The present invention relates to a spine traction device for towing and stretching a spine in a state that a person seats or lies thereon. Specifically, the spine traction device includes: a support member (100) for supporting a hip of a user to safely relax a spine by a simple action of the user a central member (200) coupled to the horizontal member (100) by a hinge structure (300) a seatback member (400) freely moving in the longitudinal direction of the central member (200) a neck-support member (500) freely moving in the longitudinal direction of the seatback member (400) a movement unit (600) for moving the neck-support member (500) depending on movement of the seatback member (400) and a length control unit (700). The present invention configured as described above has an effect on relaxing the spine by a user action of simply bending a back backwards, since the seatback member (400) is pushed up by the length control unit (700) when the central member (200) is rotated from the support member (100), and the neck-support member (500) is prolonged together with the seatback member (400) by the movement unit (600). In addition, the seatback member (400) and the neck-support member (500) are prevented from being excessively prolonged by an elastic unit (800) included in a wire (610) of an elastic material, the central member (200), and the neck-support member (500), so that an accident occurring due to excessive relaxation of a spine or a cervical spine is prevented.COPYRIGHT KIPO 2016본 발명은 사람이 앉거나 누운 상태에서 척추를 견인하여 스트레칭하는 척추견인기에 관한 것으로, 상세하게는 사용자의 단순 동작만으로 척추가 안전하게 이완되도록 사용자의 엉덩이를 받치는 받침부재(100)와 그 수평부재(100)의 힌지구조(300)로 결합된 중심부재(200), 그 중심부재(200)의 길이방향으로 자유이동되는 등받이부재(400), 그 등받이부재(400)의 길이방향으로 자유이동되는 목받이부재(500), 등받이부재(400)의 이동에 따라서 목받이부재(500)를 이동시키는 이동수단(600) 및 길이제어수단(700)을 포함하여 구성된다.이렇게 구성된 본 발명은 중심부재(200)가 받침부재(100)로 부터 회전될 경우에 길이제어수단(700)에 의해 등받이부재(400)가 밀려 올라가게 되고, 이동수단(600)에 의해서 등받이부재(400)와 함께 목받이부재(500)가 길어지게 됨으로써, 사용자가 단순히 등을 젖히는 동작만으로 척추가 이완되는 효과가 있다.또한, 탄
