PROBLEM TO BE SOLVED: To provide a linear motion guide device which is enabled in acceleration feed or deceleration feed while avoiding the elongation of an axial length. ! SOLUTION: A linear motion table device comprises two ball screws 10, 20 which are arranged in parallel with each other. The first ball screw 10 comprises a first screw shaft 11 which is formed so that a screw groove 11a and a spline 11b are not overlapped on each other, a first nut 12, and a cylindrical member 13 which is guided by the spline 11b so as to be rotatable integrally with the first screw shaft 11, and attached to the first screw shaft 11 so as to be movable to an axial direction. The second ball screw 20 comprises a second screw shaft 21 which is arranged so as to be rotatable with respect to a base table 30 and to be movable to the axial direction, and a second nut 22. Furthermore, the linear motion table device comprises a nut housing 51 which comprises a rotation transmission mechanism 60 for transmitting the rotation of |
