Abstract
A magnet holder for an electromagnetic diaphragm pump comprising a reinforcing member having at least in part thereof a width smaller than the distance between a pair of magnets placed in the predetermined positions in magnet insertion windows is provided integrally with the magnet holder between the pair of magnet insertion windows for juxtaposing and holding a pair of flat plate-shaped magnets in the same plane, so that the mechanical strength of the magnet holder is prevented from decreasing. And positioning members may be formed in the reinforcing member for pressing the pair of magnets inserted into the magnet insertion windows toward the diaphragms attached to opposite ends of the magnet holder, thereby positioning the magnets with enough accuracy and determining the distance between the magnets.
