Abstract
A supercharger includes a centrifugal compressor having an impeller, a rotational shaft coupled to the impeller, a motor having a stator and a rotor housed in a casing, and a journal air bearing supporting the rotational shaft. The journal air bearing includes a hollow cylindrical member having an inner space therein and a heat transfer member fitted in the inner space. The heat transfer member is made of a material which is less rigid and has a greater coefficient of thermal conductivity than the hollow cylindrical member. The impeller radiates heat transferred through the heat transfer member into ambient air.
