摘要：
A coupling device that couples with a cart includes a coupling portion that couples with the cart, a base portion that guides the coupling portion, and a driving motor that drives the coupling portion. The driving motor drives and controls the coupling portion so as to be changeable among a first state in which the coupling portion is housed, a second state in which the coupling portion is capable of coupling with the cart, and a third state in which the coupling portion couples with the cart. With the coupling portion and a side frame of the cart facing each other, the coupling portion changes from the second state to the third state, thereby causing the coupling portion and the side frame to be coupled to each other.
