To attach a reinforcement member to an upper rail without backlash by use of an upper rail side wall.SOLUTION: A screw shaft 17 moves back and forth by rotating with respect to a nut member 19, and in association with this movement, an upper rail 3 moves back and forth with respect to a lower rail 1. A pair of left and right slits 3g which extend from lower ends of side walls 3b, 3c to an intermediate position, are formed in a pair of left and right side walls 3b, 3c of the upper rail 3. Both of left and right side edges of reinforcement plates 29, 31 are fitted in the pair of left and right slits 3g. The upper rail 3 has a pair of left and right tongue piece portions 3j which are positioned above the slit 3g and are formed on the side walls 3b, 3c. The reinforcement plate 29, 31 have pair of left and right recesses 29e which are formed in upper portions of both of left and right side edges and with which the pair of left and right tongue piece portions 3j engage. The tongue piece portion 3j enters in the recess 29e in a state in which an upper end surface 3ju abuts on upper tapered surface 29tu of the recess 29e, and is bent into S shape in the recess 29e and engages with the recess 29e.SELECTED DRAWING: Figure 3

    【課題】アッパレールの側壁を利用して補強部材をガタなく取り付ける。【解決手段】スクリュ軸17は、ナット部材19に対して回転することで前後移動し、これに伴いアッパレール3がロアレール1に対して前後移動する。アッパレール3の左右一対の側壁3b,3cに、側壁3b,3cの下端から中間位置まで延びる左右一対のスリット3gが形成される。左右一対のスリット3gに補強プレート29,31の左右両側縁が嵌合する。アッパレール3は、スリット3gよりも上方に位置させて側壁3b,3cに形成される左右一対の舌片部3jを有し、補強プレート29,31は、左右両側縁の上部に形成され、左右一対の舌片部3jが係合する左右一対の凹部29eを有する。舌片部3jは、上端面3juが凹部29eの上側テーパ面29tuに当接した状態で凹部29e内に入り込んでいると共に、凹部29e内においてS字形状に屈曲されて凹部29eに係合している。【選択図】図3
