Abstract
A device using an electrorheological fluid filled in a fluid enclosing space comprises passages or fins for cooling the electrorheological fluid disposed around the fluid enclosing space and is useful for a vibration damper, a clutch, an engine mount, a shock absorber and the like. The power consumption can be maintained at a sufficiently low level and thermal runaway of electric current can effectively be prevented.
