There is provided a storage battery, including: a container having at least one cell chamber; a lid body (2) made of synthetic resin for covering a top opening of the container, the lid body having on a top surface a recessed portion that is recessed downward, the lid body having positive and negative electrode terminals disposed close to one side of the lid body and respectively at both end portions of said one side in a longitudinal direction, wherein the positive and negative electrode terminals (4) respectively have lower portions embedded in the lid body and upper portions projecting from the lid body; and an auxiliary lid (9) for closing the recessed portion. Conventional production of the storage battery has problems, for example, in that: when embedding a portion of a terminal to a lid body by insert molding, difference in shrinkage is caused between a surface in which a terminal body is embedded and a surface on which the terminal body is exposed, which results in difficulty in fitting the lid body to the container. The present invention is intended to solve this problem, for example, by providing the lid body of the storage battery with projections (6T, 7T), each at a location at which the upper portion of each of the terminals projects, at a location proximate to the location at which the upper portion of each of the terminals 4 projects, or at each of these locations. |
