Abstract:
The sealing performance by a side seal is improved by changing the sealing function of the side seal for a linear guide apparatus which includes, as constituting components, a seal member, a holder plate that holds the seal member, and a cover (a scraper) depending on its application of the side seal. Plural types of the seal members (1A to 1B) which have a difference in at least any one of the inclination, the material, the thickness, and the tip shape of lips (11a to 11f) are prepared as the seal members. Multiple numbers of the seal members among those seal members are appropriately selected, the same number of the covers and the same number of the holder plates are combined together to assemble the side seal.
