<p>PURPOSE:To control the vibration of a steering system to the full by varying the length of a steering shaft by means of a telescopic column mechanism, through which if a vibro-frequency in this steering system is varied to some extent, another vibro-frequency in a dynamic damper is automatically regulated. CONSTITUTION:A conical surface 5, whose upper side comes to a small diameter on an upper shaft 2, is formed on a shaft peripheral surface, and a holder 6 attached tight to a steering tube 3 at the outside of this upper shaft 2, supports an elastic body 9, while a sliding part 8 in slidingly contact with the conical surface 5 is attached tight to one end of the elastic body 9, and a mass body 7 is attached tight to the other end, so it is so constituted as placing a deformation effective interval 12 between the holder 6 and the mass body 7.</p> |
