A roller holder includes a number of rollers disposed in an outer holding device and partially extended out of the outer holding device and alternately disposed between the rollers and arranged in different direction relative to each other for engaging with different directions between two moving members and for facilitating the sliding movement between the two moving members. The outer holding device includes a number pairs of spacers disposed alternately relative to each other, and retained together with one or more flexible rods for retaining the rollers between the spacers. The spacers each include opposite curved recesses for rotatably receiving the rollers between the spacers.
