<p>A pressure regulating mechanism for hole sealing plate capable of preventing a pressure vessel from being exploded by an abnormally increased pressure inside the pressure vessel for cells and capacitors even if the pressure vessel is not provided with a rubber burst plate with which it is difficult to control a burst pressure, comprising a burst plate (7) formed integrally with a resin hole sealing plate body (2) which closes the opening of the pressure vessel, a thin wall part (8) smaller in thickness than that of the burst plate (7) and formed integrally between the hole sealing plate body (2) and the burst plate (7), and an inclined surface part (9) which gradually increases in its thickness from the thickness of the thin wall part (8) and is positioned on the peripheral edge part of the burst plate (7).</p> |
