PROBLEM TO BE SOLVED: To reduce the height of a damper body and to reduce its fitting space by using a resin film of the prescribed thickness to a vessel body, and unevenly forming outer circumferential wall in a bellows manner. SOLUTION: In a damper 10, the viscous liquid 3 is sealed in a vessel comprising a cup-shaped vessel body 1 and a plate-like lid body 2, the vessel body 1 is formed of a resin film small in expansion and of <=1 mm in thickness, an outer circumferential wall is of uneven bellows shape, enabling the movement of the vessel body 1 caused by the bending deformation in each direction. The material of the resin film is not limited so long as the uneven forming is realized, and includes a film formed of polyethylene resin, palypropylene risin, etc., or laminated films thereof. The depth of the vessel body 1 is preferably <=1/2 of the outside diameter of the damper in order to increase the relative displacement per unit thickness of the viscous fluid. A stirring part can be dispensed with, the height of the damper can be reduced, and the fitting space can be reduced. |
