Abstract

A sealing gasket of a cell comprises a circumferential marginal portion constricted between a metal casing and a terminal plate, a center collar through which a collector metal rod penetrates, and an intermediate portion integrally molded with the marginal portion and the center collar and having a thin wall portion tearable by a stretching force applied thereto. The center collar of the gasket is normally separated from the terminal plate but is movable toward the terminal plate by sliding on the collector metal rod in the event that the internal gas pressure within the cell is abnormally developed, whereby the thin wall portion of the gasket is stretched and torn to release the gas.
