Abstract: This light illumination unit comprises: a heat sink that has a plate-shaped heat sink body and fins protruding from a first main surface of the heat sink body; an electronic substrate that is laminated on a second main surface of the heat sink body on the reverse side thereof from the first main surface; and a light illumination element that is mounted on a first surface of the electronic substrate on the side thereof where the heat sink is provided. As a result of said configuration, it is possible to save space as well as power.

Abstract: In a vehicle air conditioning apparatus in which a plurality of air mixing dampers that are driven independently of each other have a drive shaft having a double-shaft structure. A hollow drive shaft of one damper is penetrated by a solid drive shaft of another damper. A first shaft-center immobilizing mechanism that secures a shaft center of the hollow drive shaft is provided between a side surface of the unit casing, to which the drive shaft having the double-shaft structure is supported in a freely rotatable manner. And a gear provided at a shaft end of the hollow drive shaft.
