To provide a wing opening/closing device for a wing vehicle capable of closing a wing in an emergency where a wing cannot be closed.SOLUTION: A wing opening/closing device comprises: a male screw shaft 12 rotatably supported in a cylinder 11; a female screw body 13 which is screwed to a male screw shaft and linearly moves with rotation of the male screw shaft; a piston 14 fixed to the female screw body; a motor 16 for driving the male screw shaft so as to rotate via a reduction gear 15; and a base 17 holding the reduction gear and the motor. The base and the piston are respectively pivoted on a body 3 and a wing 5 of the wing vehicle. A coupling body 20 is fixed to the piston, a bearing hole 22 is formed in the coupling body, and a coupling shaft 24 is rotatably fitted into the bearing hole, and between the coupling shaft and the coupling body, a U-shaped pin 28 is installed so as to be freely withdrawn.SELECTED DRAWING: Figure 2
