  • Steering apparatus
    Patent number: 7765888
    Abstract: A steering apparatus comprises a bearing for supporting a pinion shaft so as to be rotatable and a high-rigidity member for holding the bearing in a state where it is positioned with respect to a housing. The housing comprises cylindrical first and second housings whose respective ends are fitted to each other. The first and second housings respectively comprise first and second receiving sections directly or indirectly receiving an outer ring of the bearing in an axial direction. The outer ring of the bearing is held between the high-rigidity member and the second receiving section, so that the axial movement of the bearing relative to the first and second housings is regulated.
