たことを特徴とするボイスコイル型モータ。 On the opposing inner sides of the yokes arranged above and below, there are permanent magnets with different polarities on adjacent surfaces toward the inner surface of the yoke with the center of one surface as the border, and magnetic poles magnetized perpendicular to the inner surface of the yoke. A voice coil type in which permanent magnets are fixed so that they face each other, pillars are installed around the upper and lower yokes, a gap is formed between the permanent magnets, and a moving coil is placed in the center of the gap. In the motor, the strut, which is a component part, has a structure in which it is separated into a caulking rivet that is corrosion-resistant and easy to work with, and a spacer made of soft magnetic material with a corrosion-resistant surface that determines the length of the gap. A voice coil type motor characterized by:
