<p><P>PROBLEM TO BE SOLVED: To provide a flyer bow which contributes to energy-saving by reducing air resistance when the flyer bow is rotated. <P>SOLUTION: The flyer bow is provided with a planar shape which is narrower in the width W<SB>1</SB>of the middle part 10b in the longitudinal direction as compared with the width W<SB>0</SB>of the end parts 10a in the longitudinal direction. The intermediate parts between the middle part in the longitudinal direction and the end parts in the longitudinal direction may be made into the planar shape the width of which is smoothly and gradually increased according as proceeding from the middle part in the longitudinal direction to the end parts in the longitudinal direction. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
