PURPOSE:To prevent any generation of static electricity without decreasing the strength of a case for a storage battery by preparing the inner layers of an electrolyzer and a lid from a synthetic resin containing an antistatic agent, and integrating the said inner layers with the outer layers, which are prepared from a synthetic resin containing no antistatic agents. CONSTITUTION:An electrolyzer 1 and a lid are formed by molding an inner layer 1' and an outer layer 1'' into a unified body by means of a metal mold 5. The inner layer 1' is formed of a synthetic resin containing an antistatic agent, the layer 1' formed is installed in a metal mold 5, and the outer layer 1'' is integrated with the layer 1' so that the upper and the lower ends of the layer 1' are covered with the layer 1''. Here, the layer 1'' is prepared from a synthetic resin containing no antistatic agents. |
