<P>PROBLEM TO BE SOLVED: To arrange rotary blades axially along the rotating shaft of a generator because of the great occupation of a space body inside and outside a vehicle if the rotary blades serving as the motive power of the generator through the wind force of self-propelling to always replenish electric power to the storage battery of an electric vehicle are arranged at a right angle to the rotating shaft of the generator like an electric fan. <P>SOLUTION: A truncated cone drum 7 with a diameter small at an air inflow port and large in front of a wind turbine generator is mounted to the rotating shaft (a square steel bar) 8 extended from the generator 11 in a duct 5 mounted to the roof of the electric vehicle. The truncated cone drum and the blades 6 on the drum are molded as one fusion-united body out of reinforced plastic to attain weight reduction. Further, resin is injected through pores provided in the drum to be bonded to the square steel bar. The strength of the rotating blades is thereby enhanced to withstand high-speed wind pressure, to improve the rotating ability of the wind turbine generator and to replenish electric power to the storage battery. <P>COPYRIGHT: (C)2010,JPO&INPIT |
