<P>PROBLEM TO BE SOLVED: To provide a compact pressure release valve that is miniaturized compared with a conventional one in which a reinforcing ring is embedded in the peripheral base thereof. <P>SOLUTION: The pressure release valve comprises: a valve body 2 disposed inside the pressure release opening 10 of a sealing board 1; and a support member 3 for fixing the valve body 2 to the pressure release opening 10 by supporting a supported part 23 which is formed on the inner periphery and projects towards the outside of the pressure release opening 10. The valve body 2 has a seal lip 22 which closely contacts the inner peripheral surface of the pressure release opening 10 to perform valve opening operation when subjected to a given internal pressure in an inner space S of the sealing board 1, and the support member 3 has a plate spring 32 which is press-fitted into the inner peripheral surface of the pressure release opening 10. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
