PROBLEM TO BE SOLVED: To provide a steering auxiliary device which can suitably operate even in an environment in which a large load is generated.SOLUTION: There is disclosed a steering auxiliary device which comprises a reduction gear including: a motor for outputting a drive force corresponding to a steering force applied to a steering shaft; a gear part which rotationally operates so as to be oscillatory according to the drive force; an outer cylinder in which an inner tooth ring engaged with the gear part is formed; and a carrier which rotates according to the oscillatory rotation operation, and outputs a steering auxiliary force to a steering mechanism which changes an orientation of wheels according to the rotation operation which is imparted to a steering wheel. A gearing rate between the gear part and the inner tooth ring is not lower than 25% and not higher than 100%.SELECTED DRAWING: Figure 1
