Abstract
The under seal of this linear rolling guide unit comprises a pair of L-shaped under seal members that are bent and engaged together. The under seal members can be positioned relative to each other by engaging the engagement projections and the engagement recesses. Because the under seal members can be moved relative to each other in the longitudinal direction, if there are dimensional errors in the overall length of the slider in the longitudinal direction, they can be offset by adjusting the overall length of the under seal. In this way, the elongation and contraction due to thermal expansion and external forces are accommodated. The under seal is secured to the end surfaces of the end caps, not the underside of the slider, so that even when the dimension H.sub.1 between the base on which the track rail is installed and the slider's underside is small, the under seal can be easily and firmly fixed.
