摘要： A collapsible steering column apparatus comprises a steering shaft in which a steering wheel is fixed to one end and a whole length in the axial direction can be contracted and a steering column in which a whole length in the axial direction can be contracted by inserting the edge portion of an inner column to the inside of the edge portion of an outer column. A first engaging portion is formed near the edge portion of the outer column. The first engaging portion comprises a pair of first arc portions which face each other and are respectively come into contact with the outer peripheral surface of the edge portion of the inner column and a pair of second arc portions which are arranged between the pair of first arc portions and are away from the outer peripheral surface of the edge portion of the inner column by having a radius of curvature which is smaller than a radius of curvature of the outer peripheral surface of the edge portion of the inner column. A second engaging portion is formed in the portion which is slightly near the center of the outer column than the first engaging portion. The second engaging portion comprises a pair of third arc portions which face each other and are respectively come into contact with the outer peripheral surface of the edge portion of the inner column and a pair of fourth arc portions which are arranged between the pair of third arc portions and are away from the outer peripheral surface of the edge portion of the inner column by having a radius of curvature which is smaller than the radius of curvature of the outer peripheral surface of the edge portion of the inner column. A length of the pair of third arc portions is set to be longer than a length of the pair of first arc portions.

摘要： Provided is steering column support construction that together with eliminating strong rubbing between the bottom surface of a vehicle-side bracket 23a and the top surface of a column-side bracket 22a, and keeping the absolute value and fluctuation in the break away load small, more completely protects the driver during a collision accident without lowering the freedom of design of the steering apparatus. An adjustment rod 27 for adjusting the position of a steering wheel is provided on the top side of a steering column 6b. During a secondary collision, a moment that is applied to the column-side bracket 22a is kept small, friction at the area of rubbing between the column-side bracket 22a and the vehicle-side bracket 23a is reduced, and the break away load is kept low. Moreover, the driver's knees are protected by eliminating the portion that protrudes further downward than the steering column 6b.

摘要： The present invention provides construction that keeps the load required for a locking capsule 50d that is supported by the steering column to come out in the forward direction from a locking hole 48b that is formed in a fastening bracket 11e on the vehicle side low. Small through holes 52e are formed in a flange section 51d of the locking capsule 50d. Small notch sections 62a that are each open toward the inside of the locking hole 48b are formed in portions of the fastening bracket 11e on the vehicle side around the locking hole 48b that are aligned with each of the small through holes 52e. Injection molding is performed to inject synthetic resin 72 such that the synthetic resin 72 spans between these small through holes 48b and small notch sections 62a, and connects the locking capsule 50d and the fastening bracket 11e on the vehicle side. Moreover, part of the synthetic resin 72 penetrates into and solidifies in a small space 71 between the inside surfaces of the locking hole 48b and the outside surfaces of the locking capsule 50d.
