    • A sealed battery includes a can for receiving an electric generator, a shape-variable plate crimped on an opening of the can, a gasket disposed between the can and the shape-variable plate, a fixing plate disposed under the shape-variable plate, an insulating member disposed between the shape-variable plate and the fixing plate, and a projection extending from the fixing plate and welded on the shape-variable plate. The projection is provided with a mechanically weak portion which is designed to be broken at an internal pressure lower than that for separating a welding portion of the projection and the shape-variable plate.
    • 密封电池包括用于接收发电机的罐,卷绕在罐的开口上的形状可变的板,设置在罐和形状可变板之间的垫圈,设置在形状可变板下方的固定板, 设置在形状可变板和固定板之间的绝缘构件和从固定板延伸并焊接在形状可变板上的突起。 突起设置有机械弱部,该机械弱部被设计成在比用于分离突起和形状可变板的焊接部的内压低的内部压力下断裂。
