    (54) Pivot-wheel coupling device for wheeled toys, particularly model automobiles


    (57) A pivot-wheel coupling device for wheeled toys, particularly for model automobiles, comprising a pivot rigid (2) with the automobile floor (1) and having a preferably hemispherical head (8), and a wheel (10) having a hub (11) with a frusto-conical bore (15) arranged to receive said pivot (2), and wherein the pivot comprises at the base of the head a collar of trapezoidal cross-section (9), the wheel comprising a cylindrical cavity (18) into which the frusto-conical bore (15) of the hub (11) opens, said cavity having a diameter greater than the forward end of the frusto-conical bore to thus form a step (19) against which the collar of trapezoidal cross-section abuts when the wheel has been coupled to the pivot.
