PROBLEM TO BE SOLVED: To provide a linear guide device in a simple configuration capable of saving energy and space by efficiently discharging dust between a guide rail and a slider. SOLUTION: The linear guide device includes a guide rail 2, a slider 3, a rolling body 6 inserted between the rolling body rolling grooves 2a and 3a formed in the guide rail 2 and the slider 3, respectively, and a sucking means 10 for sucking dust between the guide rail 2 and the slider 3, the sucking means 10 including a penetrated cylindrical volume variable portion 11, a first check valve 12, and a second check valve 13. A negative pressure is generated by a change in the volume of the volume variable portion 11 owing to the slider 3 which is connected via the first check valve 12 to the volume variable portion 11 and slides relative to the guide rail 2, whereby the dust between the guide rail 2 and the slider 3 is discharged from the side of the second check valve 13.
