Abstract
A large drive shaft is formed of an extruded metal, thin wall tube, having integral, annular, inwardly thickened, ring-like areas at its opposite ends. A number of radially inwardly directed ribs are integrally formed upon the inner wall surface of the tube wall and extend the full length of the tube between the ring-like areas. The ribs are spaced apart from each other and, preferably, area of a height which is less than the thickness of the thin wall. The opposite ends of the shaft are provided with conventional connecting means for connecting the shaft to a drive device and a driven device transmitting power therebetween.
