PROBLEM TO BE SOLVED: To provide a linear guide device capable of preventing a roller from being skewed, even when a cage floats up from a slider body. SOLUTION: This linear guide device includes the cage 20 having four lines of rolling element circulation routes formed to go upwards along with separation of a rotation axis of the upper line roller 8 from a guide rail, and to go upwards along with separation of a rotation axis of the lower line roller 8 from the guide rail, and a raceway track flange 23 assembled in an inner face of the slider body, and for guiding an end face of the roller 8. The cage 20 is provided with the raceway track flanges 23 along both end faces of the rollers 8, the first chamfer parts 23m are formed in longitudinal both ends of the raceway track flange 23 provided on the upper side of the upper line rollers 8 and an underside of the lower line rollers 8, and the first chamfer part 23m is formed to make a longitudinal-directional length LM longer than a depth LD in the direction opposed to the end face of the roller 8.
