Abstract
In a heat generator for a vehicle according to the present invention, an operation chamber defined in the heat generator is composed of a heat generation area ( ) which receives therein a rotor, a storage area ( ) which contains viscous fluid, and a boundary opening ( ) of a relatively large surface area, which connects the two areas. The boundary opening is provided with a pair of transfer openings ( A, B) in a point-symmetric arrangement with respect to the rotation axis C of the rotor. Guide portions ( A, B), each corresponding to each of the openings, are provided in the storage area. With this structure, since at least one of the transfer openings and the guide portion corresponding thereto are located below the surface level L of the viscous fluid regardless of the attachment angle of the heat generator, the exchange and circulation of the viscous fluid can be carried out between the heat generation area and the storage area, in accordance with the rotation of the rotor.
