A gripper mechanism and a movement mechanism which utilize an electromagnetic actuator which can secure a sufficient thrust force at least at a certain level over a wide range of displacement. The movement mechanism includes a pair of electromagnetic actuators disposed inside a pair of rails and an intermediate actuator provided between the electromagnetic actuators. The electromagnetic actuators function as a gripper mechanism to be gripped by the rails. The electromagnetic actuators each include a displacement amplification mechanism including a magnetic body, and coils provided in the displacement amplification mechanism. A magnetic flux is generated in the magnetic body by passing an electric current through the coils so as to displace the displacement amplification points of the displacement amplification mechanism.
