Zusammenfassung:	To provide a high-quality corrugated holder with excellent durability and reliability.SOLUTION: A manufacturing method for a corrugated holder 7 comprising a pair of annular members 8 and a plurality of fastening members (rivets 9) in which the pair of annular members 8 is connected so as to be superimposed in an axial direction, includes a heat treatment step of performing heat treatment for an unquenched annular member 8 made of a press-molded product of a steel plate. In the heat treatment step, a primary heat treatment of performing soft nitriding treatment for the unquenched annular member 8 at a temperature of 400 to 590°C, and a secondary heat treatment of holding the annular member 8 subjected to the soft nitriding treatment at a temperature of 180 to 200°C are executed.SELECTED DRAWING: Figure 2 【課題】耐久性及び信頼性に富む高品質の波形保持器を提供する。【解決手段】一対の環状部材８と、一対の環状部材８を軸方向に重ね合わせた状態で結合した複数の締結部材（リベット９）とを備えた波形保持器７を製造するための方法であって、鋼板のプレス成形品からなる未焼入れの環状部材８に対して熱処理を施す熱処理工程を含む。この熱処理工程では、未焼入れの環状部材８に対して４００～５９０℃の温度で軟窒化処理を施す一次熱処理と、軟窒化処理が施された環状部材８を１８０～２００℃の温度で保持する二次熱処理と、を実行する。【選択図】図２
