Geared motor comprising an inductor associated with an armature consisting of a plating 1 of metal sheets between which are wound electric wires 2 of a shaft 3 passing axially through this plating as well as of a collector 4, an endless screw 5 being formed on the shaft 3 between smooth portions 6, 7 in order to transmit the torque developed during the rotation of the armature, characterised in that the threading of the screw 5 has an outer diameter D greater than that d of its smooth portions 6, 7 and in that the collector 4 has a tapping 9 adapted to cooperate with the threading of the screw 5 so as to allow the collector 4 to pass across the screw and to fit onto a smooth portion 7 of the shaft 3 beyond the screw 5. The invention enables the screw 1 to transmit significant torques in a simple and very inexpensive way as compared with the known systems, for example those having a screw rolled on an extension of the shaft or having a screw driven onto the shaft with emergent bore. <IMAGE>
