ABSTRACT:
A viscous heater includes a heat generating chamber 10 of a sealed structure. The viscous heater is further provided with a storage chamber SR, which is in communication with the heat generating chamber 10 at its central part, via a recovery hole 3c, a feed groove 3f and a feed hole 3e formed in a rear plate 3 and a rear housing 4. The storage chamber SR can store an amount of the viscous fluid, which exceeds the volume of a heat generating gap between an inner surface of the heat generating chamber and an outer surface of a rotor 16. The speed of degradation of the viscous fluid is slowed, while eliminating the necessity of a strict administration of a charged amount of the viscous fluid.
