Claim:
A linear guide device including a guide rail, a slider main body having rolling element raceway surfaces opposing to rolling element raceway surfaces formed on the guide rail along the longitudinal direction of the guide rail, end caps each having rolling element direction changing channels in communication with a rolling element load rolling channel formed between both of rolling element raceway surfaces of the guide rail and the slider main body and in communication with rolling element return channels perforated through the slider main body along the longitudinal direction of the guide rail, a plurality of rolling elements that roll through the rolling element load rolling channel, the rolling element return channel, and the rolling element direction changing channel along with the relative linear motion of a slider comprising the slider main body and the end caps, and a plurality of separators each interposed between adjacent two rolling elements among the plurality of the rolling elements, in which the end cap has through-holes for assembling the rolling elements and the separators from the outside of the slider into the rolling element return channel.
