<P>PROBLEM TO BE SOLVED: To solve the following problems: a rotary shaft inserted in a casing having an opening-closing door is conventionally cantilevered, consequently a load, that is, the condition of supporting the shaft is distorted due to the pressure differential between upper and lower parts to impair a smooth operation and cause sometimes damage to a component. <P>SOLUTION: The structure for bearing a rotary shaft includes a casing having an opening-closing door on the side. The rotary shaft is inserted in the casing, and provided with a rotor. A receiving-hole is made in the free end-face constituting the side of the opening-closing door for the rotary shaft. A support shaft, which is provided within the opening-closing door and has a truncated-conical end, is fit into the receiving hole. The bearing structure includes further an energizing means, which gives an energizing force in the axial direction of the rotary shaft. <P>COPYRIGHT: (C)2008,JPO&INPIT |
