PROBLEM TO BE SOLVED: To eliminate generation of inclination of an L-shape roof by difference of a delivery flow rate of an operation oil even if each independent hydraulic device is connected to a plurality of hydraulic cylinders for opening/closing the L-shape roof in a wing vehicle. SOLUTION: The roof opening/closing control device for the wing vehicle is provided with a plurality of hydraulic cylinders 11L, 12L for opening/closing the roof 10L of the wing vehicle; the hydraulic devices 15L, 16L for each independently delivering the operation oil to the hydraulic cylinders 11L, 12L; and a biaxial angle sensor 13 installed at a center of the roof. Angle information of the roof is input from the biaxial angle sensor 13, and a control device 17 controls a delivery amount of the hydraulic devices 15L, 16L based on the angle information and synchronizes the expansion/contraction amounts of the plurality of hydraulic cylinders 11L, 12L.
