PROBLEM TO BE SOLVED: To provide a linear guide bearing device having high dust-proof effect improving sealing performance by removing fine foreign matters and by suppressing frictional heat and abrasion of a seal in sliding of the seal. SOLUTION: In this linear guide bearing device comprising a seal member 15 mounted on an axial end part of a slider 2 and slidably kept into contact with a guide rail 1 to seal the axial end part of the slider 2, the seal member 15 is composed of a porous felt material impregnated with a lubricant, and the plurality of seal members 15 are arranged in the axial direction of the slider 2 in such a state that densities of the seal members 15 are different from each other.
