Claims

[Scope of utility model registration request]

(1) A sealed electrolytic capacitor characterized in that a narrow groove made of a spiral or involute continuous curve is provided on the bottom of a case made of metal or synthetic resin to form a thin wall part.

(2) Utility model registration claim (1) characterized in that the narrow groove formed of a spiral or involute continuous curve is provided symmetrically on the outside or inside of the bottom surface of the case, or both. sealed electrolytic capacitor.

(3) The spiral or involute type continuous curved thin groove has its starting point at the center of the bottom surface of the case, and the thickness of the thin part is the thinnest at the starting point and toward the outside. The sealed electrolytic capacitor according to claim (1) of the utility model registration, characterized in that the capacitor is formed so that the thickness thereof gradually increases.

(4) A utility model characterized in that the narrow groove formed of a spiral or involute continuous curve has a starting point at the center of the bottom surface of the case, and a small groove perpendicular to the starting point. A sealed electrolytic capacitor according to claim (1).
