PURPOSE: To provide a respiring bag for a half opening respiratory device preventing non-uniformity from being generated in respiration air in the respiring bag so that stable diving can be performed.
CONSTITUTION: A respiring bag 3 for a half opening respiratory device of diving respiratory device in this invention is constituted such that the bag is extended/ contracted by an inflow/outflow of respiration air, to provide partitions 53 for dividing space in the respiration bag 3 into a plurality of rooms 3A, 3B, and by providing the partitions 53, since the respiring bag itself, increasing strength, can be prevented from being deformed, largely deforming the respiring bag 3 is prevented even when generated non-uniform internal pressure. Accordingly, non-uniformly of respiration air is eliminated in the repiring bag 3, and stable diving can be performed.
