摘要： A steering apparatus has a column 46, a column 42 fitted to the column 46 and able to make collapsing movement or move, a bracket 21 attached to a vehicle body in such a way that it can be detached with the column 42 by an impact force of a secondary collision, a guide bracket 61 fixed to the column 46 and having a guide groove 63, and a pin 71 fixed to the bracket 21 and movable with the bracket 21 while being guided by the guide groove 63. The guide bracket 61 has a flat plate portion 61d that is not contact with the bracket 21. A guide groove 63 is provided in the flat plate portion 61d. The pin 71 has a head portion 713 at the top having a diameter larger than its shaft portion. The apparatus has a gap setting portion that is in abutment with the upper surface of the bracket 21 when the pin 71 is fixed to the bracket 21 to set the distance between the lower surface of the head portion 713 and the upper surface of the bracket 21 to a predetermined value. Thus, there is provided a steering apparatus in which the detaching force upon detachment of the column 42 in the forward direction with respect to the vehicle body by the impact force of a secondary collision can be adjusted accurately with an easy detaching force adjusting operation.

摘要： 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.

摘要： In a steering device having a steering lock device, stress applied to a base portion of a flange section is reduced.
The relief portions (47) and (48) have round corners (471) and (481) formed where the relief portions (47) and (48) meet the outer periphery of the outer column (4), respectively. With the relief portions (47) and (48) concave by β3 from the mounting surface (445), radius R1 of each of the round corners (471) and (481) of the relief portions (47) and (48) can be made larger than radius R2 of a round corner (447) of the mounting surface (445). This makes it possible to avoid interference between the relief portions (47) and (48) and the corner (631) at an inner end, in the vehicle width direction, of the right clamping surface (63) of the steering lock device (6).
