The present invention relates to a vehicle-mounted wing device to improve fuel economy by reducing vehicle weight. More specifically, the present invention is a vehicle-mounted wing device to improve fuel economy by reducing vehicle weight, comprising: a streamlined wing body whose upper side is circular shaped and lower side has a flat structure compared to the upper side; and a coupling clamp member fixed and installed on the lower side of the wing body and fixedly coupled to a connecting member installed on a roof of the vehicle. The wing body is characterized to work in the way that vehicle weight decreases by upward force created by the flow of air approaching the upper side and the lower side of the wing body when a car moves at a high speed under the condition that the wing body is installed on the roof of the vehicle by the coupling clamp member. According to the vehicle-mounted wing device to improve fuel economy by reducing vehicle weight, as the wing body is installed to be able to create upward force in the roof of a vehicle, the weight of a vehicle is decreased by upward force which occurs in a wing body along the flow of air approaching while a vehicle runs at high speeds and fuel economy is improved through the following decrease of fuel consumption. Besides, as the wing body is installed on the roof of a vehicle, and is designed in the way for the wing body to cover an entire roof of a vehicle, indoor temperature of a vehicle can be prevented from increasing through a roll-up shade effect. |
