<p>A high-speed rotating shaft (10) for superchargers which is rotatably held by two radial bearings (12a) and (12b) apart from each other at a certain distance (L), directly connects a turbine impeller fixed to one end thereof to a compressor impeller fixed to the other end, and transmits the rotating driving power of the turbine impeller to the compressor impeller. The rotating shaft has, between the bearings, a thin shaft part (14) having a smaller diameter than the bearing parts. This thin shaft part (14) is offset toward the compressor side.</p> |
