A steering apparatus for an automobile comprising: a steering column for rotatbly supporting a steering shaft which passes through the inside of the steering column; housing for housing components of an electric power steering apparatus, the housing supported by the vehicle body; a vehicle-side bracket supported by the vehicle body and having a pair of holding plate sections (20a, 20b) that are located at positions on both the left and right sides of the middle section of the steering column, with the portion between the bottom end edges of the vehicle-side bracket being open, the holding plate sections (20a, 20b) having through holes (22a, 22b) that are formed in positions that are aligned with each other; and an expansion and contraction mechanism having a rod shaped member that is inserted in the left right direction through the through holes (22a, 22b) of the holding plate sections (20a, 20b), and a pair of pressing sections (25a, 50) that are provided on both end sections of the rod shaped member, such that by moving the pressing sections (25a, 50) away from each other or close to each other in the axial direction of the rod shape member, the distance between the holding plate sections (20a, 20b) can be changed, and when the distance is contracted, the expansion and contraction mechanism fastens the steering column to the holding plate sections (20a, 20b), characterized in that the steering column comprises a front-end section formed in a U-shape and having a pair of left and right side plate section that face each other, a bottom plate section that connects to the bottom end edges of the side plate sections, and an opening on the top end of the front-end section, the housing comprises a connection and fastening section in the rear-end section, the middle section of the steering column is inserted between the pair of holding plate sections (20a, 20b) from the bottom end edges side of the holding plate sections (20a, 20b). the connection and fastening section is inserted inside the front-end section of the steering column throught the opening on the top end of the front-end section in the direction of from the bottom surface toward the top surface of the steering column and fitted into the front-end section of the steering column with a non-circular fit, the connection and fastening section and the front-end section of the steering column are connected and fastened together by a bolt, and the steering column is assembled in the vehicle-side support bracket and the housing in the direction of from the bottom surface toward the top surface of the steering column. a steering column for rotatbly supporting a steering shaft which passes through the inside of the steering column;
