PURPOSE: A vibration absorbing device for a drainage is provided to effectively absorb noise generated when fluids pass through the drainage by absorbing vibration before vibration is applied to the drainage. CONSTITUTION: The drainage(1) is installed in a structure, such as a building, so as to discharge fluids to an exterior. A vibration absorbing tube(2) is installed in the drainage(1). A vibration shielding space section(3) is formed between the drainage(1) and the vibration absorbing tube(2). The vibration absorbing tube(2) is installed in a vibration generating area in the drainage(1). The vibration absorbing tube(2) includes a free end(20), which is closely adjacent to an inner wall of the drainage(1). The free end(20) guides fluids from an inner wall of the vibration absorbing tube(2) to an inner wall of the drainage(1).
