わるので、可動子の揺動量が変わる。In order to achieve the above object, an actuator according to the present invention comprises an iron core on which an exciting winding is wound, and a direction opposed to an end face of the iron core and orthogonal to an extending direction of the iron core. The permanent magnet is supported on a surface including the center line in the extending direction of the iron core, and the permanent magnet is provided at both ends in the swing direction of the permanent magnet. An N pole and an S pole are provided, and the width of the iron core is made larger than the width of the permanent magnet in the swing direction. Therefore, when the excitation winding is energized and the end face of the iron core is magnetized to the N pole, the magnetic resistance of the N pole becomes minimum at both ends of the end face of the iron core. For this reason, the one end of the permanent magnet where the S pole is magnetized is attracted to the N pole of one end of the end face of the iron core, and the other end where the N pole of the permanent magnet is magnetized is the N end of the other end of the end face of the iron core. Repelling with the poles, the permanent magnet swings toward one end of the iron core. Further, when the excitation coil is energized in the opposite direction, the end face of the iron core is magnetized to the S pole, so that the permanent magnet swings to the other side of the iron core. Further, by changing the amount of current supplied to the exciting winding, the attraction force and the repulsion force of both ends of the end face of the iron core change, so that the swing amount of the mover changes.

Each is excited to be a pole. The upper end of the iron core 3 on which the S pole is formed has the smallest magnetic resistance at both ends 3a and 3b close to the yoke 8 which forms a magnetic flux together with the iron core 3. Therefore, when the upper end of the iron core 3 is excited to be the S pole, the permanent magnet

Therefore, the permanent magnet 5 rotates around the pivot 4 in the direction of arrow A in the figure. At this time, the attractive force generated at the left end 3a of the iron core 3 and the repulsive force generated at the right end 3b of the iron core 3 are inversely proportional to the square of the distance to the permanent magnet 5, so that the current flowing through the exciting winding 2 is small. In the case of FIG. 2, the attraction force and the repulsion force are not sufficient, the amount of movement of the permanent magnet 5 is small, and the lever 6 rotates by the angle α. (Hereinafter, the state in which the permanent magnet 5 is tilted as shown in the figure is referred to as a first posture.)

第3の姿勢という)Next, as shown in FIG. 4, when a small current in the reverse direction is applied to the exciting winding 2, the exciting winding 2 is excited so that the upper end of the iron core 3 becomes an N pole. Are excited so that the upper ends of the yokes 8, 8 become S poles. When the upper end of the iron core 3 is excited to be an S pole, the right end 5b of the permanent magnet 5 facing the S pole on the S pole side is attracted to the right end 3b of the upper end of the iron core 3.
At the same time, the left end 5a on the N pole side of the permanent magnet 5 repels the left end 3a of the upper end of the iron core 3. For this reason, the permanent magnet 5 rotates around the pivot 4 in the direction of arrow B in the figure. In the case of FIG. 4 in which the current flowing through the exciting winding 2 is small, the attractive force and the repulsive force are not sufficient, the moving amount of the permanent magnet 5 is small, and the lever 6 rotates by the angle α. (Hereinafter, the state in which the permanent magnet 5 is tilted as shown in the figure is referred to as a third posture.)

向した状態の中立位置に保持される。When the energization of the excitation winding 2 is stopped, the excitation of the excitation winding 2 to the iron core 5 is demagnetized, and the left and right ends 3a and 3b of the upper end of the iron core 3 are connected to the left and right ends 5a and 5a of the permanent magnet 5. 5
Since the S and N poles are magnetized by the N and S poles of b, the left end 5a of the permanent magnet 5 is attracted to the right end 3a of the upper end of the iron core 3. Therefore, the permanent magnet 5 rotates about the pivot 4 in the direction of arrow A in the figure, and
As shown in (1), the permanent magnet 5 is held at a neutral position in a state facing the center of the upper end of the iron core 3.

By changing the direction of current flow to the
The moving direction and the moving amount of the permanent magnet 5 as the mover can be freely changed, and the permanent magnet 5 can be positioned at the neutral position and the first to fourth postures. Therefore, since an expensive motor is not required unlike the related art, the cost is low. In addition, mainly the excitation winding 2, the iron core 3 and the permanent magnet 5
Therefore, the number of parts can be reduced, the structure can be simplified, and the size can be reduced.
