An objective of the present invention is to provide a pushback device for a door allowing a function to be realized while a door is closed. According to the present invention, the pushback device for a door comprises: a transport block formed to be transported by a driving part; a guide unit coupled to the transport block; a slide arm wherein one end thereof is connected to the guide unit to be slid and moved, and the other end thereof is fixed on a door; a first spring installed between the guide unit and the slide arm, and installed to apply an elastic force to the slide arm; and a movement limiting part blocking the slide arm from being moved with respect to the guide unit when the door is opened, and formed to allow the slide arm to be moved with respect to the guide unit if an external force is applied in a direction of opening the door by canceling the blocking state when the door is closed.
