Claims

[Claims for Utility Model Registration] (1) A long guide rail having 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 loosely fitted into the guide rail, and the guide rail and slider are axially opposed to each other through the rolling of a large number of rolling elements inserted into the rolling grooves of both the rolling elements. An under seal device for a linear motion guide bearing, in which an under seal that is in sliding contact with a side surface of the guide rail of a movable linear motion guide bearing is attached so as to protrude inward from a lower end surface of a sleeve portion of the slider, the under seal At both axial ends of the slider, bifurcated protrusions that open in a V-shape and can be elastically deformed in directions approaching each other are provided to protrude toward the lower end surface of the slider, and both axial ends of the lower end surface of the slider are provided. The part is provided with a vertical hole into which the two-pronged protrusion of the under seal fits, and a through-hole that is perpendicular to the vertical hole and passes through the sleeve part of the slider.
One of the projections of the prong is elastically deformed within the vertical hole to urge the under seal toward the side surface of the guide rail, and the side edge of the under seal is in sliding contact with the guide rail. Under seal device for dynamic guide bearings. (2) The underseal device for a linear motion guide bearing according to claim 1, wherein a locking protrusion that can be accommodated in the through hole is provided at the tip of the two-pronged protrusion of the underseal. (3) The under seal device for a linear motion guide bearing according to claim (1) or (2), wherein the locking protrusion is formed in a hook shape. (4) The under seal device for a linear guide bearing according to claim (1) or (2), wherein the locking protrusion is formed in an arc shape.
