摘要

A friction damper (1) includes: a base body (2); a support (4) secured to an elongated member (35) of the base body (2) and having a through hole (3); a rod (7) which extends in such a manner as to pass through the through hole (3) of the support (4) and is movable in an axial direction (X) with respect to the support (4); a friction member (9) which has a hollow cylindrical portion (8) interposed between the support (4) and a main body portion (85) of the rod (7) in the through hole (3) of the support (4), and which is fixed immovably with respect to the relative movement of the rod (7) in the axial direction (X) with respect to the base body (2); and a tightening means (12) provided for the support (4) so as to tighten the hollow cylindrical portion (8) of the friction member (9) onto the main body portion (85) of the rod (7).
