PROBLEM TO BE SOLVED: To suppress a manufacturing cost by changing driving circuits of two reaction force motors to one driving circuit and enable a control method by switching a rotation direction in a steering reaction force control device for controlling reaction force by the two reaction force motors.SOLUTION: A steering reaction force control device in a vehicular steering device 1 includes a reaction force application section 3 which applies steering reaction force to a steering wheel 2 by two reaction force motors (1) and (2) 8a and 8b. A motor driving circuit 21 which drives the two reaction force motors (1) and (2) 8a and 8b is an H-bridge circuit 26. The motor driving circuit includes opening/closing switches SW3 and SW4 which open/close each energization circuit 23 and 24 of the two reaction force motors (1) and (2) 8a and 8b; and changeover switches SW1 and SW2 which can switch an energization direction of the energization circuit 23 or 24 in one of the two reaction force motors (1) and (2) 8a and 8b.SELECTED DRAWING: Figure 4
