This invention refers to perfected roller-skating doll of the type that alternately moves its legs and head in time, and which has two speeds that alternate while the doll is in operation. The system is based on a gear mechanism worked by a motor, the said mechanism including features that allow the axial movement of a cog wheel so that the latter can engage alternately with one or another pinion, of different sizes, in order to achieve the two speeds. The mechanism is complemented with a drum which is made to revolve in order to transmit movement to the legs. The drum in question is provided with a winding, ring-shaped groove inside which a pin emerging from the respective leg freely moves. This pin is the means whereby the leg is joined to the mechanism assembly and, in particular, to the drum groove. On the shaft on which the drum-affecting pinion is mounted, there is a socket integral with the said pinion and which houses a widened section of the aforementioned shaft. On this widened section is situated a torus with respect to which the shaft can freely slide, in such a way that the revolution of the latter is not transmitted to the drum, thereby constituting a clutch assembly that comes into operation at certain times when it is desired that the motor should work at an idling speed.
