Abstract

An enclosed-type secondary cell comprises a safety valve (5) made of a metal plate which is deformed with an increase of an internal pressure of the secondary cell, a current interrupting means (6) energized when said safety valve (5) is deformed, an annular gasket (15) for holding an outer peripheral flange portion of the safety valve (5), and a disk (17) serving as a support for detaching a welded portion of a lead plate (17) and a safety valve convex portion (9) when the safety valve (5) is deformed. The annular gasket (15) includes a stepped portion (15e) within a bead-treatment area (21), and the disk (17) is fixed at its outer peripheral portion to the stepped portion (15e) of the annular gasket (15). This enclosed-type secondary cell has the current interrupting means which is energized when the safety valve (4) is deformed with an increase of the internal pressure within the enclosed-type secondary cell. Accordingly, the vacant space of the enclosed-type secondary cell is effectively utilized, and without decreasing a secondary cell capacity, the enclosed-type secondary cell is very strong against shock caused when it is dropped.
