The invention provides a lift door device, which can prevent maintenance personnel from accidentally entering an entrance and exit at a landing where a lift car is not stopped without becoming hindrance when passengers get on and off the lift car. The door device is provided with a landing door (22), an interlocking device (28), an entry prevention device (35), and an operation device (40). The operation device (40) is provided with a connection member (41), a displacement member (42), and a transmission mechanism (43). The connection member (41) can be disposed at a first position, in which the connection member (41) protrudes from the end surface of the landing door (22) and is connected to the entry prevention device (35), and a second position, in which the connection member (41) is separated from the entry prevention device (35) and does not protrude from the end surface of the landing door (22). When the displacement member (42) is displaced, the transmission mechanism (43) displaces the connection member (41) disposed at the first position to the second position.
