In the apparatus for supporting deep breathing, an air-blow-off hole of a pipe connected to a bag and the vicinity of a check valve are formed of an elastic material and a spiral cut for ventilating is formed in a direction of the circle of the air-blow-off hole of the pipe. The check valve is in the opening state if only the vicinity of the check valve is pressed from the outside with a weak force, and the expanded bag can be contracted by flowing backward the air from the inside of the bag to the pipe. As a result, a deep breathing for health can be mastered easily. Further, since the check valve has a spiral hinge connecting along the cut and the pipe and a valve plug are connected through the hinge, the quality of the hinge can be maintained for a long term. -16-
