In a stacker crane, a cover to cover an elevation area of an elevation portion is integrally attachable to side surface portions of a mast, which includes a reinforcement portion and an adjuster. The reinforcement portion between a pair of the side surface portions in a Y direction extends toward an opposite direction to an elevation surface of an elevation surface defining portion and has a higher stiffness than that of each of the pair of side surface portions. The adjuster is spaced from the elevation surface defining portion in an X direction perpendicular to a Z direction and the Y direction, and both edges thereof extendible in the Y direction are contactable with the reinforcement portion and each of the pair of side surface portions.
