The cross tube includes: curved pipe parts (37) located closer to corresponding end portions (31) of the cross tube than corresponding attached portions (35) of the cross tube, the attached portions being attached to the airframe; and a middle portion (32) located at opposite sides of the curved pipe parts (37) across the attached portions. The stiffening portion is arranged in at least one of internal spaces of pipe parts that are the curved pipe parts (37) and a pipe part located between the pair of curved pipe parts (37).
