置。 A first mold and a second mold that are butted together to form a molding cavity, and one of the first mold and the second mold is provided so as to protrude into the cavity. a core for forming a hole in the molded product by coming into contact with the other mold, the core is movable along the direction in which the core is projected into the cavity, and has a maximum length that can be projected. The core is provided so as to be longer than the length of protrusion when the molds are matched together, and the other mold is brought into contact with the core by urging the core in the projecting direction to the one mold. 1. A molding device comprising: a biasing means that presses the core against the other mold and allows the core to move in the recessed direction.
