A power-driven traction device for neck physical therapy includes a rail platform disposed on a base and a traction mechanism used for drawing a user's neck disposed on the platform. The traction mechanism includes a neck rest portion and a drive portion. The neck rest portion is coupled with the drive portion. The drive portion is slidably disposed on the rail platform and connected with a power-driven drive device. The power-driven drive device is connected with the drive portion to bring the neck rest portion to slide backward and forward on the rail platform in a longitudinal direction. It is convenient for the user to operate the power-driven traction device by himself. The force to draw the user's neck can be controlled finely and well.
