To provide an electrically driven seat slide device which achieves cost reduction while securing rigidity of a support bracket supporting a screw shaft.SOLUTION: A rear bracket 27 includes: a first support member 41 fixed to a lower rail 2; a second support member 42 fixed to the lower rail 2 with the first support member 41; a female screw member 43 serving as a first nut member through which a screw shaft 4 penetrates; and a second nut member 44 through which the screw shaft 4 penetrates. A pair of side wall parts 47 extending along a lower rail longitudinal direction and a vertical wall part 62 of the second support member 42, which is orthogonal to a straight line along the lower rail longitudinal direction, are sandwiched between the female screw member 43 and the second nut member 44.SELECTED DRAWING: Figure 4
