<P>PROBLEM TO BE SOLVED: To provide rolling guide device that can suppress relative displacement with respect to axial directions of rollers, which occurs between the adjacent rollers, and a holding piece arranged at the rolling guide device. <P>SOLUTION: The rolling guide device comprises a plurality of the rollers 6 which are rollingly arranged in a roller roll-traveling passage which is formed between a rail-side roller roll-traveling face formed at a guide rail and a slider-side roller roll-traveling face formed at a slider, and the holding piece 8 interposed between the adjacent rollers 6. Roller grooves 6a extending to circumferential directions of the roller 6 are formed at outer diameter surfaces of the rollers 6, the holding piece 8 bas a body 40 interposed between the adjacent rollers 6, the body 40 has a pair of roller contact surfaces 42a, 42b which oppose the outer diameter surfaces of the adjacent rollers 6, respectively, and protrusions 44 protruding toward the outer diameter surfaces of the rollers 6 and located in the roller grooves 6a are formed at the roller contact surfaces 42. <P>COPYRIGHT: (C)2012,JPO&INPIT |
