A damping buffer apparatus for a flip-down ceiling screen including a case 1 and a lid 2 pivotally coupled with one lateral end 100 of the case 1 for holding a screen 20. The lateral end 100 has two sides forming a first action side A and a corresponding second actions side B. The first action aside A has a speed reducing mechanism 11, 111 to reduce the flipping speed of the lid 2 via a damper C and a reducing gear set T and provide a buffer effect when the lid 2 is driven by a first elastic element S1 and unfolds. The second action side B has a second elastic element S2 compressed by the flipping lid 2 at the initial unfolding stage during the buffering process, and expanded at a later unfolding stage of the lid 2 to provide a returning elastic force to move and anchor the lid 2 in a desired position. The impact and vibration resulting from fast flipping of the lid 2 is thus minimised and may be prevented.
