The present invention is composed of a base frame in contact with the ground and a moving frame stacked on the top surface of the base frame and moving in the longitudinal direction of the base frame, wherein the user's neck is seated on the top surface of the moving frame. It is formed with a seating portion formed by the user, and when the user seats the neck portion, the moving frame moves in the longitudinal direction and relates to a pillow-type neck retractor in which the user's neck portion is relaxed. At one end of the base frame, a pair of shoulder support members are formed to support the user's shoulders, and when air is injected between the shoulder support members and the moving frame, an air pocket in which the volume expands in the longitudinal direction of the base frame is provided. The both ends are fixed to the shoulder support member and the moving frame, respectively, so that the shoulder support member contacts the user's shoulder and the user's neck is seated on the seating portion, so that the air inlet is inserted into the air pocket. When air is injected by the air bag, the volume expands long in the longitudinal direction of the base frame while the moving frame on the upper surface of the base frame moves in the longitudinal direction of the base frame to relax the user's neck, or the moving frame 120, an inner space is formed by opening a lower surface, a rotation shaft is fastened to both ends of the moving frame through both sides of the moving frame, and a pinion gear having a rotation axis as a central axis is formed on the rotation shaft. The upper surface of the base frame is equipped with an air pocket that expands in volume in the longitudinal direction of the base frame when air is injected into the rack gear and the inside so as to be bitten by the pinion gear. Is fixed to the upper surface of the base frame or the inner surface of the moving frame adjacent to, the other end is fastened so as to rotate the rotating shaft to the
