Abstract
In the case where an intake valve has its phase in a first region between a most retarded angle and CA(), the rotational speed of relative rotation between an output shaft of an electric motor and a sprocket is reduced at a reduction gear ratio R() to change the phase of the intake valve. In the case where the intake valve has its phase in a second region between CA() and a most advanced angle, the rotational speed of relative rotation is reduced at a reduction gear ratio R() to change the phase of the intake valve. As long as the rotational direction of relative rotation is the same, the phase of the intake valve is changed in the same direction for both of the first region between the most retarded angle and CA() and the second region between CA() and the most advanced angle.
