  • Publication number: 20250263097
    Abstract: A holding unit of a transport vehicle is coupled to the travel unit via a coupling mechanism. The coupling mechanism is configured to be able to transition between a coupled state in which the travel unit and the holding unit are coupled to each other, and a separated state in which the travel unit and the holding unit are separated from each other. The travel unit executes both a coupled traveling mode of traveling while being coupled to the holding unit via the coupling mechanism and a separated traveling mode of traveling alone while being separated from the holding unit.
