To provide a speed reducer, a drive unit and a steering assist device capable of outputting stable torque to the outside through an output arm, without increasing the size or weight of the whole device or increasing a manufacturing man-hour.SOLUTION: A speed reducer is equipped with an input rotator, a speed reduction mechanism portion, and a cylindrical case 15. The speed reducer rotates by receiving power from a drive device. The speed reduction mechanism portion reduces the rotations of the input rotator. The cylindrical case 15 covers the outside of the speed reduction mechanism portion and rotates by receiving power whose speed is reduced by the speed reduction mechanism portion. The cylindrical case 15 is integrally formed with an output arm 27 that extends from an outer peripheral surface of the cylindrical case 15 outward in a diametrical direction and transmits operational force to the outside.SELECTED DRAWING: Figure 2

    【課題】装置全体の大型・重量化や製造工数の増大を招くことなく、出力アームを通して外部に安定したトルクを出力することができる減速機、駆動ユニット、及び、操舵補助装置を提供する。【解決手段】減速機は、入力回転体と、減速機構部と、筒状ケース15と、を備えている。減速機は、駆動装置から動力を受けて回転する。減速機構部は、入力回転体の回転を減速する。筒状ケース15は、減速機構部の外側を覆い減速機構部で減速された動力を受けて回転する。筒状ケース15には、当該筒状ケース15の外周面から径方向外側に延びて、外部に操作力を伝達する出力アーム27が一体に形成されている。【選択図】図2
