PROBLEM TO BE SOLVED: To prevent electrodes from coming into contact with each other to be damaged even when they are subjected to an excessive external force by providing the electrodes for giving an electric field to a throttling path and in the throttling path in the direction in which a damper body and a piston are subjected to vibration of a structure to be moved relatively. SOLUTION: A throttling path 25 in which an electroviscous fluid 58 is throttled to be circulated, is formed between the inner surface of a damper 26 and the side surface of a piston 54. In the damper 26, when a voltage is applied between an electrode 28 provided on the side surface of the piston 54 and an electrode 29 provided on the inner surface of the damper 26, which are provided so as to put the throttling path 25 between themselves, an electric field crossing the flow of the electroviscous fluid 58 passing through in the throttling path 25 at right angles, is formed to increase the viscosity of the electroviscous fluid 58 sandwiched between both the electrodes 28, 29. Thus, the viscosity of the electroviscous fluid 58 passing through the throttling path 25 is controlled, and as a result, the damping coefficient of the damper 26 can be adjusted. |
