Claims

[Scope of utility model registration request]

a rail having a pair of upper and lower inclined load roller rolling surfaces on a protrusion formed on a side part; an upper member that straddles the upper part of the rail so as to surround the upper load roller rolling surface of the rail; a sleeve member fixed to a side portion of the member and hanging down so as to cover at least a lower load roller rolling surface of the rail, and the upper member has a rectangular load facing the upper load roller rolling surface of the rail. It has a roller rolling groove and a V-shaped roller return groove formed on the side surface of the upper member above the square load roller rolling groove, and the sleeve member has a square shape opposite to the lower load roller rolling surface of the rail. A load roller rolling groove, a lower V-shaped roller return groove formed on the lower edge diagonally below the rectangular load roller rolling groove, and a V-shaped roller return groove of the upper member facing the upper member. It has an upper V-shaped roller return groove formed on the joint surface, a number of rollers are housed between the upper and lower load roller rolling surfaces and the corresponding grooves, and the upper member and the sleeve member An angular roller linear guide device characterized in that the upper roller return groove is secured by beam welding except for the vicinity of the crowning portion of the groove end of the upper roller return groove.
