A lift door anti-falling device (6) and a lift door device (1) with the same are disclosed. The lift door device (1) includes a flat plate portion (31) set along the inner wall (X4) of a structure body (X) for a lift well, guide rails (41) set on the inner surface of the flat plate portion (31), rollers (42) rolling along the rails (41), lift doors (2) opened and closed by connection with rollers (42) and the lift door anti-falling device (6) for preventing the lift doors (2) from falling. The lift door anti-falling device (6) has a side limiting portion (611) set between the rollers (42) and the flat plate portion (31) at least in closed state of the lift doors (2), thus avoiding the rollers (42) from shaking sidewards. |
