[Effect of device]

 Thus, according to the present invention, a concave valve chamber is formed on the flat top wall surface of the battery case lid so as to correspond to the cell chamber of the battery case and is connected to the negative and positive terminal straps. Since the sub-plate is held by being inserted and held in the terminal holder arranged on the outer surface of the short side wall of the battery case, and the lower end of the sub-plate is used as the coupler connection terminal, it is higher than the conventional storage battery of this type. It is possible to significantly reduce the height, and thus increase the volumetric efficiency, and to connect the coupler of the electric device on the short side of the storage battery, which is easy to connect. In addition, by extending the bulging wall at one end of the battery case lid, it is possible to accommodate the shade, the shade connected to the strap for the anode terminal, and the upper end of the anode terminal plate inside the battery case lid. The recess formed on the back surface of the bulging wall at one end of the base accommodates the shade, the anode terminal strap, the upper end of the short side wall of the battery case, and the top of the anode terminal plate, and these are filled in the recess. By embedding with an adhesive, it is possible to obtain a stable and stable sealed storage battery for a motorcycle or the like.
