Summary:In a linear guide apparatus including a guide rail, a slider fitted movably to the guide rail, a plurality of rolling elements loaded to move the slider relative to the guide rail, and a seal device mounted on a side of the slider to seal a clearance existing between the guide rail and the slider, the seal device includes a reinforcement member that has a contact surface fixed to the slider and a recess formed in the contact surface to surround the outer surface of the guide rail, and a lubricant-containing polymer member that is fitted into the recess and has an inner sealing portion slidably contacting the guide rail and an outer surface opposed to the inner sealing portion and positioned at a predetermined clearance relative to the recess. The seal device assembling the lubricant-containing polymer member into the reinforcement member reduces a possibility of the occurrence of damage, cracking or other failures during fitting or use of the seal device.
