The present invention relates to a double delta structure of a surgical robot, and to a double delta structure of a surgical robot, which provides a link coupling structure for the double delta structure so as to be resistant against distortion or external force. To this end, disclosed is the double delta structure of a surgical robot, the structure comprising: a first link part link-coupled so as to pitch and yaw around a reference axis in a first direction; a second link part link-coupled so as to pitch and yaw around a reference axis in a second direction; and a third link part link-coupled so as to pitch and yaw around a reference axis in a third direction.
