A moving system for structures includes a linking unit located between first and second structures that can move in a first direction. A drive unit is connected to the first structure, and the first and second structures are connected. The second structure moves along the first direction when the drive unit moves the first structure along the first direction. The linking unit has a first part located on the side of the first structure and a second part located on the side of the second structure. The first and second parts line up along the first direction. The first part can shift toward the second part in a second direction different from the first direction without moving along the first direction, and the second part can shift toward the first part in the second direction without moving along the first direction.
