Abstract

A drive shaft, particularly for motor vehicles, has metallic end members having facing axially inner sections of larger diameter, axially outer sections of smaller diameters and transition sections connecting the inner and outer sections. The end members are, with the exception of small axial lengths of the outer sections, embedded in and surrounded by a tubular shaft member which is constructed by winding a plurality of layers of carbon or glass-fiber roving impregnated with synthetic plastic, onto a lost mandrel and heat-hardening the synthetic plastic.
