Claims

[Scope of Claim for Utility Model Registration] An extended guide rail that has a substantially U-shaped cross section and has a single axial ball rolling groove at symmetrical positions on both inner surfaces; a slider fitted loosely so as to be movable in the axial direction through the rolling of a large number of balls, the slider having ball rolling grooves on both sides facing the ball rolling grooves of the guide rail; and a ball circulation member that is fitted into the slider body and has a ball circulation path therein that communicates with the ball rolling groove, wherein the bottom surface of the guide rail further includes: at least 1
A ball rolling groove is formed in the axial direction of the strip, and a ball rolling groove opposite to the ball rolling groove is formed on the outer surface of the bottom side of the guide rail of the slider body, and the inside of the ball circulation member of the slider is formed with a ball rolling groove opposite to the ball rolling groove. A lightweight type, characterized in that a ball circulation path communicating with the ball rolling groove is formed, and each of the ball rolling grooves is formed as a single arc having a radius of curvature larger than the ball radius. Linear guide device.
