An anti-dust structure for a sliding block of a linear guideway comprises a sliding block and a flexible anti-dust strip. A positioning groove is formed in the inner surface of the sliding block and located correspondingly to the upper steel ball groove. The flexible anti-dust strip has a plurality of lip portions that protrude out of the positioning groove, and the lip portions come into contact with the top surface of the rail. In this way, the flexible anti-dust strip can scrape off the grease and dust accumulated on the top surface of the rail at all times, preventing the dust and grease entering the upper steel ball groove via the top surface of the rail, and thus obtaining a better anti-dust function and ensuring the service life of the linear guideway.
