Claims

[Scope of utility model registration request]

A recessed chamber is formed in a part of the outer surface of the lid of the battery container, and an exhaust pipe connected to the recessed chamber is protruded from the upper surface of the hole that communicates the cell chamber in the battery case and the recessed chamber formed in the center of the bottom wall of the recessed chamber. In a safety valve device for a sealed storage battery, an elastic cylindrical cap is fitted to the tip of the exhaust pipe, and a cap-shaped lid is fixed to the open surface of the concave chamber, the lid being a top wall. An elastic cap-shaped lid is formed with a circumferential side wall in sliding contact with the inner circumferential side of the concave chamber, and this is slidably fitted on the inner circumferential side of the concave chamber. A locking recess and a locking protrusion provided on the outer surface of the side wall and the inner circumferential surface of the recess are loosely fitted into each other, and furthermore, a cylindrical clearance is formed between the joint surfaces of these two. A safety valve device for a sealed storage battery, which is provided with a cross passage connecting the cap-like lid to the internal space.
