<p>PROBLEM TO BE SOLVED: To provide a vehicle which enables a propeller to be used as a bumper, prevents running characteristics on the ground from being impaired, and enables both ground running and aerial flight.SOLUTION: A vehicle includes: a vehicle which has a power source and is run by the power source; a propeller including a rotary shaft, which is provided in at least one of a front part and a rear part of the vehicle and rotated around an axis set along a running direction of the vehicle by the power source, and a first blade and a second blade which extend from the rotary shaft in a radial direction of the axis; and aerofoils which are provided at the vehicle and generate lift force when the vehicle moves forward. The first blade may selectively move between a first position where the first blade extends from the rotary shaft in a direction opposite to an extension direction of the second blade and a second position where the first blade extends in the same direction as the extension direction of the second blade.</p> |
