Claims

[Claims for Utility Model Registration] A long guide rail with axial ball rolling grooves on both sides, and a guide rail movably spanning over the guide rail and facing the ball rolling groove of the guide rail. A slider body having a ball rolling groove on an inner surface thereof and a through hole serving as a ball passage parallel to the slider body within the wall thickness, and a curved path that communicates the ball passage with the ball rolling groove. An end cap joined to the end of the main body, a number of balls rollably inserted into the ball rolling groove, and an under that protrudes inward from the lower end surface of the slider and slides into contact with the side surface of the guide rail. A dust-proof structure for a linear guide bearing device comprising a seal, wherein the under seal has both ends in the axial direction bent inward to form a U-shape, and the under seal is formed in a U-shape by bending both ends in the axial direction, and has a surface facing inward on the bent surface. A dust-proof structure for a linear motion guide bearing device, characterized in that a protruding engaging convex portion is provided, and a recess into which the engaging convex portion of the under seal fits is formed on the outer end surface of the end cap.
