PROBLEM TO BE SOLVED: To obtain a structure by which a steering column 4b and a support bracket 17b can be smoothly displaced frontward at a secondary collision.SOLUTION: Both spring-side lock parts 40 of an energization spring 32a are engaged with both lock pieces 41 of a support bracket 17b in a state where both of the lock pieces 41 are pressed downwardly. A pressing part 35a of the energization spring 32a is engaged with a receiving face of a steering column 4b in a state where a pressing force is made to act on an upper part of the steering column 4b. Then, in the case where the energization spring 32a which is displaced frontward together with both of the members 4b, 17b interferes with a gear housing 12 of a steering force auxiliary device 5 in the middle of a stroke at which both of the members 4b, 17b can be displaced frontward at a second collision, the engagement of both of the spring-side lock parts 40 and both of the lock pieces 41 is released, and both of the members 4b, 17b are permitted to be displaced further frontward. |
