The embodiment of the invention provides an arm device and a rotorcraft, and belongs to the technical field of aircrafts. The engine arm device comprises an engine arm base, a motor base, a first fixing piece and a second fixing piece. The arm base is used for being connected with a fuselage of the rotorcraft. The arm seat comprises a first mounting part and a second mounting part which are oppositely arranged. A first mounting hole is formed in the first mounting part; and a gap is formed between the first mounting part and the second mounting part. The motor base is used for installing a power device, and a fixing hole is formed in the motor base. The first fixing piece sequentially penetrates through the first mounting hole and the fixing hole, and the first fixing piece is connected with the second mounting part. The second fixing piece is connected with the first fixing piece in a matched mode so that the motor base can be fixedly installed in the gap. The motor base is stably and firmly mounted on the arm base through the cooperation of the first fixing piece and the second fixing piece, so that the rotor craft flies more safely.
