To provide an electrically-driven seat slide device which improves and stabilizes support strength even in a structure in which a front end of a screw shaft is fixed and supported on a lower rail by a single bracket.SOLUTION: An electrically-driven seat slide device includes: a lower rail 2; a slide type upper rail; a screw shaft 4; and a gear box having a gear engaged with the screw shaft 4. A front side bracket 9 which fixes a front end of the screw shaft 4 to the lower rail 2 has a bottom wall section 19, a vertical wall section 20, and a pair of right and left leg side sections 21 erecting from both side end faces of the vertical wall section 20. Each engagement recess 25 is formed to be engaged with an opening edge of a support hole 26 formed in the lower rail 2 and hold the opening edge 26 from both front and rear faces at lower ends at tips of the pair of leg side sections 21.SELECTED DRAWING: Figure 6
【課題】スクリューシャフトの前端部が単一のブラケットでロアレールに固定支持されている構造であっても、その支持強度の向上と安定化を図った電動式シートスライド装置を提供する。【解決手段】ロアレール2と、スライド式のアッパーレールと、スクリューシャフト4と、スクリューシャフト4に螺合するギヤを有するギヤボックスと、を備える。スクリューシャフト4の前端部をロアレール2に固定している前側ブラケット9は、底壁部19と、縦壁部20と、縦壁部20の両側端面から直立する左右一対の脚辺部21と、を有する。一対の脚辺部21の先端部下端には、ロアレール2に形成された支持孔26の開口縁に係合して、開口縁26を表裏両面から挟み込む係合凹部25が形成されている。【選択図】図6
