Claims

[Claims for Utility Model Registration] (1) A long guide rail with axial rolling grooves on both sides, and a rolling groove facing the rolling grooves of the guide rail. a slider disposed on an inner surface and straddled over a guide rail, and the guide rail and the slider move in the axial direction through the rolling of a large number of rolling elements inserted into both the rolling element rolling grooves. The linear motion guide bearing is capable of relative movement and has side seals on both end faces of the slider, and the side edge of the under seal that makes sliding contact with the side surface of the guide rail protrudes inward from the lower end face of the slider. In an underseal device for a linear guide bearing that is mounted on a linear guide bearing, an axially extending protrusion is formed at both axial ends of the underseal, and the protrusion of the underseal fits into a lower end surface of the side seal. An underseal device for a linear motion guide bearing, characterized in that a fitting hole is formed to accommodate the (2) At least one of the protrusions of the under seal is composed of two pronged angular protrusions that can be elastically deformed toward and away from each other, and a hook-shaped locking part is provided at the end of each angular protrusion. Claim (1) characterized in that
Under seal device for the linear motion guide bearing described. (3) The underseal device for a linear motion guide bearing according to claim 1 or 2, characterized in that an elastic coating layer that is in close contact with the side seal is provided on an axial end face of the underseal. (4) The underseal device for a linear motion guide bearing according to claim 1, wherein an elastic coating layer is provided on a side surface of the protrusion of the underseal that fits into the fitting hole. (5) The under seal device for a linear guide bearing according to claim 1, wherein one axial end of the under seal is integrally fixed to a side seal.
