Beschreibung
Zusammenfassung:	An ice tray may include a control box; a motor unit installed in the control box, and generating a rotational force; a gear group receiving the rotating force of the motor unit, and including one or more gears having a gear ratio through which a rotational speed by the rotational force is changed, and an output unit engaged with the one or more gears and transferring a speed-changed rotation to the outside of the control box; and an ice tray having one side connected to a connection shaft extended from the output unit of the gear group, and rotated by a final number of rotations transferred through the output unit, where the one side of the ice tray has a larger rotation angle than the other side of the ice tray. The output unit may receive the rotational force through one or more gears, and include first and second output units which are formed as different modules so as to be rotated through two gear ratios. The rotation centers of the first and second output units may be positioned on the same axis, and the first and second output units are formed in different rotation sections.
