Abstract
In a linear guide apparatus including an axially extending guide rail, a slider engaged with the guide rail, and a plurality of rolling elements loaded into the slider, the linear guide apparatus further includes a sealing device fixed to the slider in slidable contact with the guide rail for sealing a clearance existing between the guide rail and the slider, in which the sealing device includes a lubricant-containing polymer member formed of a synthetic resin containing a lubricant, and having a contact portion contacting with the guide rail to surround the guide rail, both wing portions, a connecting portion connecting the wing portions to be C-shaped substantially, and a pair of first recesses formed in the respective wing portions for fixing the lubricant-containing polymer member to the slider; a first plate member fitted to the lubricant-containing polymer member opposed to the slider; and a pair of first cylindrical members inserted to the respective first recesses.
