Abstract:
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 comprising: a movement-preventing mechanism that is provided for preventing movement of the fixed bracket attached to the vehicle-mounting bracket, with respect to the vehicle-mounting bracket before fixing the fixed bracket to the vehicle body, wherein the movement-preventing mechanism includes at least one of the couple of capsules, and an engaging portion that is formed on the fixed bracket and engaged with said at least one of the couple of capsules, and wherein said engaging portion includes: a couple of first engaging portions each of which protrudes downward from in the vicinity of each of end in the width direction with respect to the vehicle body of the rearward end surface of the fixed bracket, and engaged with the rear end surface of the corresponding capsule; and a couple of second engaging portions each of which protrudes downward from rearward end of each end surface in the width direction of the fixed bracket, and includes a side-surface-width engaging portion engaging with a vehicle-body-width-direction-side of the corresponding capsule and a front-end-surface-engaging portion engaging with a front-end-surface of the same capsule.
