A flag pole device includes a pole, an upper rotary barrel and a lower rotary barrel rotatably mounted on the pole for securing a flag, and a connection rod connected between the upper rotary barrel and the lower rotary barrel. The upper rotary barrel and the lower rotary barrel each have a side column at the periphery, which has a through hole for receiving the connection rod. The connection rod has opposing flat top and bottom end portions disposed in the same plane and respectively inserted through a flat bottom hole portion of the through hole of the upper rotary barrel and a flat top hole portion of the through hole of the lower rotary barrel and positioned in a respective crossed hole portion and stopped at a respective step in the side column of the upper rotary barrel and the side column of the lower rotary barrel, assuring synchronous rotation of the upper rotary barrel and the lower rotary barrel and avoiding tangling of the flag on the pole.
