摘要： A semi-closed type of breathing apparatus includes an air exhaling duct for guiding breathing air exhaled from a mouthpiece to a canister filled with a carbon dioxide remover, and an air inhaling duct for guiding the breathing air, from which carbon dioxide has been removed, to the mouthpiece. The air inhaling duct and the air exhaling duct are designed in a double-duct structure such that the air inhaling duct is surrounded by the air exhaling duct. That is, the ducts are formed in a single hose. Therefore, detachment of the breathing apparatus from a user is easily performed, the overall appearance of the apparatus is not marred, and the entire construction of the apparatus is simplified.
