MANGANESE DRY BATTERY

PROBLEM TO BE SOLVED: To provide a highly safe manganese dry battery capable of surely evacuating a generated gas and preventing explosion when generating a gas within the battery due to reverse connection or short circuit and the pressure inside the battery becoming abnormally high. SOLUTION: In this manganese dry battery wherein the battery is sealed with a sealing element 3 having an inner cylinder 13 holding a carbon rod, an outer cylinder closely contacted to the opening inner wall of a zinc can and a coupling part for coupling both cylinders and the outer cylinder of the sealing element 3 is pressed and closed with the outer peripheral rim of a positive electrode terminal plate having an exhaust hole and the opening of the zinc can, a groove 13a is disposed on the top of the inner cylinder 13 of the sealing element 3 for communicating the outside with the inside of the inner cylinder 13. Further, a groove 13b vertically passing through is disposed on the surface to press the carbon rod of the inner surface of the inner cylinder 13 of the sealing element 3.
