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

    【課題】大きな負荷が生ずる環境下においても、適切に動作することができる操舵補助装置を提供することを目的とする。【解決手段】本出願は、ステアリングシャフトに加わる操舵力に応じた駆動力を出力するモータと、前記駆動力に応じて揺動回転運動する歯車部と、前記歯車部と噛み合う内歯環が形成された外筒と、前記揺動回転運動に応じて回転し、操舵補助力を、ステアリングホイールに与えられた回転操作に応じて車輪の向きを変える操舵機構に出力するキャリアと、を含む減速機と、を備える操舵補助装置を開示する。前記歯車部と、前記内歯環と、の間の噛合率は、25%以上100%以下である。【選択図】図1
