Claims

[Claims for Utility Model Registration] An extended guide rail with symmetrical axial ball rolling grooves on both sides, and a ball rolling groove on the side facing opposite to the ball rolling groove of the guide rail. A linear guide comprising a slider and a ball row made up of a large number of balls inserted into the opposing ball rolling grooves so as to be able to roll freely, and installed with an inclination that creates a difference in height between the ball rows on both sides of the guide rail. In the device, an oil supply port is provided on a lower outer surface of the slider, and an oil supply path extends from the oil supply port toward the opposite side, and from the oil supply path.
A pair of left and right branch oil passages are formed at both corners of the inner surface facing the upper surface of the guide rail, and the branch oil passages have an oil passage diameter closer to the oil filler port than the oil passage diameter farther from the oil filler port. A lubricating structure for a linear guide device characterized by a small diameter.
