A refrigerator including an icemaker and an ice bucket provided at a door, a feeding unit to feed ice cubes stored in the ice bucket, a driving motor provided at a main body to drive the feeding unit, and a coupling device to transmit driving force from the driving motor to the feeding unit. When the door is closed, the driving motor is connected to the feeding unit. When the door is opened, the driving motor is disconnected from the feeding unit. Accordingly, the door has a simple structure, the ice bucket has an increased capacity, repair or replacement of the driving motor is easily achieved. The coupling device includes a first coupling unit and a second coupling unit which is engaged with the first coupling unit to receive driving force. The coupling device is configured to hide the coupling units when the door is opened.
