摘要： Under a state of a normal temperature, a pitch B2 of a feed nut 55, 65 is formed to be slightly larger than a pitch A2 of a feed shaft screw 53, 63. Accordingly, since the screw thread of the feed nut 55, 65 is pressed to the screw thread of the feed screw shaft 53, 63 with a small interference, there is no backlash between the feed screw shaft 53, 63 and the feed nut 55, 65 so that a smooth feeding operation can be carried out. Under a state of a low temperature, the feed nut 55, 65 contracts more than the feed screw shaft 53, 63. As a result, a pitch B1 of the feed nut 55, 65 has the substantially same dimension as that of a pitch A1 of the feed screw shaft 53, 63.

摘要： In a motor-driven steering wheel position adjustment apparatus, a nut 17 being a driven member is mounted such that it can be detached from an inner column of a steering column, based on a shock load applied at the time of a secondary collision, and therefore a threaded rod of a feed screw mechanism does not have resistance with respect to displacement of the inner column in the forward direction at that time. Improvement in the protection of a driver at the time of a collision can thus be achieved, and, since an integrated member can be used for the threaded rod, silence during the position adjustment of a steering wheel by the feed screw mechanism can be ensured.
