the apparatus being characterized in that a concave portion configured to allow insertion of the first end portion of the first rod-shaped member (2A, 2B) is provided in the first terminal member, wherein an insertion depth of the first end portion of the first rod-shaped member (2A, 2B) is smaller than a depth of the concave portion of the first terminal member, so that an end surface surrounding the concave portion of the first terminal member does not make contact with the first rod-shaped member (2A, 2B); wherein the second rod-shaped member (2C, 2D) and the third terminal member are fixed to each other, and the second rod-shaped member (2C, 2D) and the fourth terminal member are not fixed to each other; wherein a further concave portion configured to allow insertion of the second end portion of the second rod-shaped member (2C, 2D) is provided in the fourth terminal member, and an insertion depth of the second end portion of the second rod-shaped member (2C, 2D) is smaller than a depth of the further concave portion of the fourth terminal member, so that an end surface surrounding the concave portion of the fourth terminal member does not make contact with the second rod-shaped member, and wherein a driving device (4A, 4B) is connected to the fourth terminal member. a first rod-shaped member (2A, 2B) including a magnetic material;
