Claim Text:
1. A friction damper comprising: a base body adapted to be capable of being attached to one of a pair of members which are displaced relative to each other; at least first and second supports secured to said base body and having a through hole, respectively; a rod which extends through the through hole of said at least first and second supports, is movable in an axial direction with respect to said at least first and second supports, and is adapted to be capable of being attached to another one of the pair of members; and a friction member which has a hollow cylindrical portion interposed between one of said at least first and second supports and said rod in the through hole of the one of said at least first and second supports and a collar formed integrally with said hollow cylindrical portion, and is fixed immovably with respect to the relative movement of the rod in the axial direction with respect to said base body through said collar, said hollow cylindrical portion of said friction member having a mesh base material disposed on a radially outer peripheral surface side thereof and a synthetic resin-made sliding layer filling meshes of said mesh base material and formed on one surface of said mesh base material, said sliding layer being disposed on a radially inner peripheral surface side of said hollow cylindrical portion so as to be brought into contact with said rod slidably in the axial direction, and said collar being clamped between and by said at least first and second supports without clearances between the first support and the collar, and between the second support and the collar in the axial direction so as to fix said friction member immovably with respect to the relative movement of said rod in the axial direction with respect to said base body.
