1. A refrigerator comprising:
a main body; a storage chamber provided in the main body so that a front surface thereof is open; an internal door rotatably provided at the front surface of the main body so as to open and close the storage chamber and having an opening part in which a plurality of door guards are provided; an external door rotatably provided at a front surface of the internal door so as to open and close the opening part; and an internal door opening prevention device to allow or prevent opening of the internal door according to whether the external door is opened or closed, wherein the internal door opening prevention device comprises
a stopper coupled to a lower portion of the main body;a locking part rotatably coupled to a lower portion of the internal door and rotated according to whether the external door is opened or closed so as to be locked and unlocked with the stopper;a spring configured to elastically support the locking part;a cover configured to cover the locking part so as to prevent the locking part from being exposed to an outside and having a rotational protrusion to which the locking part is rotatably coupled; anda protruding part coupled to a lower portion of the external door, the protruding part being configured to be in contact with the locking part and thus to rotate the locking part to be unlocked from the stopper when the external door is in a closed position,wherein when the external door is in an open position, the protruding part is configured to not be in contact with the locking part whereby the locking part is elastically rotated by the spring to be locked to the stopper.
