1. A propeller apparatus of an air mobility, the propeller apparatus comprising:
a wing composed of a fixed part and a rotation part deployed from or folded on the fixed Part;
a hinge mechanism rotatably connected to the fixed part and the rotation part to have a first rotation center of the fixed part and a second rotation center of the rotation part, and providing an elastic force such that the rotation part is folded while being rotated toward the fixed part;
a movable bar spaced apart from the hinge mechanism to be movably provided, and having a third rotation center selectively matched with the first rotation center and the second rotation center according to a movement position of the movable bar; and
a driving mechanism installed on the fixed part and the rotation part, connected to the movable bar, allowing the third rotation center of the movable bar not to be matched with the first rotation center and the second rotation center when the rotation part is deployed, and moving the movable bar to allow the third rotation center of the movable bar to be matched with the first rotation center and the second rotation center upon a request for folding of the rotation part, such that the rotation part is rotated by the elastic force of the hinge mechanism.
