PROBLEM TO BE SOLVED: To eliminate looseness between a lower rail and an upper rail in a slide rail structure at low cost without increasing the number of parts and fitting work man-hours. SOLUTION: In a slide rail for a vehicle seat provided with a lower rail 5 and an upper rail 6, at least three rollers 11, 12 are attached on the upper rail 6 at a designated interval. The first roller 11 and the second roller 12 are arranged with shifts in vertical directions to press contact on an inner surface of a bottom wall 5a of the lower rail 5 and an inner surface of a top wall 5c of the lower rail 5 respectively. Looseness in the vertical direction between the lower rail 5 and the upper rail 6 can be surely prevented without providing any looseness preventing rollers by taking such a structure, and a slide rail structure capable of smoothly operating with very little looseness can be provided at low cost.
