According to one embodiment, a moving body includes an electrical component, a base frame that includes caster portions provided to be runnable on a floor surface, and is formed such that a front side is narrower than a rear side along a front-rear direction, the rear side is opened, and thus another moving body is insertable from the rear side, and a battery case that accommodates a battery supplying power to the electrical component and has an opening and closing lid opening rearward. A restricting member is provided inside the base frame and restricts a position of the other moving body inserted from the rear side to a position where the opening and closing lid opens at least to an angle at which the battery in the battery case is replaceable.
