To provide a seat rail device which can inhibit abnormal noise and rattling.SOLUTION: A front surface 62 and a rear surface 63 of a nut body 60 as seen in a seat anteroposterior direction are formed in curved surface shapes so that an anteroposterior width of the nut body 60 becomes smaller with increasing vertical distance from a screw hole 61, and clearances are formed between the surfaces 62, 63 and an elastic member (a damper) 70 enclosing the nut body 60. Thus, when vibration is applied to the nut body 60, movement in directions other than the seat anteroposterior direction is absorbed with the clearances and the vibration is not easily transmitted to a lower rail 20. Therefore, rattling of a seat rail device can be reduced.SELECTED DRAWING: Figure 3

    【課題】異音・ガタつきを抑制できるシートレール装置を提供することを目的とする。【解決手段】ナット体60のシート前後方向の前面62および後面63が曲面状に形成され、ネジ孔61から上下方向に離れるにつれて前後幅が小さくなるように形成され、ナット体60を囲う弾性部材(ダンパー)70との間に隙間が生じているため、ナット体60に振動が加わった際にシート前後方向以外の動作がその隙間で吸収されてロアレール20に伝わりにくくなるため、シートレール装置のガタつきを低減することができる。【選択図】図3
