Viscous shear type rotary damper

摘要

Problem to be solved: to provide a viscous shear type rotary damper capable of obtaining a good damping force.Viscous shearing type rotary damper 1A first member 3 having a first tapered surface 100 andThe first tapered surface 100 has a second tapered surface 200 opposed to the first tapered surfaceThe second member 4 which is relatively rotatable relative to the first member 3 without changing a predetermined distanceA viscous material filled between the first tapered surface 100 and the second tapered surfaceA retracting mechanism for moving the first member 3 and the second member 4 relatively and capable of adjusting the clearance between the first tapered surface 100 and the second tapered surface.Diagram
