<p><P>PROBLEM TO BE SOLVED: To hold an electrode winding group stable against a battery container. <P>SOLUTION: A sealing body 22 is abutted on a positive electrode current collecting component 5, a load F1 in a shaft direction is applied to a shaft core 7, and while holding the load, the sealing body 22 is fixed. As for the positive electrode current collecting component 5, in an intermediate annular plate 53, elastic deformation in the shaft direction is formed, and an elastic supporting force F2 in the shaft direction against the shaft core 7 is generated. The electrode winding group 8 is elastically supported in the shaft direction, displacement in the shaft direction is restricted, and the outer force such as impact power is absorbed by the positive electrode current collecting component 5. By the load F1, elastic deformation in a compression direction is also formed in an insulated ring 31, and the elastic supporting force F3 accompanying this elastic deformation is generated. By this, relative rotation of the positive electrode current collecting component 5 and the sealing body 22 is suppressed. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
