The present invention relates to an educational apparatus using a miniature car. As shown in a text book of FIG. 2, a student makes a structure similar to a kind of anemoscope to understand the relation between wind and energy. Although a toy of a wind powered vehicle has been developed, the wind-powered vehicle has a complex gear structure and a shaft structure for driving the wheels of the vehicle by wind power. The operation is complex and the price is high, so that it is difficult to use the wind-powered vehicle as a studying material. The present invention includes a driving part and a control part which are installed to a body part having a thin plate structure. The driving part is formed of a paper or a thin plate of synthetic resin plate which may be usually obtained by a student and a driving wheel used as a wheel is formed of a structure for fixing a mast. Thus, the assembly is easily performed and the vehicle is suitably driven while a sail directly receives wind to move in all directions. In addition, a width of the sail of the present invention may be arbitrarily controlled, so that it is easy to directly experience the effective using of wind power and the operation of the wind powered vehicle while observing all variations in a size and a position of the sail and a direction of wind. |
