PROBLEM TO BE SOLVED: To make it possible to position a tread ring with a high accuracy and improve uniformity of a tire.SOLUTION: A spoke casting device for an airless tire includes: a casting metal mold which concentrically holds a tread ring and a hub between upper and lower metal molds and forms a cavity therebetween; positioning means for concentrically positioning the hub and the tread ring; and mold removal means which pushes out an airless tire after casting from the lower metal mold in a metal mold opening state. The positioning means has first positioning means which includes an outer peripheral surface contact part which contacts an outer peripheral surface of the tread ring and positions the tread ring.

    【課題】トレッドリングを高精度で位置決めし、タイヤのユニフォーミティを向上させる。【解決手段】上下の金型間でトレッドリングとハブとを同心に保持するとともに、その間にキャビティを形成する注型金型、前記ハブとトレッドリングとを同心に位置決めする位置決め手段、及び金型開状態において、注型成形後のエアレスタイヤを前記下の金型から押し出す脱型手段を具える。前記位置決め手段は、トレッドリングの外周面と当接してトレッドリングを位置決めする外周面当接部を含む第1の位置決め手段を有する。【選択図】図5
