Abstract
The present invention provides a balloon-shaped structure driving apparatus by which portions of a balloon-shaped structure can be caused to move easily and reliably and weight and cost can be reduced and a discharge/suction selector valve device. A rotating blade of the discharge/suction selector valve device is rotated to a suction operating position to connect an air outlet and an air flowing hole, to exhaust air from actuators toward a pump device, and to contract a bellows portion. At this time, the actuators pull acting portions of arm portions of a balloon robot main body, the balloon robot main body is bent at allowance portions which can be bent, and the arm portions are forcibly moved down.
