PROBLEM TO BE SOLVED: To provide a pinion assist type electric power steering device capable of replacing parts even during an assembling process, with high waterproofness and without requiring a strict gap control between a gear housing and a rack housing. SOLUTION: A bearing supporting member 20 fixed with a bearing 21 for supporting an output shaft 32 in a non-movable state in the axial direction is internally fitted in a gear housing 24 integrally assembled with a torque sensor part 3, input/output shafts 31 and 32, a deceleration part and a motor 23. The bearing supporting member 20 is fixed to be non-movable in the axial direction by fitting a snap ring 29 in an annular groove 24b provided in the gear housing 24. COPYRIGHT: (C)2009,JPO&INPIT
