<p><P>PROBLEM TO BE SOLVED: To provide a steering device suitable as a steering device which includes a roller bearing for rotatably supporting a steering shaft, and an upper column and a lower column slidably fitted to each other in an axial direction, the steering device being improved in a stability of a steering during high speed traveling. <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 using an elasticity of an O-ring 64. Therefore, a predetermined friction 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 the steering stability of the steering wheel 103 while traveling at high speed improves. Further, since the O-ring 64 is in a crushed state due to being pressed by an inner circumferential surface 211 of a first lower column 21, the vibration of the female steering shaft 31 is absorbed by the O-ring 64, and the vibration of a vehicle shaft is prevented from being transmitted to a steering wheel 103. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
