PURPOSE:To restrict damages of the battery as well as reduce the actual space capacity and decrease a blasting ability, by furnishing a spacer of a foam polyethylene with a hole for projecting the electrode pole at a connecting shelf to be a collector of the electrode plate set. CONSTITUTION:A spacer 7 consisting of an acid-proof foams polyethylene is placed on a connecting shelf 8 to be a collector of the electrode plate set 5. At the side of the spacer 7, four cuttings 9 are arranged, whose width is a little smaller than that of a connecting body 10 between cells. Therefore, when the spacer 7 is inserted, the cuttings 9 are closely contacted to the connecting body 10 while the size is being expanded, remaining still on the shelf 8. Consequently, the spacer 7 is fastened securely and prevented from moving by a vibration or the like. Furthermore, since the spacer 7 is on the shelf 8, the electrolyte can be kept in the space between the electrode plate set 5 and the connecting shelf 8. Moreover, the spacer 7 is used for controlling the rise of the liquid level when the liquid is poured. The cuttings 9 are also utilized to prevent the blocking of an airing passage 6 between cells. |
