Have. The above configuration is the same as that of the conventional storage battery shown in FIG. According to the present invention, as clearly shown in FIG. 2, the cap-shaped rubber valve 4 to be tightly fitted to the cylinder 3 is composed of a circular cap-shaped rubber valve main body 4a and an engaging projection 4b protruding on the outer periphery thereof. On the other hand, the battery case lid 1 has a small insertion space 5 outside the cylinder 3 and a projection 6 for holding provided with a holding portion 6a. In the illustrated example, the engagement projection 4b of the rubber valve 4 is formed in an annular flange shape at the lower end of the cap-shaped valve body 4a. Reference numeral 6 denotes a pair of cylinders 3 arranged on the left and right sides in the radial direction of the cylinder 3, and the shape thereof is a hook-shaped L-shaped projection.
The holding portions 6a, 6b are directed toward the peripheral side surface of the cylinder 3, and are horizontally projected with insertion spaces 5, 5 therebetween.
