Claims

[Claim 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 end cap protruding inward from the lower end surface of the slider main body and slidingly contacting the side surface of the guide rail. A dustproof structure for a linear motion guide bearing device including an under seal, wherein mounting holes are formed near both ends of the under seal in the axial direction, and an edge of the under seal is formed on a lower end surface of the end cap. A dust-proof structure for a linear guide bearing device, characterized in that a notch recess in the axial direction having an inclined surface that bites into the recess, and a protrusion projecting from the recess and fitting into the mounting hole of the under seal are formed.
