PROBLEM TO BE SOLVED: To provide a friction damper which is light is weight and simple in constitution, exhibits an excellent attenuation effect even at a small stroke, and hardly increases a spring constant at a machine side. ! SOLUTION: A friction damper which attenuates vibration between constituent members comprises a shaft member 2 arranged at one constituent member, and a housing member 3 which is arranged at the other constituent member, and has a hole into which the shaft member 2 is fit. A slide member 4 in which an elastic material and a cloth material are integrated to each other, and a spiral salient part or a groove part 6 is arranged at an external peripheral face is arranged at one of an external peripheral face of the shaft member 2 and an internal peripheral face of the hole of the housing member 3, and at the other face, there is formed the spiral groove part 6 or the salient part which is screwed to the salient part of the slide member 4 or the groove part 6. When the shaft member 2 and |
