PURPOSE:To prevent degradation of storage capability or leakage resistance capability even if a cylindrical, Mn dry battery is subjected to any shock and also simplify the manufacture process of the cylindrical Mn dry battery by absorbing its shock by means of a sealing gasket made of elastomer having the specific anti-elasticity rate more than its specific value if the cylindrically Mn dry battery is subjected to any shock. CONSTITUTION:A positive pole depolarizing mix 5 is filled in a cylindrical zinc can 2 via a separator 3, and a carbon rod 6 is inserted into the positive pole depolarizing mix 5. A ring sealing gasket 7 is engagingly fitted to the opening part of the zinc can 2 fitting to the carbon rod 6, and a positive polarity terminal plate 9 is fitted on top of the carbon rod 6. The opening part of the zinc can 2 is caulked and sealed, and a cylindrical Mn dry battery 1 is constituted. The material of the sealing gasket 7 is made of an elastomer having its anti-elasticity rate of 40% or more, the shape of which is vertically symmetrical. |
