ABSTRACT:
A linear guide apparatus provides a guide rail extending axially and including a first rolling element groove formed on a side surface; a slider fitted with the guide rail and including a sleeve portion and a second rolling element groove formed on an inner side surface of the sleeve portion, the second rolling element groove of the slider confronting the first rolling element groove of the guide rail; and an under seal attached to a lower portion of the sleeve portion of the slider and projected from the inner side surface of the sleeve portion to slidingly contact with a surface of the guide rail, the under seal including a first projection arranged at an outer edge portion of a width of the under seal, the width being orthogonal to an axial direction of the under seal, the first projection having resiliency for pressing an inner edge portion of the under seal onto the guide rail. The under seal can be attached to the slider correctly without making displacement to ensure a proper seal margin.
