Title
(EN) Steering column support apparatus
Abstract
(EN)

Provided is a steering column support apparatus that simplifies tuning for stabilizing the forward displacement of the steering wheel during a secondary collision, and suppresses the absolute value and variation of the break away load without strong rubbing between the bracket 11 on the vehicle side and the bracket 33 on the column side. By forming an extending section 57 on the top plate section 55 of the bracket 33 on the column side, and a convex curved surface 58 on the top surface of the front end section of that extending section 57, a rise in contact pressure at the area of contact that occurs when the edge on the front end of the top surface of the top plate section 55 is pressed against the bottom surface of the bracket 11 on the vehicle side by a moment that is applied from the steering column 6c to the bracket 33 on the column side during a secondary collision is suppressed.
