To provide a pushing device for a sliding door permitting to open and close the door with a small force required.
This pushing device for the sliding door comprises a lever member installed in a rotatable manner about an axis of rotation at a center of a plane on the top face of the sliding door; a biasing means for positioning the lever member to its turning direction so as to locate an acting point of force of the lever member to a first top frame side; a direction averting member installed to the first top frame side which acts to the acting point of force immediately before the sliding door is closed and pushes the door backward by giving a force against an exerting force by the exerting means as the sliding door is being closed; and a pushing member installed to a second top frame side and being subjected to a force at its acting point when the lever member is pushed backward with a length of a first arm extended perpendicularly in a direction of a force acting to the acting point of force of the lever member, which is longer than the length of the second arm extended perpendicularly to the direction of a force acting to its acting point from the axis of rotation.
