a first door disposed in front of the main body and having an opening; a second door disposed in front of the first door to open and close the opening of the first door; and a latch device configured to couple or separate the second door to or from the first door, wherein the latch device comprises: a fixing member disposed on the first door; a locking member provided on the second door to be coupled or separated from the fixing member; and an input member provided on the second door to be rotatable in the left and right directions, and wherein the locking member rotates in a direction of being separated from the fixing member when the input member rotates in the left direction, and the locking member rotates in the direction of being separated from the fixing member when the input member rotates in the right direction. ### Claim 2 (depends on 1) The refrigerator according to claim 1, wherein: the latch device further comprises a latch case disposed on the second door; the locking member is coupled to the latch case to be rotatable with respect to a first rotation axis; and the input member is coupled to the latch case to be rotatable with respect to a second rotation axis. ### Claim 3 (depends on 1) The refrigerator according to claim 1, wherein: the locking member comprises a locking protrusion formed at one end close to the fixing member and a receiving protrusion formed at the other end close to the input member; and the input member comprises a first pressing portion configured to press the receiving protrusion when the input member rotates in the right direction and a second pressing portion configured to press the receiving protrusion when the input member rotates in the left direction. ### Claim 4 (depends on 3) The refrigerator according to claim 3, wherein the receiving protrusion comprises a receiving roller rotatably provided on a portion coming into contact with the first pressing portion or the second pressing portion. ### Claim 5 (depends on 3) The refrigerator according to claim 3, wherein at least one of the first pressing portion and the second pressing portion comprises an input roller rotatably provided on a portion coming into contact with the receiving protrusion when the input member rotates. ### Claim 6 (depends on 2) The refrigerator according to claim 2, wherein the latch device further comprises an elastic member configured such that one end thereof is fixed to the latch case and the other end opposite to the one end is fixed to the locking member to press the locking member in a direction of being coupled to the fixing member. ### Claim 7 (depends on 2) The refrigerator according to claim 2, wherein the second door further comprises a latch cover forming an accommodation space in which at least a portion of the latch case is accommodated. ### Claim 8 (depends on 7) The refrigerator according to claim 7, wherein the latch case comprises a cover portion to cover the accommodation space of the latch cover. ### Claim 9 (depends on 8) The refrigerator according to claim 8, wherein the cover portion is formed to cover a portion of the second door to which the latch cover is coupled. ### Claim 10 (depends on 9) The refrigerator according to claim 9, wherein the cover portion comprises a through hole formed in a size and shape corresponding to the input member so that the input member passes therethrough. ### Claim 11 (depends on 7) The refrigerator according to claim 7, wherein the latch case is provided to be screwed to at least one of the latch cover and the second door. ### Claim 12 (depends on 2) The refrigerator according to claim 2, wherein the first rotation axis extends in a direction different from the second rotation axis. ### Claim 13 (depends on 12) The refrigerator according to claim 12, wherein the first rotation axis extends in a direction perpendicular to the second rotation axis. ### Claim 14 (depends on 1) The refrigerator according to claim 1, further comprising a door handle installed on the second door and disposed in front of the latch device to be spaced apart from the latch device. ### Claim 15 (depends on 1) The refrigerator according to claim 1, wherein the input member is disposed to protrude from a front surface of the second door.
