A spoke casting device for integrally cast-molding a spoke of an airless tire includes a casting mold including upper and lower molds which relatively moves between mold closed and mold open states in tire axial direction, a positioning device which concentrically positions a hub and a tread ring with respect to the cast mold, and a demolding device which pushes out an airless tire from the lower mold in the open state. The cast mold concentrically holds the ring and hub between the upper and lower molds and forms a cavity for casting a spoke made of a polymer material between the ring and hub held in the closed state, and the positioning device includes a first positioning device including an outer peripheral surface contact portion such that the contact portion makes contact with outer peripheral surface of the ring and positions the ring with respect to the cast mold.
