Claim:
An icemaker comprising: a rotatable ice tray with at least one column of ice making chambers formed therein to make ice; an ejector rotatably provided in each ice making chamber to eject the ice formed in the ice making chamber; an operation device which rotates the ice tray; and a separation device which separates the ice from the ice tray; wherein the ejector includes: a shaft rotatable along a longitudinal direction of the ice tray; at least one ejector fin projected on the shaft at a predetermined distance to eject the ice of the ice tray as the shaft rotates; and an inertial operation part which generates rotational force due to its weight when the ice tray rotates, to relatively rotate the shaft with respect to the ice tray, the inertial operation part having a weight and an arm having an end connected to an end of the shaft and the other end connected to the weight.
