ABSTRACT:
The crankshaft is of the type comprising, in succession in its longitudinal direction, a crank pin intended to receive a connecting rod big end, an eccentric of flattened sector shape, and an elongate tubular part, non-coaxial with respect to the crank pin and acting partly as a journal and partly as a support for a rotary member, such as a rotor of an electric motor. The crank pin and the eccentric are made in a single metal piece and the elongate tubular part is constituted by a separate tubular metal piece. The face of the eccentric which is turned towards the tubular piece and the corresponding end of this piece have respective annular formations engaged and retained one in the other by means of welding or glueing.
