PROBLEM TO BE SOLVED: To withstand repeated load peaks without being exposed to danger of early destruction. SOLUTION: This shaft is a monolithic hollow shaft 11 for transmitting torque, which has a central part 12 which has two end parts 13, 14 each of which is formed of shaft teeth for introducing torque, in axial outer ends, and which has a thinner wall thickness than the end parts 13, 14. When torque is introduced through the shaft teeth, the central member of the central part 12 equal to at least 25% of the length of the monolithic hollow shaft 11 is first, uniformly and elastically torsionally deformed.
