Toy mixer truck, essentially characterized by the fact that, in the tipper tilting box on which the concrete mixer is mounted, there is a support with a long inclined arm, which serves as a support and pivot bearing on a shaft, provided at its upper end with a flywheel or knurled wheel, which remains tangent and in permanent contact with the surface of the conical container of the concrete mixer, while at its lower end, said axle is integrally mounted a gear cogged, which gear in a pinion, whose axis is driven by the set of reduction gears, transmitters of the driving force of the driving means, so that by the friction of the above mentioned grooved wheel, on the body of the concrete mixer, it is forced to turn, whether the tilting box is horizontal or inclined.
