Abstract: Disclosed is a shock absorption device including a dual fall prevention band connected to a safety rope connected to a safety harness that a worker wears. The shock absorption device including the dual fall prevention band includes a dual fall prevention band and a shock absorption band. The dual fall prevention band is shaped like a closed loop by coupling opposite ends thereof through a first seam, and the first ring, the second ring, a third ring, and a fourth ring are formed by coupling parts of the dual fall prevention band that face each other at a first position to each other through a second seam, and coupling parts of the dual fall prevention band that face each other at a second position to each other through a third seam.
