Abstract
A pressure relief device for a high-pressure vessel comprises: a cap member having a space part formed therein; and a piston member having a first chamber part, and dividing the space part of the cap member into a second chamber part and a third chamber part, and thus, when fusible alloy is molten, the molten fusible alloy sequentially flows into the first chamber part and the second chamber part so that leakage of the molten fusible alloy to the outside can be prevented.
