A vehicle steering device includes a steering reaction force generating device having a steering reaction force motor; a steering device having a steering motor; a clutch device having an electromagnetic solenoid that sets the steering reaction force generating device and the steering device in a mechanically engaged or disengaged state; a current integrated value acquisition unit that obtains an integrated value of a current of one of the steering reaction force and steering motors; an overload state determination unit that determines whether or not the one motor is in an overload state based on the integrated value of the current supplied to the one motor, obtained by the current integrated value acquisition unit; and a drive control unit that controls driving of the electromagnetic solenoid to set the clutch device in an engaged state when the overload state determination unit determines that the one motor is in an overload state.
