The invention provides a refrigerator capable of preventing careless opening of other doors in the door opening and closing operation by users. According to the refrigerator 1 provided by the invention, when the users open a door 8 of a refrigerating chamber 3, a control device 34 can set a shielding device 50 in a closing state. An opening between a fan baffle plate 51 and an induction guide pipe 59 can be closed to stop a channel between a refrigerating chamber supply air flue 14 and a freezing chamber 4A. Cold air currents flowing by the refrigerating chamber 3 and the refrigerating chamber supply air flue 14 can be stopped at the fan baffle plate 51 and the induction guide pipe 59. As an air supply port 13a of a cooling chamber 13 is closed by the fan baffle plate 51, a channel between a reflux air flue 20 and the freezing chamber 4A is stopped. Even if the door of the refrigerating chamber 3 is closed after opening, cold air in the refrigerating chamber 3 can be inhibited from flowing into the freezing chamber 4A along with the actions so as to prevent careless opening of a closed door 9 of the freezing chamber 4A.
