Abstract
A device for manufacturing a field pole magnet body includes a reference jig having reference surfaces in a lengthwise direction, a width direction, and a thickness direction for positioning the plurality of cleaved and divided magnet fragments; a lengthwise direction pressing means that presses the magnet fragments from the lengthwise direction to the lengthwise direction reference surface; a width direction pressing means that presses them from the width direction to the width direction reference surface; and a thickness pressing means that presses them from the thickness direction to the thickness direction reference surface. The lengthwise direction pressing means is operated to press the magnet fragments in a state in which a pressing force of at least one of the width direction pressing means and the thickness direction pressing means is suppressed to be weaker than a pressing force generated by the lengthwise direction pressing means or is released.
