To reduce the size, in an axial direction, of an input shaft of a drive system.SOLUTION: A steering drive device 50 that drives an input shaft for inputting rotation force, as steering torque, to a steering system that steers a vehicle by applying angle of deviation to the vehicle to be automatically steered, comprises: a transmission shaft 501 having a rotation shaft connectable so as to be integrally rotated with the input shaft, provided with a gear 501a along an outer periphery of the rotation shaft, and configured to transmit drive force to the input shaft; a motor 502 having a rotation shaft 502a provided with a gear 502b engaged with the gear 501a of the transmission shaft 501 and configured to drive the transmission shaft 501 by its being disposed such that an axial direction of the rotation shaft 502a is directed in a direction orthogonal to an axial direction of the transmission shaft 501; and an encoder 503 having a rotation shaft 503a provided with a gear 503b engaged with the gear 501a of the transmission shaft 501 and detecting rotation of the transmission shaft 501 by its being disposed such that an axial direction of the rotation shaft 503b is directed in the direction orthogonal to the axial direction of the transmission shaft 501.SELECTED DRAWING: Figure 7

    【課題】 駆動系の入力軸の軸方向におけるサイズを縮小する。【解決手段】 自動操舵の対象である車両の車輪に偏角を与えて車両を操舵する操舵系に操舵トルクとしての回転力を入力する入力軸を駆動する操舵駆動装置50であって、入力軸と一体回転するように接続可能な回転軸を有し、回転軸の外周に沿って歯車501aが設けられ、入力軸に駆動力を伝達する伝達軸501と、伝達軸501の歯車501aと噛合う歯車502bが設けられた回転軸502aを有し、回転軸502aの軸方向が伝達軸501の軸方向と直交する方向を向くように配置されて伝達軸501を駆動するモータ502と、伝達軸501の歯車501aと噛合う歯車503bが設けられた回転軸503aを有し、回転軸503bの軸方向が伝達軸501の軸方向と直交する方向を向くように配置されて伝達軸501の回転を検出するエンコーダ503とを備える。【選択図】図7
