Abstract

A shaft assembly is assembled by press-fitting a tube of fiber-synthetic material and a rigid connection structure which includes an outer sleeve and an inner connecting member. The outer sleeve has axially extending inward projections which engage the tube at one end of the sleeve and the inner connecting member at the other end of the sleeve. This permits the sleeve and the inward projections therein to be made in a simpler manner.
