<P>PROBLEM TO BE SOLVED: To solve the problems that a thin gasket produced by injection molding easily deforms because an outer cylinder part 7 of the gasket enters a groove 11 formed between the outer cylinder part and an inner cylinder part during transportation and battery assembly and that when gaskets overlaps with each other, a trouble is caused in the production process in a discharge operation, etc., thereby reducing productivity. <P>SOLUTION: In a gasket 5 for a coin-shaped battery comprising an outer cylinder part 7, an inner cylinder part 8 shorter in height than the outer cylinder part 7, and a bottom connecting part 9 for connecting the outer and inner cylinder parts, a thickness A in at least one portion of the upper part in the outer cylinder part 7 is made larger than a width B in a groove 11 formed between the outer cylinder part 7 and the inner cylinder part 8 so as to prevent the gaskets from overlapping with each other during transportation and in a part feeder, thereby increasing productivity in the production process. <P>COPYRIGHT: (C)2012,JPO&INPIT |
