  • Patent number: 10486731
    Abstract: A stopper bracket (40) is fixed to an inner pipe (13) at a location between the pair of clamp parts (23 and 23). The hanger bracket (50) is assembled with the stopper bracket (40), and a pair of side plates (51 and 51) of the hanger bracket (50) are interposed between the pair of clamp parts (23 and 23) and the pair of outer column support parts (11a and 11a). The guide mechanism (60) guides the hanger bracket (50) so that the hanger bracket (50) is restricted from displacing relative to the stopper bracket (40) in a front-rear direction of a vehicle and is capable of displacing relative to the stopper bracket (40) in a vehicle width direction. A support mechanism (70) supports the hanger bracket (50) relative to the stopper bracket (40).

  • Patent number: 9540034
    Abstract: A steering apparatus includes: an outer column and an inner pipe retained by the outer column for movement in a front-rear direction of a vehicle, an inner-pipe retaining section with opposed leg sections interconnected via a fastening mechanism. The apparatus further includes an impact energy absorbing member provided on the inner pipe and having a generally U sectional shape along the axis line of the inner pipe. The absorbing member includes: a base section mounted to the inner pipe; an abuttable section bent from the rear end of the base section such that it is abuttable against the fastening mechanism; and an energy absorbing section bent forward from one end of the abuttable section such that, when an impact is input to the inner pipe, the absorbing section absorbs energy of the impact while deforming by abutting against the fastening mechanism.

  • Patent number: 8967017
    Abstract: A steering device includes a housing constituted by an enclosing main body section, a separation section formed on two sides of on the lower side of the enclosing main body section along the axial direction thereof, and clamping sections formed respectively on two sides of the enclosing main body section so as to face each other in the lateral direction of the separation section; a fixed bracket having fixed side sections that clamp the housing at two sides in the lateral direction; a clamp that clamps the two clamping sections of the housing and the two fixed side sections of the fixed bracket; an outer pipe having at the axially front side thereof a slit formed in the axial direction; and an inner pipe inserted into the inner circumferential side of the outer pipe.
