PROBLEM TO BE SOLVED: To provide the terminal structure of a storage battery, which can certainly prevent electrolyte from leaking out without an increase in a parts count. SOLUTION: The terminal structure of the storage battery includes a lid 2 for closing a case, the lid 2 being made of a synthetic resin material; and a bushing 5 whose cross-section is in an annular shape and which has spiral flanges or a plurality of annular flanges 5A to 5E formed along the vertical direction thereof. The lid 2 is integrated into the bushing 5 by means of insert molding, with the flanges 5A to 5E embedded into the lid 2. The bushing 5 has projection section and concave section 5M in the area where the bushing 5 is embedded into the synthetic resin material. The projection section is formed so as to project into the synthetic resin material in a direction crossing the vertical or horizontal direction. The concave section 5M is formed in a direction crossing the vertical or horizontal direction in which the synthetic resin material extends into the bushing 5. COPYRIGHT: (C)2009,JPO&INPIT
