To provide a seat rail device which can easily achieve weight saving of a reinforcement configuration which suppresses deformation of a lower rail.SOLUTION: A lower rail 20 is so formed as to guide plural rollers 51 which are supported by one side support part 31a and the other side support part 32a of an upper rail 30 respectively at one side guide part 22a and the other side guide part 22b which are opposite to each other via a bottom wall 21 and are so connected to the bottom wall 21 as to extend in a slide direction. Further, one side guide part 22a and the other side guide part 22b are respectively provided with an inner wall part 26 which are hung down from an inner end of a top face 23 with which the roller 51 is brought into rolling contact. A spacer 40, which is assembled to the upper rail 30 and has one side piece part 41 which is interposed between one side surface and the inner wall part 26 and has a gap G1 provided between itself and the inner wall part 26, and the other side piece part 42 which is interposed between the other side surface and the inner wall part 26 and has a gap G2 provided between itself and the inner wall part 26, is provided.SELECTED DRAWING: Figure 2

    【課題】ロアレールの変形を抑制する補強構成の軽量化を容易に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案内部22a及び他側案内部22bにて、アッパーレール30の一側支持部31aと他側支持部32aとにそれぞれ支持される複数のローラー51を案内するように形成される。また、一側案内部22a及び他側案内部22bには、ローラー51が転がり接触する上面23の内側端から垂下する内壁部26がそれぞれ設けられる。そして、アッパーレール30に組み付けられて、一側面と内壁部26との間に介在し当該内壁部26との間に隙間G1が設けられる一側片部41と、他側面と内壁部26との間に介在し当該内壁部26との間に隙間G2が設けられる他側片部42と、を有するスペーサー40が設けられる。【選択図】図2
