Abstract
A storage section for storing a video monitoring equipment for an airliner and the video monitoring equipment which moves to a visible position are connected by two long cylindrical springs. One of the springs is urged in the direction of the storage section of the airframe. The other spring is made of a shape-memory alloy on which a specific shape is memorized in heated condition. When the second spring is heated and takes the specific shape, the video monitoring equipment is moved to the visible position together with the move of the second spring going against the urging force of the first spring. When the heating of the second spring is stopped, the video monitoring equipment is moved to the storage section along with the movement of the first spring by the urging force of the first spring.
