Publication number: 20130307398Abstract: A refrigerator includes a rotating bar configured to seal a gap between one pair of doors. The rotating bar includes a case provided with an accommodating space therein while having one surface thereof open, a heat insulation member accommodated in the accommodating space, a cover configured to cover the one surface of the case that is open, and a metallic plate being coupled to an outer side of the cover. The cover includes a heat conduction blocking part being protruded to both sides of the metallic plate while having a bent-shape cross section so as to prevent heat from being transmitted to both side surfaces of the rotating bar after being heat conducted along the metallic plate.Type: ApplicationFiled: July 25, 2013Publication date: November 21, 2013Applicant: SAMSUNG ELECTRONICS CO., LTD.Inventors: Sung Mo Kim, Jee Hoon Lee, Myoung Hun Kim, Hak Gyun Bae, Hee Tae Shon, Jong Hoon Oh, Sinn Bong Yoon, Kun Eui Hong
