Abstract: The casting mold is provided with: the molding wall portion forming the internal space; and the filling ports that open to the molding wall portion and that allow the molten metal to flow into the internal space. In this configuration the channel center lines of the filling ports intersect the surface of the heater at the non-perpendicular contact angle.

Abstract: The casting mold is provided with: the molding wall portion forming the internal space; the supporting portion supports the heater to the molding wall portion; and the filling port allows the molten metal to flow into the internal space. The heater has: the end portion (the fixed portion) supported by supporting portion; and the extending portion extended from the end portion. The internal space has: the supporting region accommodating the end portion; and the extending region accommodating the extending portion. The filling ports respectively open to the portions of the molding wall portion facing the supporting regions.

Abstract: The heater (structure) has the gaps facing the molding wall portion of the casting mold. The casting mold is provided with: the molding wall portion forming the internal space; and the gap-portion filling ports (filling ports) that open to portions of the molding wall portion facing the gaps of the heater and that allow the molten metal to flow into the internal space.

Abstract: A caliper includes a hydraulic linking channel provided in a bridge section linking hydraulic cylinders, on an inner caliper section side, and hydraulic cylinders, on an outer caliper section side, to a cylinder-side hydraulic channel disposed on the back end of each respectively. A connecting channel forming section, which corresponds to each cylinder-side hydraulic channel and the hydraulic linking channel is provided, in advance, in a core used during casting of the inner caliper section, the outer caliper section, and the bridge section, and is formed by setting in a situation to be embedded at the same time as each caliper section and the bridge section are being integrally cast.
