Zusammenfassung:PROBLEM TO BE SOLVED: To provide a steering engine which can reduce tooth hammer caused when a toothed gear turns in reverse, and can prevent deterioration by dynamic behavior of a steering shaft.SOLUTION: A steering engine comprises a steering shaft, a steering shaft gear fixed to the steering shaft, a motor, and at least one planet gear 20 rotating by driving force of the motor and transmitting torque to the steering shaft gear. The planet gear 20 comprises a first toothed gear 21 fixed to a planet shaft 30 and having a gap between the tooth surface and a tooth surface of the steering shaft gear, and a second toothed gear 22 contacting with the first toothed gear 21, provided being coaxial with the first toothed gear 21, having no gap between the tooth surface and the tooth surface of the steering shaft gear, and rotatable around the planet shaft 30.
