A refrigerator may include a body including a first insulating panel having a first coupler and a second insulating panel having a second coupler, wherein the first coupler and second coupler are coupled together, a compartment inside the body, a door to open and close the compartment, and a cooling device to cool the compartment, wherein the first insulating panel, first coupler, second insulating panel, and second coupler are configured so that, to couple the first coupler and second coupler together, the first insulating panel and first coupler are movable in a first direction toward the second insulating panel and second coupler so that the first coupler and second coupler become engaged, and, after the first coupler and second coupler are engaged, the first insulating panel and first coupler are movable in a second direction perpendicular to the first direction so that the first coupler and second coupler become coupled.
