An automobile heating apparatus according to this invention includes: a water pump for circulating the cooling water for an automobile water-cooling engine; a radiator for heating the air to be introduced into the automobile room by utilizing the cooling water delivered by the water pump as a heat source; and a hot water circuit for circulating the cooling water in the automobile water-cooling engine, the water pump and the radiator; wherein a heat generator is disposed in the hot water circuit at an upstream portion with respect to the radiator, and the heat generator includes; a heat generating chamber having a labyrinth groove and containing viscous fluid therein; a housing disposed adjacent to the heat generating chamber and having a heat receiving path constituting part of the hot water circuit; a shaft held rotatably in the housing and receiving the rotary torque of the automobile water-cooling engine by way of clutch means; and a rotor fixed on the shaft at an end thereof and having a labyrinth groove disposed in the heat generating chamber. The automobile heating apparatus is down-sized and light-weighted by only providing this simple and compact heat generator in the hot water circuit thereof, because there is no further need for connecting the exhaust pipe and the hot water circuit for heating by way of the heat exchanger of large size as in a prior art automobile heating apparatus.
