In a transportation device (T) which transports a workpiece (W), a chuck (H) which is capable of holding and releasing the workpiece (W) is provided on the tip end of an arm (A) that is capable of expanding and contracting. A moving/swinging mechanism (M) is provided for moving the arm (A) horizontally and swinging the arm (A) in the movement direction, and hence the workpiece (W) can be transported to and from a workbench (B 1, B 2 ) above which an obstruction exists.
