A moulded wheel made of plastic material for children's vehicle with pedal-driven wheels, consisting of two identical half-wheels (1a, 1b) separated by the symmetry plane perpendicular to the axis (X-X) of the wheel and formed by a she element produced by only one moulding process and by means of only one die and back draft, and including a hollow, peripheral torus portion (2) which has a semicircular radial section and is connected to a central disc portion (3) from which a short, hollow shah (4) projects outwards and is integrated with a box-like radial arm (5) integrated in turn at its external end with a sleeve (6) which is provided with a hole (6a) having an axis (Y-Y) parallel to the axis (X-X) of the wheel, and in which the hollow shaft (7) of the pedal crank (8) is fitted, from the internal face of each half-wheel (1a, 1b) at least one guide pin (10) and one guide seat (11) projecting at positions diametrically symmetric with respect to the axis (X-X) of the wheel and at least one fixing means (12) and one housing means (13) projecting at diametrically opposed positions.
