A door engagement device for an elevator according to the present invention is configured in such a manner that biasing-force applying/changing means applies a turning preventing force for preventing turning of a lever main body and changes a direction of a biasing force to a direction of an anti-turning preventing force to the lever main body by action of turning guiding means with movement of a car door. Accordingly, an engagement-mechanism driving device can be driven with a reduced space at low cost.
