Claims

[Scope of utility model registration request]

Rotating bodies are pivotally supported on the left and right sides of a fixed member above a single-swinging door that opens and closes the car entrance, and the door wrapped around these rotating bodies is opened and closed by the rotational drive of one of the rotating bodies. In the elevator door drive device, only the opening/closing stroke of the door is made up of meshing transmission strips such as chains or toothed belts, and the rest of the strips are made of ropes such as wire ropes. What is claimed is: 1. A driving device for an elevator door, characterized in that a rotary body that meshes with the mesh transmission strip is disposed on the door bag side, and a rotary body that supports the rope is disposed on the door stop side.
