Abstract
A stacker crane includes a traveling assembly including a drive wheel being at least one of a first wheel and a second wheel opposing each other across a rail and a mover to move the drive wheel, the first wheel, and the second wheel. The mover includes first and second contact pressure adjusters to adjust a contact pressure of the drive wheel against the rail by moving the drive wheel to cause the first wheel and the second wheel to move farther away from or closer to each other. One of the first and second contact pressure adjusters is on one side of the drive wheel in a traveling direction of the traveling assembly, and the other of the first and second contact pressure adjusters is on the other side of the drive wheel in the traveling direction.
