Abstract: A refrigeration compartment door for refrigerators, provided with a door duct capable of introducing cool air to the interior of a refrigeration compartment, is disclosed. The door includes a main body having an insulating layer therein and a door duct provided in the insulating layer. Also, the door duct has at least two more branch ducts, so cool air, introduced from a cabinet of a refrigerator to the door duct, is separately introduced into the branch ducts. An insulating member is mounted to the door duct and has a plurality of first discharging holes in order to allow the cool air to be discharged into the interior of the refrigeration compartment passing through the door duct. Thus, a wide temperature difference between the interior of the refrigeration compartment and the door duct is reduced by the insulating member.
