A refrigerator includes a first combining (210) member arranged on a side (11) of a cooling room such that the side of the cooling room and a side (121) of a evaporator are hooked with each other in a first direction (210) and a second (220) combining member arranged on the side of the cooling room, the other side of the evaporator is inserted into the second combining member in a second direction, which is different from the first direction, to combine the other side of the evaporator and the one side of the cooling room. Assembly performance is improved with a combining member that facilitates an evaporator to be combined onto an inner side of a cooling room, and heat exchanging performance is improved by the combining member enabling the evaporator to be combined onto a side of the cooling room with a gap.
