A structure capable of efficiently improving the fuel consumption of a running body such as a running vehicle, comprising a fan shaft (23) disposed generally in vertical direction relative to the running direction (X) of the running body (1), fans (21) fixed to the fan shaft (23) and rotating the fan shaft (23) by receiving a head wind, propeller shafts (43) disposed generally in parallel direction relative to the running direction (X), transmission mechanisms (30) connecting the fan shaft (23) to the propeller shafts (43) and transmitting the rotating force of the fan shaft (23) to the propeller shafts (43), and propellers (41) fixed to the propeller shafts (43). |
