PROBLEM TO BE SOLVED: To provide a sealing/pumping-up apparatus where a sealing agent leaked from a pressure relief valve hardly splashes about an operator on pressure relief. SOLUTION: The inside of a relay member 52 is divided partitioned by a partition wall 54 into a first room R1 and a second room R2. Next, a first connecting part 64 communicating with the first room R1 is projected towards outside, on the side of the first room R1 of the relay member 52 and a branch pipe 67 is connected to the first connecting part 64. Further, on the side of the second room R2 of the relay member 52, a second connecting part 65 communicating with the second room R2 is projected towards outside and the second connecting part 65 is opened in the atmosphere. A communicating hole 54A for connecting the first room R1 with the second room R2 is formed on a partition wall 54, and a capping member 56 is arranged in the first room R1 and covers the communicating hole 54A from the side of the first room R1. Further the capping member 56 is energized by a spring 60 and is arranged at a closing position P2 usually to close the communicating hole 54A. COPYRIGHT: (C)2007,JPO&INPIT
