    摘要： A damping device includes a damper provided to an outer end of a stacker crane in a traveling direction. The damper includes: a rod member extending along the traveling direction; a first biasing member configured to bias the rod member outward in the traveling direction; and a movement restriction mechanism configured to allow inward movement of the rod member in the traveling direction and restrict outward movement of the rod member in the traveling direction when the rod member has moved inward in the traveling direction.
