　　　　　　　　　　　　　−[Claims for Utility Model Registration] 1. A track rail having a trapezoidal cross section and extending in the shape of a rail, and a sliding table having a recess with a trapezoidal cross section that fits the track rail and covering the track rail. Gothic arch-shaped ball transfer grooves are formed in two stages on the inclined outer surface of the track rail and the inclined inner surface of the hanging part of the sliding table, each at an angle of approximately 45° to the inclined surface. In the linear guide device according to the present invention, at least a first load support line connects a contact point between the upper ball transfer groove and the ball accommodated therein, and a lower ball rolling groove and the ball accommodated therein. A linear guide device characterized in that either one of the second load support lines connecting the contact point with the second load support line is slightly rotated in a vertical plane in a counterclockwise direction or a clockwise direction. 2. The linear guide device according to claim 1, wherein the first load support line and the second load support line are rotated by the same angle in opposite directions. 3. The linear guide device according to claim 2, wherein the first load support line is rotated counterclockwise and the second load support line is rotated clockwise.
