A steering column support apparatus for an electric power-steering apparatus with a tilt mechanism is achieved that is capable of sufficiently maintaining support rigidity of a tilt pivot shaft 15a to support a pivot bracket 28, and keeping the resistance when performing a tilt operation low with the durability of the side plate sections 32c of a pair of bushings 30c sufficiently maintained The portions of the outer circumferential surface of the tilt pivot shaft 15a and the inner circumferential surface of the through hole 29 that hold the cylindrical sections 31 of the bushings 30c are cylindrical surfaces. Moreover, main contact surface sections 36, which come in contact with the inner side surfaces of support plate sections 23 in the neutral state in which there is no assist reaction force, and sub contact surface sections 37, which do not come in contact with the support plate sections 23 in the neutral state, and come in contact with the inside surfaces of the support plate sections 23 only when there is elastic deformation due to the occurrence of an assist reaction force, are formed on outside surfaces of the side plate sections 32c of the bushings 30c. |
