PROBLEM TO BE SOLVED: To maintain the original service life of a linear guide device by effectively feeding a lubricant into a slider to suppress insufficient lubrication, and to prevent the lubricant from being fallen from a guide rail. SOLUTION: This linear guide device comprises the guide rail 1 extended in the axial direction and the slider 2 supported by the guide rail in a relatively movable manner along the axial direction, and moves the guide rail 1 in the axial direction while fixing the slider 2. A lubricant feed hole 18 is opened in a nozzle head 16 which is fitted to the guide rail 1 and integrally moved with the guide rail 1 in the axial direction, a through hole 19 communicated with the lubricant feed hole 18 is opened in the guide rail 1, and the lubricant is fed into the slider 2 via the lubricant feed hole 18 and the through hole 19.
