The present invention relates to a pillow for a cervical vertebral tensile strength and for preventing snoring, which makes a force pushing a cervical portion, which is put together by a force in a slanting direction, which is applied when an air pocket filled by air is slantingly expanded to push a cervical portion below an ear in a back part of the neck of a user, and a force in a vertical direction according to a gravity of the head of the user, be applied in the longitudinal direction of the cervical portion, such that the cervical portion is stretched in the longitudinal direction of the cervical portion in order to correct a posture causing a cervical disc. The pillow comprises: a main body (10) which has a convex cervical support part (11) for supporting the cervical portion of a user, and a head supporting part (12) for supporting the head of the user in a rear portion continued with the cervical support part (11) a cervical tensile means in which, when an air pocket (20), mounted on a rear portion of the cervical support part (11) or below a bottom surface of a boundary between the cervical support part (11) and the head support part (12), receives air, the air pocket(20)expands slantingly towards the head of the user to press a contact portion of the back part of the neck of the user, and a force applied to the contact portion of the back part of the neck stretches the cervical portion in the longitudinal direction of the cervical part by means of a resultant force of a force in the slanting direction of the expanding air pocket (20) and a force of a weight of the head in the vertical direction, and when the air supply stops, the air filled in the air pocket (20) is discharged by means of pushing the head of the user to recover an original state and an anti-snoring means which drives the cervical tensile means when sounds or vibrations of snoring of the user are sensed, induces the head of the user to move, and prevents snoring.COPYRIGHT KIPO 2018본 발명은 공기가
