Improvements in the construction of dancing tops without cord, comprising a manually adjustable portion, an elongated shaft held free, rotating and vertically within said portion, said shaft having at least one end section projected to the outside of said portion a rotor secured to said tree and rotating with it within said portion, endowed with a moment of inertia capable of maintaining the angular momentum of said tree for considerable periods of time; and a friction roller secured to said externally projecting end section of the shaft, whose friction roller is of substantially smaller diameter than the said rotor, so that after a rapid rolling of said roller on a rigid surface, the rotor will rotate to a peripheral speed substantially greater than that of the friction roller.
