PURPOSE: A non-power hydraulic elevator door apparatus is provided to open and close an elevator and an elevator door with one elevator power because the elevator and the elevator door are respectively supported by a fan belt and a wire rope on a closed loop. CONSTITUTION: A non-power hydraulic elevator door apparatus comprises a variable coupling unit and a non-power coupling unit(100A). The variable coupling unit comprises a vertical heating plate and a cam plate. The cam plate drives separation operation of a heating plate lever. The non-power coupling unit pushes a first push roller(125) to release locking of an elevator door(100) with non-power when matching the vertical heating plate with horizontal position. The lower end of a cam plate lever is fixed in one side of the cam plate and a switch part is installed in an elevator frame in order to operate acceleration/deceleration by communicating with a switch shaft which is a rotary shaft of the cam plate lever when the door opens and closes according to moving the position of the cam plate.
