Abstract: An ice maker of a refrigerator includes an upper assembly having an upper tray that defines upper portions of a plurality of spherical ice making chambers. The ice maker also includes a lower assembly located vertically below the upper assembly and configured to rotate relative to the upper assembly about a rotation shaft and having lower tray that defines lower portions of the plurality of spherical ice making chambers. The ice maker also includes a lower ejector unit that is located vertically below the lower tray and that is configured to, based on the lower assembly rotating away from the upper assembly, push the lower tray through the lower support to thereby discharge the ice piece from the ice making chamber. The lower tray includes a deformable portion at each of the plurality of spherical ice making chambers that is configured to be pushed by the lower ejector unit.
