PROBLEM TO BE SOLVED: To provide a suspension cross member structure, a simple structure utilizing a steering gear box, which is configured to allow a site having a recessed part for interference avoidance to be reinforced sufficiently.SOLUTION: The suspension cross member structure comprises: a cross member 1 which joins an upper panel 3 to a lower panel 5, has extension parts 2a protruding outside and has a recessed part 7 at a lower surface part thereof; a steering gear box 21 arranged between the extension parts so that a housing part 27 strides across the recessed part; an end-side fixing part 31 that fixes both sides striding across the recessed part, of the housing part 27 to the extension parts; and a center-side fixing part 33 that fixes the center of the housing part to a space between the extension parts. The cross member has a swelling-out part 8a adjacent to the housing part. The center-side fixing part has: an opening part 47 formed at a wall part facing the housing part, of the swelling-out part; an inserted part 41 which is inserted from the housing part into the opening part to fill a space between an upper panel and a lower panel of the swelling-out part; and connecting parts 44 and 51 which fasten the upper panel and the lower panel of the swelling-out part to each other.SELECTED DRAWING: Figure 4
