Disclosed is a folding floatation device that is folded at the time when an amphibious vehicle is driven on the water, thereby providing improved safety and increased driving speed to the amphibious vehicle and a method for providing additional buoyance to the amphibious vehicle at the time of driving on the water by using the folding floatation device. According to the present invention, there are provided a folding floatation device with the lower portion opened, a folding flotation device with the upper portion opened and a closed folding flotation device, each of which is disposed at an appropriate location of the vehicle body, such that each floatation device is folded during driving on land and unfolded only during driving on the water, thereby providing additional buoyance to the amphibious vehicle. Therefore, the floatation device of the present invention can provide improved performance to existing amphibious vehicles and overcome design limitations on the driving on the water in case where a novel model is developed, thereby providing a high performance vehicle. With a method for embodying the folding floatation device with the lower portion opened in a space of a suspension device, more particularly, a water driving speed in a track driving manner can be enhanced over that in a water jet driving manner.
