PROBLEM TO BE SOLVED: To provide a wing door opening/closing device which facilitates mounting work and has excellent maintainability. SOLUTION: Characteristically, this wing door opening/closing device is equipped with a base frame 14, a drive mechanism 13 which is provided in the base frame 14, a crank arm 12, one end 12a of which is mounted on a wing door 105 and the other end 12b of which is rotatably journaled on the base frame 14, and a coupling means 20 for coupling the drive mechanism 13 with the crank arm 12; the drive mechanism 13 comprises a drive motor, a slider 19 which is coupled with the coupling means 20, and a transfer mechanism which transfers the revolutions of the drive motor so as to move the slider 19; the coupling means 20 converts the advance/retreat of the slider 19 into the rotating operation of the crank arm 12; the base frame 14 is fixed to an upper part of a loading space 102; and the normal/reverse revolutions of the drive motor make the crank arm 12 rotated to open/close the wing door 105.
