PROBLEM TO BE SOLVED: To provide a rolling guide device to reliably preventing the occurrence of a skew of rollers and enable an increase in rigidity of a linear motion guide device. SOLUTION: The rolling guide device is provided with a track rail 1 having roller running surfaces 1b, etc., and a roller circulation passage containing load roller running surfaces 4d, etc., corresponding to the roller rolling surfaces 1b and comprises a moving block 2 relatively movably assembled at the track rail 1, and a plurality of rollers 3, etc., aligned and contained and circulating along with relative movement of the moving block 2 with the track rail 1. The roller 3, etc., has a ratio of approximate 1.5<L/Da <approximate 3. By setting the approximate 1.5<L/Da , a fundamental statically rated load Co is increased compared with the same type number of a ball specification. Further, by setting L/D<approximate 3, a size of a gapΔL in the axial direction is not so strictly managed and the occurrence of the skew can reliably be prevented.
