PROBLEM TO BE SOLVED: To provide an adapter for deaeration inside a bag, which is generally applicable to bags widely without being limited to the one provided with a tightly sealing means such as a futon compression bag, without the risk of letting a stored object close the suction port of a hose of a suction implement during deaeration work and without the risk of air inflow since an opening is automatically closed as soon as the hose is pulled out after the deaeration is ended. SOLUTION: The adapter for the deaeration inside the bag comprises a hose adapter 1 connected to the hose of the suction implement and a closing implement 2 fixed to the optional part of the bag to be deaerated and engaged with the hose adapter 1. The hose adapter 1 or the closing implement 2 facing the inside of the bag is provided with one main suction port 5 and at least one sub suction port 5a on the part facing the inside of the bag. A closing means in the closing implement 2 makes ventilation through the closing implement 2 possible by engaging the hose adapter 1 to the closing implement 2 and interrupts the ventilation through the closing implement 2 by releasing the engaged state.
