Abstract
A heat generator comprises a partitioning wall,in opposed relation to a rotor in a heat generating area, in which the partitioning wall is formed with a supply groove,for introducing the viscous fluid to the outer peripheral area of the heat generating area from a storage area, and a recovery groove,for leading out the viscous fluid to the storage area from the outer peripheral area of the heat generating area. The shape, position and the mounting angle of the supply groove,and the recovery groove,are designed to set the outflow ratio &agr; to not more than 0.92. The outflow ratio &agr; is defined as the ratio (&agr;=Qout,/Qin) of the amount Qout,of the viscous fluid flowing out from the heat generating area due to the forcible transfer function of the recovery groove,to the total amount Qin of the viscous fluid flowing from the storage area into the heat generating area.
