Spring drive mechanism for toy micro-vehicles, of the type consisting of a drum or barrel serving as a coiling base to a spiral spring having its outer end anchored to a fixed point and the internal to said drum, being loaded said spring by rotating a faceted shaft operated by uncoupling key, which is fixedly related to the winding drum and with a pinion, transmitter of the movement of the drum when the spring is discharged, which essentially is characterized in that it is constituted from a single piece that comprises two rotating supports, a pinion, a winding drum and a faceted axis of very little length, all of it located on a common axis so that its rotation is concentric, and because the key of drive of the faceted shaft is constituted by a piece of circular plant of great radius provided by one of its faces with an axially drilled bulge and through it is in correspondence with the faceted axis, whose bulge is flanked by two diametrake drive lugs.
