Zusammenfassung:	To provide a cooling hole guide for forming an enlarged part (100) through reamer processing on a cooling hole (280) of a rotor (45).SOLUTION: A cooling hole guide (120) includes a cutter guide (130) for insertion into a cooling hole (280) and a guide lock (140) for insertion into an adjacent cooling hole (290). The cooling hole guide (120) may further comprise a fitting plate (150) fitted with the cutter guide (130) and guide lock (140). An enlarged part (100) which is decentered is formed by: arranging the cutter guide (130) at the cooling hole (280) of a turbine rotor; arranging the guide lock (140) at the adjacent cooling hole (290); locking the guide lock (140) in the adjacent cooling hole (290); inserting a reamer tool (300) into the cutter guide (130); and performing reamer processing on the cooling hole (280).SELECTED DRAWING: Figure 4 【課題】ロータ（４５）の冷却穴（２８０）に拡大部分（１００）をリーマ加工するための冷却穴ガイドを提供する。【解決手段】冷却穴ガイド（１２０）は、冷却穴（２８０）に挿入するためのカッタガイド（１３０）と、隣接冷却穴（２９０）に挿入するためのガイドロック（１４０）とを含む。冷却穴ガイド（１２０）は、カッタガイド（１３０）及びガイドロック（１４０）が取り付けられる取付板（１５０）をさらに備えていてもよい。タービンのロータの冷却穴（２８０）にカッタガイド（１３０）を配置し、隣接冷却穴（２９０）にガイドロック（１４０）を配置し、隣接冷却穴（２９０）内でガイドロック（１４０）をロックし、リーマ工具（３００）をカッタガイド（１３０）に挿入し、冷却穴（２８０）をリーマ加工して中心のずれた拡大部分（１００）を作成する。【選択図】図４
