Abstract (en)

A method of manufacturing a cylinder block including a semicircular bearing section that rotatably supports a crankshaft is provided. The method of manufacturing a cylinder block includes pressure-injecting molten metal into a cavity formed inside a metal mold, and sliding a pressure pin disposed in the metal mold after the pressure-injecting of the molten metal and thereby applying a pressure to the molten metal injected in the cavity, in which in the applying of the pressure to the molten metal, the pressure pin is slid toward an area where the bearing section is formed, a tip of the pressure pin protruding in an arc shape so as to conform to a shape of the bearing section.
