A steering control device is provided that synchronizes the driving operations of swash plate control servomechanisms. In roll control, the control amount adjustment circuit FR separates and converts the roll control signal R into a roll servo drive control amount and a collective pitch servo drive control amount. The offset correction circuit OR offset-corrects the converted control amounts and outputs a servo control signal converted into the roll servo control amount RR and a servo control signal converted into the collective pitch servo control amount RC. The adder receives the roll servo control signal and the collective pitch servo control signal and adds them with a pitch control signal and a collective pitch control signal. Thereafter, the synchronous circuit DR synchronizes the added signals. The roll servo control output SR, the pitch servo output SP, and the collective pitch output SC are respectively output to the servo mechanisms with the same timing.
