PROBLEM TO BE SOLVED: To achieve a structure that can ensure silence during position adjustment of a steering wheel 8 by a feed screw mechanism 16, and that can achieve an improvement in the protection of a driver at the time of a collision accident. SOLUTION: A nut 17 being a driven member is mounted such that it can be detached from an inner column 3a constituting a steering column 1a, based on a shock load applied at the time of a secondary collision. Therefore, at the time of a secondary collision, a threaded rod 18 constituting the feed screw mechanism 16, does not have resistance with respect to displacement of the inner column 3a in the forward direction, and hence an improvement in the protection of the driver can be achieved. Moreover, since an integrated member can be used for the threaded rod 18, silence during the position adjustment can be ensured. COPYRIGHT: (C)2007,JPO&INPIT |
