摘要：To provide a aling plate comprising an explosion-proof valve which facilitates tting of a valve opening pressure and is capable of preventing a groove part from being broken by a repeated stress before reaching the valve opening
pressure.SOLUTION: In a structure of an explosion-proof valve 22 including a thin plate part 24 which is thinner than a plate 19, a valve opening part 25 in which the thin plate part is partially projected in a thickness direction, and a groove part 29 which parates the valve opening part from the thin plate part and functions as a break line, the groove part is formed linearly in such a manner that both ends 34 and 35 are parated without completely enclosing the valve opening part. A straight line 37 connecting both the ends is provided at a position across the valve opening part, and a fold line 38 which is substantially in parallel with the straight line is t at a position on an opposite side to a central part 50 in a length direction of the groove part across the straight line, and out of the valve opening part. In the thin plate part, a portion between both the ends of the groove part and the fold line becomes a free break region 31 which is freely broken continuously to a break of the groove part. A aling plate is configured in such a manner that the valve opening part is folded along the fold line by the break of the groove part and the continuous free break of the thin plate part in the free break region and that the
explosion-proof valve is opened.SELECTED DRAWING: Figure 10申请人：大和製罐株式会社
