There is provided a steering control device for a vehicle of a new structure utilizing a ball screw mechanism for compacting the structure. The steering control device for a vehicle includes a first input shaft 1 connected to a handle, a second input shaft 2 connected to a motor 8 , an output shaft 3 connected to a steering wheel, a first transmission 6 for rotating a nut 5 in accordance with the rotational motion of the first input shaft 1 so as to transmit the rotational motion of the first input shaft 1 to the rotational motion of the output shaft 3 , and a second transmission 7 for moving the nut 5 linearly in the axial direction with respect to the output shaft 3 in accordance with the rotational motion of the second input shaft 2 so as to transmit the rotational motion of the second input shaft 2 to the rotational motion of the output shaft 3 . The center line of the second input shaft and the center line of the output shaft are aligned on substantially the same straight line.
