STEERING APPARATUS
First Claim
1. In a steering apparatus comprising:
- a steering shaft capable of attaching a steering wheel at rearward end thereof with respect to a vehicle body;
a steering column that rotatably holds the steering shaft inside thereof and moves frontward with respect to the vehicle body upon a secondary collision;
a vehicle-mounting bracket that holds the steering column and moves frontward with respect to the vehicle body together with the steering column while collapsing upon the secondary collision;
a couple of capsules that are disposed in a width direction with respect to the vehicle body, fixed to the vehicle body, and on which the vehicle-mounting bracket is attached so as to hold the vehicle-mounting bracket to the vehicle body, and make the vehicle-mounting bracket detach from the vehicle body while absorbing predetermined impact energy upon the secondary collision;
a fixed bracket that is attached to the vehicle-mounting bracket to be fixed to the vehicle body and remained to the vehicle body upon the secondary collision; and
a guide mechanism that guides the movement of the vehicle-mounting bracket upon the secondary collision;
the improvement comprises;

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.
