ABSTRACT:
A viscous fluid type heating apparatus capable of achieving both reliable prevention of deterioration in the heat-generating performance of a viscous fluid and reliable prevention of leakage of the viscous fluid from the apparatus, and having a heat generating chamber provided with a first and a second storing region for storing a silicone oil to avoid an application of a shearing action from a rotor element to the viscous fluid and a heat generating gap. The silicone oil is held in the heat generating chamber so that it is able to flow between the heat generating gap and the first storing region which is directly affected by a thermal condition in the heat generating gap. The second storing region is substantially separated from the first storing region and is not directly affected by the thermal condition in the heat generating gap. The flow of the silicone oil between the first and second storing regions is adjustable by a movable element.
