  • Patent number: 8955883
    Abstract: When the guide bracket 61 is fixed to the vehicle-mounting bracket 21 by the guide pin 71, the upper surfaces 24c, 24c of the capsules 24, 24 are in contact with the lower surfaces 61c, 61c of the flange portions 61b, 61b on the guide bracket 61, and the first engaging portions 64, 64 and the second engaging portions 65, 65 engage with the capsules 24, 24. As a result, even before fixing the vehicle-mounting bracket 21 and the guide bracket 61 to the vehicle body 41 by the bolt 22, the guide bracket 61 does not rotate with respect to the vehicle-mounting bracket 21 about the guide pin 71, or move in the forward and rearward direction, or in the vehicle body width direction.

  • Patent number: 8904901
    Abstract: A steering device is provided that facilitates an operation of mounting a friction plate on a mounting bracket. A first friction plate and a second friction plate just need to be mounted on an outer column only. It is possible to greatly facilitate an operation of assembling alternate layers of the first friction plate and the second friction plate at specified orientations. When the outer column is displaced telescopically, a tightening rod touches a long slit in the second friction plate. The second friction plate rocks around a columnar protrusion as the rocking center. The long slit is formed lengthwise in a direction of tilt positioning. The long slit absorbs a difference between a rocking trajectory formed by the second friction plate and a linear trajectory formed by the outer column. The second friction plate smoothly rocks. The outer column can be smoothly adjusted in the telescopic direction.
