• a main body that comes into contact with a posterior side of the neck when the tool is worn and receives an upward external force in a supine posture;
• a pair of jaw retainers that extend forward from the main body spaced apart by a distance equivalent to the diameter of the neck and come into contact with both sides of the lower jaw when the tool is worn;
• and
• a protruding section that is provided in the main body and applies stress in a direction of pushing up the lower jaw in a supine posture to the main body, wherein:
• the main body and the pair of jaw retainers are formed of a restorable member,
• the main body and jaw retainers deform, when the posture is changed from the supine posture, in conformity with the posture, and when the posture is changed to the supine posture, the external force received by the main body is made to act on the jaw retainers to retain the lower jawat a height at which the respiratory tract can be managed, and
