PROBLEM TO BE SOLVED: To provide a roller guide in which supply of a lubricating agent to a raceway is performed stably, which is suitable even in the case of mounting a plurality of sliders on one guide rail. SOLUTION: Spherical surface rollers 3 are attached to four locations of a slider body 21 with roller shafts 4. A lubricating unit 5 is disposed between spherical surface rollers 3 opposed in the linear motion direction of the slider body 21. The lubricating unit 5 comprises a unit body 51, a lubricating component 52 composed of a lubricating agent-containing resin, a holder 53 of the lubricating component 52, and a coil spring 54. A tip end portion 52a of the lubricating component 52 has a perpendicular cross section in the linear motion direction that is a semicircle, the same as the cross section of the spherical surface rollers 3. The lubricating component 52 is pressed against the raceway 11 of the guide rail 1 by the coil spring 54. COPYRIGHT: (C)2007,JPO&INPIT
