A rehabilitation device is adapted for wrist rehabilitation, and includes two magnetic actuators and a movable frame unit. Each of the magnetic actuator includes a motor, a rotating shaft, a rotating member, and two magnetic coupling subunits that are respectively connected to the motor and the rotating shaft. Each of the magnetic coupling subunits includes a magnetic ring that has a plurality of N pole portions and a plurality of S pole portions alternately arranged about a center of the magnetic ring. For each of the magnetic actuators, when one of the magnetic coupling subunits that is connected to the motor is driven by the motor to rotate, the other one of the magnetic coupling subunits that is connected to the rotating shaft is urged to rotate by attraction between the magnetic rings of the magnetic coupling subunits such that the rotating shaft and the rotating member rotate. |
