A vibration absorber (7) comprises a hollow outside long-sized body (21) in the form of a cylindrical member, a hollow inside long-sized body (22) also in the form of a cylindrical member, a viscous body (26) disposed in a cylindrical clearance (25) defined between the inner surface (23) and outer surface (24) of these long-sized bodies (21, 22) so that the viscous body is in contact with the inner and outer surfaces (23, 24) of these long-sized bodies (21, 22), rectangular attaching plate members (31, 32) respectively fixed to the other end (29) of the long-sized body (21), which has one end (28) on the side of an open end (27), on the closed side in the axial direction (X), and to one end (30) of the long-sized body (22) on the closed side, and a holding means (33) for holding the clearance (25) between the inner surface (23) of the long-sized body (21) at one end (28) of the long- sized body (21) and the outer surface (24) of the long-sized body (22).
