An airway is secured without obstructing sleep even when the lingual radix falls into the airway. An airway expansion apparatus (1) is configured to include a pillow portion (2) that supports a cranial portion, a pair of left and right mandible holding portions (3) that hold the mandible coupled to the cranial portion at the temporomandibular joint, a first actuation mechanism (4) that causes the mandible holding portions to come into contact with the mandible, and a second actuation mechanism (5) that lifts the mandible holding portions with respect to the pillow portion with the mandible holding portions kept in contact with the mandible, in which the mandible is kept lifted. |
