摩擦ダンパー

Japanese Patent JP7132867

B2

To provide a friction damper that can generate large friction force even when a displacement is large and cope with from a low displacement to a high displacement with a compact shape.SOLUTION: A friction damper 1 includes first and second support materials 2, 3, and first and second friction materials 4, 5 that are disposed adjacently in a direction in which the first and second friction materials are applied with compressive force by clamping of the support materials 2, 3 and are pressed to each other by the compressive force. The friction damper includes an inner contact part 10 where the first and second friction materials 4, 5 abut to each other, first and second outer contact parts 11, 12 where the first and second friction materials 4, 5 and the first and second supporting materials 2, 3 abut to each other, and resistance raising parts 8, 8 that are formed on the second friction material 5 and abut to the first friction material 4 to raise friction resistance when the first and second friction materials 4, 5 move relatively to each other. When the first friction material 4 abuts to the resistance raising part 8 and a load associated with the relative movement exceeds static friction force of the first outer contact part 11, the second friction material 5 moves relatively to the second support material 3.SELECTED DRAWING: Figure 1
