In a steering apparatus for a car which presses and retains a steering column upon a fixing bracket to car body to be telescopically adjustable, the steering column is molded from a tubular material by a hydroforming process to have a swelled portion as a unitary structure thereof. There is formed on each side surface of this swelled portion an elongated hole for telescopic adjustment through which a fastening bolt of a clamp mechanism provided on a fixed bracket to steering column is inserted.
