A steering apparatus for an automobile comprising: a steering column; a steering shaft that is supported on the inside of the steering column such that the steering shaft can rotate freely, with a steering wheel being fastened to and supported by the rear end section of the steering shaft that protrudes toward the rear from the rear end section of the steering column; a bracket (11, 11', 11c, 11d) on the vehicle side that comprises a locking hole that is located in the center section in the width direction of the bracket (11, 11', 11c, 11d) and extends in the axial direction of the steering column, the bracket (11, 11', 11c, 11d) being fastened to and supported by a vehicle body such that the bracket (11, 11', 11c, 11d) does not displace in the forward direction during a secondary collision; a bracket (12b, 12d, 12e) on the column side that is supported by the steering column and that displaces in the forward direction together with the steering column during a secondary collision; and a locking capsule (57, 57', 57a) that is fastened to the bracket (12b, 12d, 12e) on the column side, and together with both end sections being locked in the locking hole, both sides on the top end are located on the top side of the bracket (11, 11', 11c, 11d) on the vehicle side in the portions on both sides of the locking hole, by positioning part of the locking capsule (57, 57', 57a) positioned on the inside of locking hole, and connecting this locking capsule (57, 57', 57a) and the bracket (11, 11', 11c, 11d) on the vehicle side, the bracket (12b, 12d, 12e) on the column side being supported by the bracket (11, 11', 11c, 11d) on the vehicle side such that the bracket (12b, 12d, 12e) on the column side can break away in the forward direction by an impact load that is applied during a secondary collision, characterized in that a pair of left and right protruding sections (663, 63a, 63b) is provided in part of the bracket (12b, 12d, 12e) on the column side that protrude further outward in the width direction than the surfaces on the left and right sides of the bracket (12b, 12d, 12e) on the column side, where part of the top edges of these protruding sections (63, 63a, 63b) are caused to closely face through a small space part of the bottom surface of the bracket (11, 11', 11d) on the vehicle side; or a pair of left and right protruding support sections is provided between the portions on both the left and right sides of the bracket on the column side and both the left and right sides of the bracket on the vehicle side in a state where these protruding support sections protrude from one of the brackets toward the other bracket, with the tip end sections of these protruding support sections coming in contact with the other bracket with a contact pressure that allows sliding in the forward direction due to an impact load of the secondary collision. a steering column; a steering shaft that is supported on the inside of the steering column such that the steering shaft can rotate freely, with a steering wheel being fastened to and supported by the rear end section of the steering shaft that protrudes toward the rear from the rear end section of the steering column;
