A automatic weight-activated toilet flushing apparatus, includes an automatic bounding device, a lifting/lowering device and a control box, wherein the bounding device is connected under a rear portion of a pad of a toilet bowl and connected to the lifting/lowering device so that when a user sits on the pad, the same is pressed down through a certain distance and the lifting/lowering device is simultaneously moved down, causing a slide block thereof to move downward. Meanwhile, a one-way control member is moved upward and biased by a pressing rod of the control box. When the user stands up, the slide block is moved back upward, making the one-way control member move downward to press down the pressing rod. When the pressing rod moves downward, a control rod of the control box is urged to move upward and open a valve of a water tank so as to discharge the water contained therein.
