PROBLEM TO BE SOLVED: To provide a power steering device that enables reduction in friction between a motor housing and a gear housing.SOLUTION: A relative rotation support mechanism 50 used for supporting relative rotation between a gear housing 10 comprising first and second gear housings 11, 12 and a motor housing 30 in means 40 for adjustment between axes comprises: a projecting insertion part 51 installed on the motor housing 30 side; a reception part 52 that is installed on the second gear housing 12 side and to which the insertion part 51 can be fitted; and an annular seal member 53 that is interposed between the insertion part 51 and the reception part 52 and comprises a resin material such as rubber. A covering part covered with a material having a smaller friction coefficient than that of any of the resin, the gear housing 10 and the motor housing 30 is installed on the outer surface of the seal member 53. |
