Abstract
A transport vehicle that transports a container while being suspended includes a lateral swing suppression device configured to abut against an outer side surface of the container that is suspended and held, and suppress a lateral swing of the container. The lateral swing suppression device includes an abutment roller configured to rotatably abut against the outer side surface of the container. A concave groove extending continuously over an entire periphery of an outer peripheral surface of the abutment roller is formed in a region corresponding to a convex portion of the container.
