The electric steering wheel position adjustment apparatus of the present invention is constructed so as to improve the support rigidity of a portion that constitutes a steering column apparatus thereof, such that the steering shaft 2b and the steering column 5b have non-expandable construction, but are able to be displaced in the axial direction; holding holes are provided in at least two locations on the top side of the column holder 31 that supports the steering column 5b; and in each of the holding holes, a sliding plate 35, an elastic member 37 and a cover 38 are assembled such that the sliding plate 35 is elastically compressed by the elastic member 37 and pushes the outer circumferential surface of the steering column 5b.
