In a linear guide apparatus including a guide rail, a slider and a plurality of rolling elements, the apparatus further includes a seal device fixed to the slider in slidable contact with an outer surface of the guide rail for sealing a clearance existing between the guide rail and the slider, the seal device including a reinforcement plate and a lubricant-containing polymer member, the reinforcement plate having a first surface fixed to the end face of the slider and a second surface which is formed of polyolefinic synthetic resin, the lubricant-containing polymer member being formed of a polyolefinic polymer and a lubricant, and joined to the second surface of the reinforcement plate by one-piece molding. The linear guide apparatus can supply automatically the lubricant from the seal device to the rolling elements in the slider consistently over an extended period of time while reducing a possibility of the occurrence of damage, cracking or other failures because of the reinforcement plate.
