PROBLEM TO BE SOLVED: To provide a wing body structure quickly and easily locking and releasing the opening of a wing roof and firmly retaining the locked state. SOLUTION: A link member 30 moving between a first position and a second position for engaging and releasing a lock device 32 by the contracting and extending operation of a hydraulic cylinder 26 is fitted to the wing roof 22. The engagement between an engagement part 44 of the link member 30 and the lock device 32 is released by moving the link member 30 to the second position by the extending operation of the hydraulic cylinder 26 so that the wing roof 22 is opened. On the other hand, the wing roof 22 is closed by contracting operation of the hydraulic cylinder 26. This wing body structure is so constituted that, when the link member 30 is moved to the first position and the wing roof 22 is completely closed, the engagement of the engagement part 44 of the link member 30 to the lock device 32 is completed. |
