Abstract
A dust seal device used with a linear guide apparatus includes a pair of side seals respectively fixed to front and rear end surface of end caps and a pair of under seals respectively removably attached to lower surfaces of side walls of a slider. Each side seal has an inverted U-shape with a pair of bent pieces formed by bending lower portions of both leg portions of each side seal inwardly at right angles in an axial direction so as to cover the lower end surfaces of one end cap. Each side seal also has projections formed by respectively bending lateral side portions of the pair of bent pieces further upwardly to constitute positioning and under seal fall-off preventing projections. Each under seal is of a rectangular strip shape having a length substantially equal to that of the slider, including the thickness of the end caps. Each under seal is attached to the slider by inserting each under seal between the bent piece and the lower end surface of the end cap. The lateral movement of the under seal is prevented by the positioning and under seal fall-off preventing projections.
