STEERING COLUMN APPARATUS

摘要

Construction is achieved in which a held bracket section 30 is integrally formed with the end section of an outer column by a hydroforming method, so as to be able to substantially ensure the strength and rigidity of the held bracket section 30. A spacer 37 that is made of a material that is softer than the metal plate of the outer column 20a is assembled in the inside of the held bracket section 30 and between a pair of left and right held plate sections 31. Holes for inserting a rod for fastening the position of the steering wheel are provided in portions of the spacer 37 and held plate sections 31 that are aligned with each other.

1. A steering column apparatus comprising:
a cylindrical inner column; a cylindrical outer column having an end section that fits with an end section of the inner column; a held bracket section that is integrally formed with the outer column in the end section of the outer column that fits with the end section of the inner column by causing a metal plate of the outer column to swell outward in a radial direction of the outer column; the held bracket section comprising a pair of left and right held plate sections that are parallel with each other, and having a pair of through holes that are formed in portions of the held plate sections that are aligned with each other through which a rod for expanding or contracting a space between the held plate sections is inserted; and a spacer formed of a material that is softer than the metal plate of the outer column, the spacer having insertion holes for inserting the rod in portions that are aligned with the through holes, the spacer assembled on the inside of the held bracket section and between the held plate sections.
