Abstract
A heating device for a vehicle is provided with a radiation-heat generating unit for generating radiation heat, a first light-distributing unit for converting irradiation directions of the radiation heat into a substantial single irradiation direction, and a second light-distributing unit for distributing the radiation heat to at least one heating object in a passenger compartment of the vehicle. The second light-distributing unit slantways intersects the radiation heat which has the substantial single irradiation direction converted by the first light-distributing unit.
