される請求項１の脱気装置。[Claims for Utility Model Registration] 1. A vacuum chamber 1, a vacuum device 12 connected to the vacuum chamber 1, and a gas-permeable porous tube 2 disposed in the vacuum chamber 1, In a degassing device that degass dissolved gas in a liquid flowing in a porous tube 2, the outlet side of the porous tube 2 is led out from the vacuum chamber 1 and becomes an outlet side pipe 7 to degas the liquid. Further, the vacuum chamber 1 is connected to the atmosphere through an opening/closing means 14, and when the deaerator is stopped, the opening/closing means 14 is operated to open for a predetermined period of time, whereby the vacuum chamber 1 is connected to the atmosphere. A deaerator characterized in that the pressure is kept at normal pressure. 2. At least the outlet side of the porous tube 2 is integrally penetrated through the vacuum chamber 1 without providing a connection part and taken out to the outside to become the outlet side pipe 7,
2. The degassing device according to claim 1, wherein the penetrating portion (4) is hermetically sealed by a sealing member (5).
