<P>PROBLEM TO BE SOLVED: To eliminate gaps between rotors, and between a rotor and a rotor frame. <P>SOLUTION: A space 12 is provided at an inner part of a concave surface of a rotor. A hooking part is provided at an outer side thereof. A partly narrowed leg 5 is provided at an outside thereof. A spring space 11 is provided at a side thereof. A seal plate 10 is provided at outside thereof. The leg 5 is wound in a spiral shape by a compressed spring 8. A seal with hooking leg is provided on the concave surface, and it is preferable if it is on a rotor tip. A section of one rotor without the seal with the hooking leg is kept not to overlap a section of another rotor without the seal with the hooking leg. <P>COPYRIGHT: (C)2009,JPO&INPIT |
