Document Type and Number:
Japanese Patent JPH0613060
Kind Code:
A
Abstract:

PURPOSE: To suppress the outflow of an electrolyte from a bursting through hole at opening and suppress the inflow of silicon oil into an electrode plate group receiving space at pressure reduction.

CONSTITUTION: An electrode plate group 8 is received in a battery jar 4 formed by bonding the circumferences of two synthetic resin bodies 1, 2 to each other by thermal welding. One synthetic resin body 1 has a bursting through hole 9 formed thereon. On the outside of the bursting through hole 9, a part bonding part for partially bonding the two synthetic resin bodies 1, 2 to each other is formed.
