The neck traction device elongated a user's neck with the application of force on the user's shoulders. One embodiment includes a head pad, a vertically movably head support frame, a pivotally connected linkage member coupled to a shoulder frame element. The shoulder frame and shoulder pads are longitudinally movably mounted and the linked system exerts a longitudinal force on the user's shoulders when the user's head rests on the head pad and depresses the head pad. A biasing mechanism either upwardly supports the head frame or longitudinally limits the extension of the shoulder frame such that when the head is lifted off the head frame, the biasing mechanism raises the head pad and moves back the shoulder frame and pads. Alternatively, a transmission may be used to convert the substantially downward force due to the head weight to a longitudinal force on the shoulder pads.
