パツキング１１が装着されている。 In the drawings, reference numeral 1 indicates a cylindrical plug body made of a synthetic resin molded body, and the cylindrical plug body 1 includes a cylinder body 1' and a top wall 2.
It consists of The top wall 2 covers the upper space of the cylindrical body 1', has a larger diameter than the cylindrical body 1', and has a coin groove 3 on its outer surface. The above structure is the same as that of a conventional explosion-proof plug, but according to the present invention, a recess 5 is provided in the center of at least one side wall 4 of the coin groove 3, and in the illustrated example, both side walls 4, 4.
5 is formed. The recesses 5, 5 are formed in the top wall 2.
The side wall 4a, which is open at the upper surface and forms the recess 5, is arc-shaped and has a small exhaust hole 7 that communicates between the recesses 5, 5 and the cylindrical internal space 6 below the top wall 2. In the cylindrical internal space 6 of the cylindrical plug body 1, an explosion-proof filter 8 is fixedly installed near the top wall 2, and a splash-proof plate 9 is fixedly installed in the lower part of the explosion-proof filter 8.
A screw thread 10 is provided on the outer circumferential surface near the top wall 2 and is detachable from the liquid inlet or exhaust port of the storage battery, and an annular packing 11 is provided between the thread 10 and the lower surface of the outer peripheral protruding edge of the top wall 2. It is installed.
尚、頂壁２の上面中心に、該両側の円弧状側壁
４ａ，４ａの上端縁に沿い小さい円弧状突縁１

全性が付与される。 The operation of the explosion-proof plug of the present invention is as follows:
Since it is provided on the arc-shaped side wall 4a of the recess 5 formed on the side surface of the coin groove 3, there is no risk of foreign dust etc. adhering to and accumulating in the small hole 7, and there is no possibility that it will be generated inside the storage battery during use. The gas passes through the cylindrical inner space 6 to remove the electrolyte acid mist, and then is discharged to the outside through the small exhaust hole 7 provided in the arcuate side wall 4a and the recess 5 space. Further safety is provided when a pair of small holes 7 are provided as shown in the figure.
