Abstract: A toy windmill having a special mounting system as described, the windmill being of the type normally comprising one or more sheets of plastic, paper of the like, having an orifice in the center thereof for receiving the windmill shaft. The sheet or sheets define a plurality of blades having free ends which are also provided with orifices. When the windmill is mounted, said blades are doubled over themselves so that the orifices in their ends coincide and the shaft passes therethrough to define the final shape of the windmill. After this, the blade ends are mounted on the shaft by a ring formed by two releasably cooperating engagement portions for retaining the ends of the blades therebetween.
