Ratchet device with automatic return for toys which is characterized in that it comprises a gear wheel that receives the movement of the toy motor group whose wheel is mounted freely on an axis and pressed axially by a helocoidal spring against a ratchet formed by several curved blades whose bent ends coincide and are retained in angular position of couplings in holes appropriately distributed circularly on said wheel so that when there is a torque on the shaft that is antagonistic to the rotation of the gear wheel, said axis rotates at the same angular speed as this and when the axis has a higher rotation speed than said wheel, the decoupling between the ratchet and the wheel occurs.
