PROBLEM TO BE SOLVED: To provide an electrically driven power steering, which is reduced in weight and improved in a detection accuracy of a torque sensor.SOLUTION: An electrically driven power steering device 100 includes an intermediate shaft 14 for transmitting a steering torque to an input shaft 15. The input shaft 15 and the intermediate shaft 14 are connected in a state that the mutual rotation axes are crossing each other via a universal joint 80a. A housing 50 is formed with a rib 56 and a window 53 in which rigidity of the housing 50 in a first direction D1 orthogonal to the rotational center axis of the input shaft 15 and the rotation center axis of the intermediate shaft 14 is increased as compared with the rigidity of the housing 50 in a second direction D2 orthogonal to the first direction D1 and the rotation center axis of the input shaft 15.SELECTED DRAWING: Figure 5

    【課題】電動パワーステアリング装置を軽量化しかつトルクセンサの検出精度を向上させる。【解決手段】電動パワーステアリング装置100は、操舵トルクを入力シャフト15に伝達する中間シャフト14と、を備え、入力シャフト15と中間シャフト14とは、ユニバーサルジョイント80bを介して、互いの回転中心軸が交差した状態で連結され、ハウジング50には、入力シャフト15の回転中心軸と中間シャフト14の回転中心軸とに直交する第1方向D1におけるハウジング50の剛性を、第1方向D1と入力シャフト15の回転中心軸とに直交する第2方向D2におけるハウジング50の剛性に比して高めるリブ56及び窓部53が形成される。【選択図】図5
