Abstract

PURPOSE:To prevent damage to members such as plates, etc., and facillitate a change of design by forming both fixed plates and movable plates unmovable in the direction of rotation of the movable shaft and movable in the direction of their thickness. CONSTITUTION:When an external force is applied to a movable shaft 2 as torque, movable plates 6, 6... are rotated in a viscous fluid A, a viscous shear resistance force is generated due to the viscous fluid A between the movable plates and stationary fixed plates 7, 7..., and the resistance force acts as a resistance against the external force to allow the device to effectively function as a damper. At this time, the viscous fluid A has a property of flowing to a place of greater viscous shear resistance force, so that the viscous fluid A flows into a com paratively narrowed clearance of increased viscous shear resistance regardless of some differences in spacing of clearance between the movable plates 6, 6... and fixed plates 7, 7..., and the movable plates 6, 6... and fixed plates 7, 7... having respectively certain degrees of freedom fluctuate. And, the clearance of the entire plate equally divides the plate-free length H, so that troubles such as damage to the members due to locally excessive resistance do not occur.
