摘要： In a cast product having a projecting portion that projects from a body portion and is integratedly cast with the body portion, a wall surface of the projecting portion is connected and integratedly cast with the body portion by means of a plurality of ribs. By this configuration, molten metal can easily flow up to a tip end of the projecting portion passing through the plurality of ribs from the body portion, and as a result, the generation of a casting cavity at the tip end of the projecting portion can be prevented. Furthermore, the strength of the projecting portion can be improved through reinforcement by means of the plurality of ribs.
