Abstract
An air jet type linear guide way contains an air chamber in the sliding block for injecting pressurized air therefrom along the track way so as to forcibly blow junks such as wastes, powder dust, or oil scales away before passing of the slide block assembly therefore no fear of infringement of contaminative foreign materials into the main structure of the linear guide way assembly that causes severe injury to its performance. The device of this invention will be well-suited for using in high contaminated working environments such as carpentry, stone cutting, or textiles and dyeing engineering where powder dusts are usually pervading in the air.
