PURPOSE:To apply to a pair of synthetic resin bodies a force exerted in the direction in which the bodies attract each other and apply pressure to a group of pole plates without using a case for applying pressure nor providing structure for applying pressure on the side of battery-used equipment by inserting insulating resin bodies into respective through holes each of which is bored through the group of pole plates in the direction in which the plates are stacked, and joining to the insulating resin bodies a pair of respective synthetic resin bodies constituting a battery jar. CONSTITUTION:A positive electrode plate 3 and a negative electrode plate 4 are joined to respective synthetic resin bodies 1 and 2. While the holes of the members 3b1 and 3b2, 4b1 and 4b2, 5a1 and 5a2 are adjusted to each other, through holes 6a, 6b each of which is bored through the group of pole plates are formed. Insulating resin bodies 7a, 7b of acid resistance and water repellency such as a polypropylene resin or a fluororesin, etc., are inserted into the respective through holes 6a, 6b. Both end portions of each insulating resin body 7a,7b which extend in the direction in which the pole plates are stacked are joined to the synthetic resin bodies 1, 2 so that a force exerted in the direction in which the synthetic resin bodies 1, 2 attract each other is generated. |
