[2-2. Action]
When the vehicle body 1 travels, traveling wind received by the vehicle is generated. This traveling wind is received from the air inlet 10A of the opening 10 of the wind receiving device 2A. The received traveling wind hits the blade 8 of the impeller 6, and the blade 8 rotates the impeller 6 in the direction opposite to the rotation of the wheel when the vehicle moves forward.

[2-3. effect]
According to the present embodiment, the wind receiving device 2A and the wind receiving device 2B give a lift force in the direction of offset to the vehicle main body 1, and the load received by the vehicle due to the lift force of the wind receiving device can be suppressed. Therefore, it is possible to provide a vehicle with a power generation device that is less likely to become unstable in driving.

(2) The wind receiving device 2 </ b> B may be installed on the roof of the cargo compartment of the vehicle main body 1, and the wind receiving device 2 </ b> A may be installed on the bottom of the vehicle main body 1. By arranging in this way, the wind receiving devices 2A and 2B give the lift in the direction of pulling the cargo compartment to the outside by the traveling wind, so that the lift applied to the cargo compartment of the vehicle main body 1 can be reduced.

(3) As shown in FIG. 6, the number of wind receiving devices 2 </ b> A or 2 </ b> B installed at the bottom of the vehicle body 1 is increased from the number of wind receiving devices 2 </ b> A or 2 </ b> B arranged on the cargo compartment roof of the vehicle body 1. You may do it. Due to the viscosity of the air, the speed of the traveling wind at the bottom of the vehicle is slower than the rooftop speed of the vehicle. For this reason, the lift received by each wind receiving device is smaller in the wind receiving device installed at the bottom of the vehicle body 1 than in the wind receiving device arranged on the roof of the cargo compartment. This unbalance of lift is suppressed by increasing the number of wind receiving devices 2A or 2B installed at the bottom of the vehicle body 1 from the number of wind receiving devices 2A or 2B arranged on the roof of the cargo compartment of the vehicle body 1. Therefore, it is possible to provide a vehicle with a power generation device in which driving of the vehicle is less likely to become unstable.

(4) The wind receiving device 2 </ b> A or 2 </ b> B may be installed on a bottom portion that is not an overhang portion at the rear of the rear wheel of the vehicle body 1.
