Claim 0:
1. An actuator comprising:
at least two iron cores, each iron core including a pole extending in a first direction parallel to a direction of gravity;
a permanent magnet disposed between the at least two iron cores so as to generate a magnetic field along a shape of a combination of the at least two iron cores arranged so as to be adjacent to each other in a direction not parallel to the first direction; and
a winding wound around the pole of each of the at least two iron cores,
wherein the at least two iron cores include:
a first iron core including a first pole extending in the first direction and a second pole extending in a second direction perpendicular to the first direction from one side end of the first pole; and
a second iron core including a third pole extending in a parallel manner to the extension direction of the first pole, and a fourth pole extending in a parallel manner to the extension direction of the second pole from one side end of the third pole and having an end face facing the end face of the second pole,
wherein the winding includes:
a first winding wound around the first pole; and
a second winding wound around the third pole,
wherein the permanent magnet is disposed between the end face of the second pole and the end face of the fourth pole so that a first pole and a second pole thereof are in contact with the end face of the second pole and the end face of the fourth pole, respectively.
