<p><P>PROBLEM TO BE SOLVED: To provide an actuator which can take out various outputs, and a massage machine provided with the same. <P>SOLUTION: The actuator 11 includes stators 16-19 generating a magnetic force by being excited, movable members 21-24 moving by the magnetic force generated by the stators, a bag-like body 20 arranged within a movable member's moving range in a state of enclosing a fluid and deformable to form a localized expansion site when externally pressed by the moving movable member, and a controller for controlling the excitation of the stators. The actuator 11 gains the expansion power of the expansion site in the bag-like body as an output, wherein three or more displacement sections that can be the expansion site by displacing are arranged side by side on a side, and the controller controls the excitation of each stator so that a direction in which a displacement section among the respective displacement sections that has displaced and become the expansion site appear in turn is two or more directions including one direction connecting one displacement section and another displacement section by a straight line. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
