Abstract
A device for transmitting drive force to an ice-making tray of an ice making machine includes a slider interposed between a drive motor gear and a gear directly connected to the ice-making tray, and a cam gear meshing with the drive motor gear. The slider is formed with a gear portion meshing with the gear directly connected to the ice-making tray for rotating same both clockwise and counterclockwise, and a guide groove receiving therein an actuating pin formed in the cam gear for moving the slider in pivotal movement in a predetermined range of angles. Rotational movement of a drive motor can be converted into clockwise and counterclockwise rotational movements of the ice-making tray by the guide groove cooperating with the actuating pin, and a twisting movement and a countertwisting movement can be imparted to the ice-making tray by the conjoint actions of the slider, cam gear having the actuating pin, gear directly connected to the ice-making tray and bent rise portions formed in a frame, so that the ice cubes formed in the ice-making tray can be automatically released therefrom.
