摘要： A steering control device for imparting a steering reactive force to the steering wheel. The steering control device for fork lifts determines a command steering reactive force corresponding to the wheel angle from the wheel angle detected by a wheel angle sensor (41) and table data (60) representing the correlation between the wheel angle and the command steering reactive force and controls an electric brake (31) so that the steering reactive force is equal to the command steering reactive force. A correction coefficient (α1) corresponding to a vehicle state quantity and so forth are determined from the vehicle state quantity (e.g., the wheel angle difference (Δθ)) other than the wheel angle detected by a vehicle state quantity detecting means (e.g., a steering wheel angle sensor (23)) and table data (52) representing the correlation between the vehicle state quantity and the correction coefficient. The table data (60) is corrected by using the correction coefficient (the inclination (α) is determined). The command steering reactive force corresponding to the wheel angle is determined from the table data (60) and the wheel angle. The electric brake (31) is controlled so that the steering reactive force is equal to the command steering reactive force.
