A nozzle for spraying the mold release agent and a holding body for holding the nozzle are included in the spray device. The holding body is so constructed as to fit in an opening of a mold casting device in which a tip end of a sleeve of a feeder fits in order to feed molten metal, and the nozzle is so held by the holding body that its tip end can be extended from the holding body for a desired length and can be turned in a desired direction.
