PROBLEM TO BE SOLVED: To provide a linear guide device with a mechanism constructed for smoothly moving a slider without using a ball screw. SOLUTION: The linear guide device 1 comprises a linear rail 10 and the slider 20 free to move on the rail 10. The rail 10 is formed with a flat rail face 10a extending linearly. The slider 20 is provided with an input shaft 3 disposed to rotate by drive of a servo motor M and a roll shaped idler 5 which is disposed in pressure contact with the input shaft 3 and the rail face 10a through intervention of traction oil and is constructed to rotate following rotation drive of the input shaft 3 and to roll on the rail face 10a. Thereby, the idler 5 can rotate by the rotation of the input shaft 3, the slider 20 can self-advance on the rail 10 and the ball screws is dispensed with. COPYRIGHT: (C)2007,JPO&INPIT
