Claims

[Scope of utility model registration request]

In a steering column formed by connecting the pipe and the shaft with a resin part that absorbs impact energy interposed between the pipe and the shaft, a serration engagement part that transmits rotational torque is provided on the outer periphery of the shaft and the inner periphery of the pipe. A collapsed structure for a steering column, characterized in that a resin part is formed on the shaft by injection molding so as to prevent rotation thereof, and the resin part is fitted into a serration part of a pipe so as to bite into it.
