Abstract of the disclosure A modular wheel made of plastic material for a children's vehicle with a pedal-driven wheel consisting of two half-wheel. Each half-wheel comprises a hollow, peripheral portion, having a semicircular radial section and being connected to a central disc portion; a first hollow shaft extending outwardly from said central disc portion; a radial arm integral with said first hollow shaft, and, in its outer end, with a sleeve, having an axial hole parallel to the axis of the first hollow shaft; a second hollow shaft connected to a pedal crank, which is rotably received in said axial hole. Said central disc portion includes an opening facing said radial arm and having a shape complimentary thereto in order to permit the moulding in a single step of each semi-wheel. Each half-wheel has, in its internal face, male members and female members apt to connect the half-wheels with each other. According to the present invention the wheel can be moulded in two parts identical to each other produced by means of only one die in only one moulding process. The mounting of the wheel and of the pedal crank is rapid; these is no need of fins, washer, screws and other articles of metallic carpentry; as a result the wheel according to the present invention cannot rust and is less expensive than the known types of wheels.
