PROBLEM TO BE SOLVED: To provide an actuator for a steering device which enables improvement of flexibility of design change regardless of change of the configuration of the liquid pressure power steering side.SOLUTION: An actuator for a steering device includes: a transmission mechanism which transmits rotation of a steering shaft to turning wheels; a piston provided at the transmission mechanism; and a pair of pressure chambers which generates force for moving the piston. The actuator is provided between a liquid pressure power steering device which applies steering force to the turning wheels as the piston moves and a steering wheel and has: a torsion bar connecting an input shaft with an output shaft; a motor rotor which is provided at an outer periphery of the output shaft in a housing and rotates integrally with the output shaft; a motor stator provided at an outer periphery of the motor rotor in the housing; and a rotation angle detection part which is provided in the housing and detects rotation angles of the input shaft and the output shaft or a relative angle between the input shaft and the output shaft.SELECTED DRAWING: Figure 1

    【課題】液圧パワーステアリング側の構成の変更に関わらず、設計変更の自由度を高くすることができるステアリング装置用アクチュエータを提供すること。【解決手段】操舵軸の回転を転舵輪に伝達する伝達機構と、伝達機構に設けられたピストンと、ピストンを移動させる力を発生する1対の圧力室と、を備え、ピストンの移動に伴い転舵輪に操舵力を付与する液圧パワーステアリング装置とステアリングホイールとの間に設けられるステアリング装置用アクチュエータであって、入力軸と出力軸とを接続するトーションバーと、ハウジング内であって出力軸の外周に設けられ、出力軸と一体に回転するモータロータと、ハウジング内であってモータロータの外周に設けられたモータステータと、ハウジング内に設けられ入力軸および出力軸の回転角、または入力軸と出力軸の相対角を検出する回転角検出部と、を有する。【選択図】図1
