During the process movement, the air diffusion paper 2 is displaced from the normal insertion point (referred to as part A), and a part of it is displaced to part B, and when a battery is manufactured in this state, the sealing plate electrolyte However, there was a problem in that the liquid easily leaked from the vicinity of the B section through the air diffusion paper and into the positive electrode case air hole 9. (See FIGS. 3 and 4) Means for Solving the Problems In order to solve the above problems, in the present invention, a positive electrode case having a stepped portion on the outer circumference of the bottom has a convex portion on the inside of the bottom, It has an air diffusion paper having a hole that matches the shape formed by the intersection of the convex part and the inner flat part of the bottom, and this air diffusion paper is inserted into the convex part and installed inside the bottom of the positive electrode case. It is.
作用
本発明の手段によシ、空気拡散紙が正極ケース底部での
正規設置場所からズレることか防止できる。Function: By means of the present invention, it is possible to prevent the air diffusion paper from shifting from its normal installation location at the bottom of the positive electrode case.
