To provide a seat rail device which can reduce a size and weight of a lower rail by reducing respective lengths in a horizontal direction of a pair of right and left lower rails.SOLUTION: A lower rail 20 includes a bottom wall 21, one side wall part 22 and the other side wall part 23 which face each other through the bottom wall 21 and are connected so as to extend to the bottom wall 21 in a slide direction, and an extension part 24 which extends parallel to an opposite part 21a of the bottom wall 21 in a slide direction from an upper end of the one side wall part 22. A roller 41 supported by an upper rail 30 is arranged so as to roll in a vertical direction with respect to the extension part 24 and the opposite part 21a. Side rollers 42, 43 are arranged so as to roll in a horizontal direction with respect to the one side wall part 22 and the other side wall part 23.SELECTED DRAWING: Figure 7

    【課題】左右一対のロアレールにおいてそれぞれの左右方向の長さを小さくすることでロアレールの小型軽量化を図り得るシートレール装置を提供する。【解決手段】ロアレール20は、底壁21と、この底壁21を介して対向し当該底壁21に対してスライド方向に伸びるように連結する一側壁部22及び他側壁部23と、一側壁部22の上端から底壁21の対向部21aと平行であってスライド方向に伸びるように延出する延出部24と備えている。そして、アッパーレール30に支持されるローラー41は、延出部24及び対向部21aに対して上下方向にて転動するように配置され、サイドローラー42,43は、一側壁部22及び他側壁部23に対して左右方向にて転動するように配置される。【選択図】図7
