Abstract
A viscous fluid type heat generator having a sealed heat generating chamber in which heat generation in the viscous fluid is carried out in response to the rotation of a rotor element received in the heat generating chamber and applying a shearing action to the viscous fluid, the sealed heat generating chamber having front and rear heat generating chamber portions on both sides of the rotor element and a large annular gap extending between the front and rear heat generating chamber portions and surrounding the rotor element to provide a fluid communication between the front and rear heat generating chamber portions in order to prevent the viscous fluid in the first and second heat generating portions from being unequally degraded.
