<P>PROBLEM TO BE SOLVED: To obtain a winding core having relatively simple structure capable of clipping and fixing a separator. <P>SOLUTION: The winding core 21 comprises an outer axis 22 on which a positive electrode 6, a negative electrode 7, and a separator 9 are wound, an inner axis 25 to fix the separator 9, and a receptacle axis 26 in which an insertion part 35 is engaged at the tip part 25b of the inner axis 25. The outer axis 22 has a space 23 opened at one end and the inner axis 25 is arranged in the space 23. The inner axis 25 has an inner axis slit 29 opened at the tip. The outer axis 22 has an outer axis slit 27 opposed to the inner axis slit 29. Separators 9, 9 piled in two are introduced in the inner axis slit 29 through the outer axis slit 27 and when the insertion part of the receptacle axis 26 is engaged at the tip part 25b of the inner axis 25, the separator 9 is clipped and fixed by the closed inner slit 29. <P>COPYRIGHT: (C)2007,JPO&INPIT |
