Abstract
A viscous coupling capable of preventing decrease in torque obtained by the shear force. The viscous coupling includes relatively rotatable first, second, and third rotating members forming an operation chamber in which a viscous fluid is to be confined; a dividing member placed inside the operation chamber for dividing the operation chamber into a first chamber formed by the dividing member and the first and third rotating members, and a second chamber formed by the dividing member and the second and third rotating members; and a pump for controlling flow of the viscous fluid between the first and second chambers.
