Claims

[Claims for Utility Model Registration] 1. A track rail having two outer surfaces facing each other line-symmetrically, and a recess having two inner surfaces facing the two outer surfaces, and extending along the outer surfaces. a sliding base slidably placed over the track rail; two grooves on each surface extending in the sliding direction of the sliding base at opposing positions on the two outer surfaces and on the two inner surfaces; In a linear guide device having a rolling element interposed between the corresponding grooves, the grooves have a Gothic arch groove shape, and the distance between the two grooves on each of the two outer surfaces and the two inner surfaces A linear guide device characterized in that the groove intervals of each of the above two grooves are different. 2. A utility model registration claim characterized in that the distance between the two grooves on the two inner surfaces of the sliding base is larger than the distance between the two grooves on the two outer surfaces of the track rail. The linear guide device according to scope 1.
