<P>PROBLEM TO BE SOLVED: To provide a steering apparatus in which a rolling bearing rotatably journaling a steering shaft is provided, an upper column and lower column are fitted slidably in an axial direction, and which has enhanced driving stability of a steering wheel during high speed running. <P>SOLUTION: An outer circumferential surface 312 of a female steering shaft 31 is fastened by a cylindrical surface 661 of a bush 6 by elastic force of an O-ring 64. Thereby a prescribed frictional force is generated between the outer circumferential surface 312 of the female steering shaft 31 and the cylindrical surface 661 of the bush 6 and thereby driving stability of the steering wheel during high speed running is enhanced. Since the O-ring 64 is pushed by an inner circumferential surface 211 of a first lower column 21 in a crushed state, vibration of the female steering shaft 31 is absorbed by the O-ring 64 and transmission of vibration of an axle to the steering wheel can be prevented. <P>COPYRIGHT: (C)2013,JPO&INPIT |
