Abstract: An armrest according to one embodiment of the present invention includes a case including a passage which guides a flow of air while the air is introduced and discharged and a through-hole which is formed via the passage to allow the air to be discharged outward, a fan located inside the case and by which the air is introduced and discharged through the passage, a heating element configured to supply heat to the air discharged by the fan and an outer surface of the case, and a supporter configured to support an external force applied to the case in at least two directions to keep a shape of the case.

Abstract: The objective of the present invention is to provide: a tray for an ice making machine which has low heat capacity without requiring surface treatment such as silicon coating and the like; an ice making machine comprising the same; and a refrigerator comprising the ice making machine. The tray for an ice making machine, according to the present invention, which has an inner space capable of accommodating liquid, comprises: a first case which is formed from sheet metal and has a hollow partition for dividing the inner space; and a second case which is formed from resin, wherein the second case is formed by insert injection of the resin into the first case so that the first case and the second case are coupled so as to be superimposed on each other.
