The propeller includes one of a first body and a second body. The motor includes another one of the first body and the second body. The locking mechanism includes a coupling member including a femoral position groove, a fastener configured to fix the coupling member to the second body, and a locking member configured to lock the first body to the coupling member and the second body. A bottom portion of the first body that contacts the coupling member includes a protruding rib configured to fit with the femoral position groove to restrain the first body from rotating relative to the coupling member.
