Zusammenfassung:	A friction damper comprising: an inner member (126) extending like a shaft; a tubular outer member (127) disposed coaxially with said inner member and on an outer side of said inner member; a frictionally engaging means (129) provided in an annular space on a radially outward side of said inner member and on a radially inward side of said outer member; a resilient means (130) provided in the annular space; an urging-force varying means (161, 162) provided in the annular space, wherein said frictionally engaging means (129) has a first portion which rotates integrally with said inner member (126) and a second portion which rotates integrally with said outer member (127) and is provided in such a manner as to be capable of coming into contact with said first portion in the axial direction, wherein said resilient means (130) is arranged to urge said first portion and said second portion in a direction in which said first portion and said second portion are brought into contact with each other and are pressed against each other, and wherein said urging-force varying means (161, 162) is arranged to make variable an urging force of said resilient means (130) in correspondence with a relative rotational displacement of said inner member and said outer member.
