In a steering apparatus configured by including: a steering shaft to which a steering wheel can be fitted; a steering column 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, the improvement comprises: a spacer having an inner peripheral surface that is fixedly fitted onto an outer peripheral surface of an end portion of the steering column on a rear side with respect to a vehicle body 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; and a rotation preventive mechanism preventing the spacer from rotating about the steering column. With this configuration, the same combination switch can be fitted to plural types of columns having different dimensions of outer diameters.
