Assembly type wind force car for teaching tool

The present invention, is formed on the upper surface side and the interior of the mast installation section 11 through the vertical, the other is formed on the upper surface and the interior of the vehicle johyanggi installation section 12 through the vertical mast installation (11) formed between the vehicle johyanggi installation section 12 and a vehicle body 10 provided with a sail johyanggi installation section 13 has a groove semicircular; And mast installation section 11 dotdae holder 21 to be inserted into, dotdae the mast (22) rotatably mounted on a holder 21, which is installed forms a predetermined interval along the longitudinal direction of the mast 22 at least two or more boom 23, a sail assembly 20 including a sail (24) provided between the boom 23; A handle (31a) formed in the upper end portion and a steering board (31) is equipped with a rear mounting part (31b) formed at the lower end on, rotatably borne a steering ground earth 33 to the vehicle johyanggi installation portion 12 and the , having a rear wheel (32) fitted rotatably to the rear mounting part (31b) johyanggi vehicle (30); In that it comprises a rear wheel 32 is formed a front wheel 50 which is rotatably borne a shaft (S) to the outer surface of the other side of the vehicle body 10 is characterized. According to an embodiment of the invention, an elementary school or spring junior high school students were made to wind car directly using the respective members fabricated in byeolmul, which can by easily understand the operating principle and structure of the wind power car, and further, making the wind-car towards the sail forward, backward, when, as a side blow directly at various locations on the sails either as spring the big powers will receive passes, and thus the synthesis and the lift force through a variety of experiments to whether any symptoms occur the principles of science, such as the advantage that you can clearly deliver more for elementary and middle school students.
