<P>PROBLEM TO BE SOLVED: To reduce friction which is greatly generated since a frame of a contact part is slightly enlarged when a fine movable piece of a tip of a rotor in the frame firstly contacts with the frame as the frame storing each rotor is broken along the way, the fine movable piece is stuck to and separated from the frame having an inclined surface from a side at a high speed and both lateral and longitudinal components of friction are applied to a tip of the fine movable piece. <P>SOLUTION: A roller pinch capable of moving in and out which is pressed by a spring from a rear side over the roller is arranged at the tip of each rotor where the frame is broken and the tip contacts with the frame again. The speed of the roller is the same as the fastest part of each rotor. As each fine movable piece contacts with each corresponding roller to make a small pit and contacts with a surface behind the roller pinch from above, the lateral friction is eliminated and the wear of each fine movable piece is reduced. <P>COPYRIGHT: (C)2010,JPO&INPIT |
