Abstract: A casting apparatus for a cylinder block prevents deformation of a core pin and a cast passage formed by the core pin due to impact of molten metal when casting. Embodiments include a first side mold having a first core pin, a second side mold having a second core pin, a third mold having a molten metal inlet, and a metal dowel. The molten metal inlet is disposed so the inflow direction of molten metal intersects the axial direction of the first and second core pins, which are butted against each other at mold clamping and constitute a core for forming a main gallery for lubricant. The metal dowel is disposed between the molten metal inlet and a butt portion between the first and second core pins so that the butt portion is covered by the metal dowel from the upstream side in the inflow direction of the molten metal.
