PROBLEM TO BE SOLVED: To establish complete closing of a landing door by positively moving the landing door to a predetermined door closing position at its door closing time without reinforcing force of a closer. SOLUTION: The door device for an elevator is equipped with the landing door 10 and a car door 27. At a door opening time, immediately after the car door 27 having a driving force moves from a door closed position in the door opening direction, the car door 27 engages with the landing door 10 via an engagement mechanism 28 and both the doors move in the door opening direction. At a door closing time, the engagement is released immediately before the car door 27 and the landing door 10, in an engaged state, move integrally in the door closing direction and reach the door closing position, and transfer of the driving force from the car door 27 to the landing door 10 is intercepted. The device is also provided with a toggle spring mechanism 14 for elastically pressing the landing door 10 in the door closing direction at a door closing time by engaging with the landing door 10 immediately before the car door 27 and the landing door 10 get close to the door closing position and the engagement of the car door 27 and the landing door 10 is released.
