are arranged on the plurality of guide rails 12, 13; a movable section 80 which bridges the plurality of guide rails 12, 13 and is movable along the plurality of guide rails 12, 13 by being supported by the plurality of sliders 22, and a plurality of first bearings 30 which are respectively arranged between the other slider 22a excluding one slider 22d among the plurality of sliders 22 and the movable section 80 and rotatably support the movable section 80 and the other slider 22a in such a manner that they can move straight in the bridge direction of the movable section 80.
