Abstract: An improved curtain rolling buffer apparatus mainly includes a rolling means mounted to a left end of the track to allow the curtain hanging below the track to be extended by pulling once and retracted by pulling another time. A buffer means is located on the right end of the track and has a bushing housing a spring. When to extend or retract the curtain, the spring is turned clockwise and extended outwards, and runs idle outside an axle, and the elastic force of the spring is smaller than the pressure of lube oil so that the curtain is easier to be extended. On the contrary, when the spring is turned counterclockwise, it is tightened and drives the bushing to rotate together.
