ABSTRACT:
A linear movement guide bearing includes a guide rail and a slider straddling the guide rail for movement in an axial direction through rolling of balls interposed between the guide rail and the slider. A pair of under seals are attached to lower surfaces of the slider so that inner edges of the slide are slidably in contact with the side surfaces of the guide rail. Each under seal has elastic projection portions at axial opposite ends which protrude vertically toward the lower surface of the slider. Each elastic projection portion is formed by a forked elastic projection having two projection pieces whose free ends are expanded outwardly. Hook-like holding projections are formed on the free ends of the two projection pieces and protrude outwardly therefrom. The slider has vertical apertures formed in the lower surface for fitting the forked elastic projections thereinto and has through bores respectively formed orthogonal to the vertical apertures. When the forked elastic projection is fully fitted into the vertical apertures, the hook-like holding projections are engaged with the through bore to hold the forked elastic projection.
