ELECTROCAST BEARING AND METHOD OF MANUFACTURING SAME

摘要

Fine particles (6) are dispersed and held in an electrocast part (4), and fine particles (6) exposed from the outer peripheral surface (4a2) of the electrocast part (4) are molten to form micro-projection parts (60) integrated with a resin part (5). The micro-projection parts (60) intrude into fine particle scars (4c) formed in the electrocast part (4) and exhibit an anchor effect, whereby the fixing force between the resin part (5) and the electrocast part (4) can be increased.
