PROBLEM TO BE SOLVED: To provide an inexpensive and compact friction damper that generates friction power of different magnitudes. SOLUTION: The friction damper is provided between two members which relatively move in a predetermined direction to attenuate the vibration with respect to the relative movement between the two members by the friction power. The friction damper has: a first pressure-welded plate integrally provided in one of the two members; a second pressure-welded plate integrally provided in the other one of the two members; and a friction plate which is pressure-welded on both of the first pressure-welded plate and the second pressure-welded plate by the predetermined pressure-welded power between the first pressure-welded plate and the second pressure-welded plate. The first friction coefficient on the first friction face pressure-welded on the first pressure-welded plate in the friction plate is larger than the second friction coefficient on the second friction face pressure-welded on the second pressure-welded plate in the friction plate. If the amplitude of the vibration is within a predetermined value, the friction plate does not slide on the first friction face but slides on the second friction face. If the amplitude of the vibration exceeds the predetermined value, the friction plate slides on the first friction face. COPYRIGHT: (C)2012,JPO&INPIT |
