<p>PURPOSE:To prevent the overfilling of gas by detecting the size of a gas bomb, and comparing and detecting the classification of the wind bag of the gas bomb to be filled up. CONSTITUTION:A size detecting part 3 of a gas bomb, a wind bag weight input part 4 and a sign state detecting part 5 are provided at a gas filling device so that the size of the gas bomb is detected and the classification of the wind bag of the gas bomb to be filled up is compared and detected. The overfilling of gas is thus prevented as well as the filling of gas in the gas bomb can be done according to the size of the gas bomb.
