Abstract
A fastening device for a tiltable steering shaft assembly of the type in which, when shifted into a remote position upwardly from a pre-selected angular position, the steering wheel is automatically returned to the pre-selected angular position and locked at the same position only by depression of the steering wheel. The fastening device comprises a first manual lever arranged to release the fastening device for permitting upward movement of the steering wheel to the remote position, and a second manual lever arranged to readjust the pre-selected angular position of the steering wheel in accordance with a user's physique, in which the first manual lever is cooperable with the second manual lever in operation of the latter to carry out readjustment of the pre-selected angular position of the steering wheel in a simple manner. The fastening device further includes a mechanism for avoiding unexpected trouble caused by an error in operation of the second manual lever.
