Abstract
An object of the invention is to provide a lid for storage battery comprising a terminal having a rectangular parallelepiped shape and a cavity portion, and a nut having a rectangular parallelepiped shape and being inserted into the cavity portion. The terminal has a first through-hole extending from an upper surface toward a lower surface of the terminal and a second through-hole extending from a front surface toward a rear plate portion of the terminal. The nut has a first screw hole extending from an upper surface toward a lower surface of the nut, and a second screw hole extending from a front surface toward a back surface of the nut, the first and second screw holes communicating with the first and second through-holes of the terminal, respectively. A direction in which the first screw hole extends does not intersect with a direction in which the second screw hole extends.
