A steering apparatus including: a steering shaft to which a steering wheel can be fitted; a steering column to be supported on a vehicle body and supporting the steering shaft rotatably; and a combination switch fixedly fitted to the steering column and constructed by combining a plurality of switches having different functions into one integral unit; characterized by: a diameter-reduced portion formed on a rear side portion, with respect to the vehicle body, of the steering column, the diameter-reduced portion being reduced in diameter relative to a front side portion, with respect to the vehicle body, of the steering column; a bearing fitted in an inner peripheral surface of the diameter-reduced portion and rotatably supporting the steering shaft; a pair of holes formed on a front side, with respect to the vehicle body, of the steering column, closer to the front side with respect to the vehicle body than the bearing; and a spacer having an inner peripheral surface that is fixedly fitted onto an outer peripheral surface of the diameter-reduced portion and an outer peripheral surface that is formed to have a dimension of an outer diameter enabling an inner peripheral surface of a fitting portion provided in the combination switch to be fitted onto the outer peripheral surface, wherein the spacer is made of a synthetic resin and is provided with a pair of engagement portions each having a projection that engages with a corresponding one of the holes so as to regulate movement of the spacer in an axial direction with respect to the steering column, and an inner peripheral surface of the spacer is formed with a plurality of ridges projecting inward in a radial direction at regular intervals in a circumferential direction over an entire length of the inner peripheral surface in an axial direction, thereby the spacer being interference fitted to the outer peripheral surface of the diameter-reduced portion. a diameter-reduced portion formed on a rear side portion, with respect to the vehicle body, of the steering column, the diameter-reduced portion being reduced in diameter relative to a front side portion, with respect to the vehicle body, of the steering column; a bearing fitted in an inner peripheral surface of the diameter-reduced portion and rotatably supporting the steering shaft; a pair of holes formed on a front side, with respect to the vehicle body, of the steering column, closer to the front side with respect to the vehicle body than the bearing; and a spacer having an inner peripheral surface that is fixedly fitted onto an outer peripheral surface of the diameter-reduced portion and an outer peripheral surface that is formed to have a dimension of an outer diameter enabling an inner peripheral surface of a fitting portion provided in the combination switch to be fitted onto the outer peripheral surface, wherein the spacer is made of a synthetic resin and is provided with a pair of engagement portions each having a projection that engages with a corresponding one of the holes so as to regulate movement of the spacer in an axial direction with respect to the steering column, and an inner peripheral surface of the spacer is formed with a plurality of ridges projecting inward in a radial direction at regular intervals in a circumferential direction over an entire length of the inner peripheral surface in an axial direction, thereby the spacer being interference fitted to the outer peripheral surface of the diameter-reduced portion.
