摘要

A supporting apparatus for a steering bracket includes, a steering bracket supporting a steering column and including a first capsule-side hole and a second capsule-side hole, a separation capsule including a first bracket-side hole and a second bracket-side hole, a resin member straddling the first bracket-side hole and the first capsule-side hole, a shear pin straddling the second bracket-side hole and the second capsule-side hole, and a cam mechanism including a rotatable weight portion to pull out the shear pin from the second bracket-side hole, the weight portion constituted to rotate around the shear pin by inertia due to a primary collision and to move to a front of a vehicle, and the cam mechanism constituted to pull out the shear pin from the bracket-side hole by a rotation of the weight portion.
