<P>PROBLEM TO BE SOLVED: To provide a rotary shaft holding structure and a motor-driven supercharger including this structure, capable of reducing the shaft length and weight of a rotary shaft. <P>SOLUTION: In this rotary shaft holding structure, the rotary shaft holding structure in the motor-driven supercharger has a shaft 310, a rotor 320 fixed to the shaft 310, and a spacer 330 arranged in both end parts in the axial direction of the rotor 320. Here, a sliding surface rotatably slidable with a floating bearing 340 is formed on an end surface in the axial direction of the spacer 330. The floating bearing 340 is arranged so as to be adjacent to the sliding surface. <P>COPYRIGHT: (C)2008,JPO&INPIT |
