Abstract: A refrigerator has an icemaker that includes a partition arm extending from the outside of the ice making tray into the ice making tray, the partition arm constituting a part of an ice compartment structure to define ice making cells. When the ice making tray is rotated in a given direction, the ice making tray allows ice to be separated from the ice making cells by being twisted by the partition arm. When the ice making tray is rotated in an opposite direction, the ice making tray allows the ice still present in the ice making cells to fall from the ice making cells by interference with a rotation stopper formed at the partition arm.
