PROBLEM TO BE SOLVED: To provide a method for molding a chain-positioning member that can readily mold a resin chain-positioning member having a smooth sliding surface without any warpage.SOLUTION: The method for molding a chain-positioning member for injection molding the resin chain-positioning member having the chain sliding surface at one side surface in the longitudinal direction thereof includes a step of injecting a resin toward a direction along a side wall surface 21a corresponding to the sliding surface in a cavity 21 of a molding die 2 to mold the whole body of the chain-positioning member. 【課題】反りの発生がなく、円滑な摺動面を有する樹脂製のチェーン位置決め部材を容易に成形することができるチェーン位置決め部材の成形方法を提供すること。【解決手段】長手方向の一側面にチェーンの摺動面を有する樹脂製のチェーン位置決め部材を射出成形するチェーン位置決め部材の成形方法であって、成形金型２におけるキャビティ２１内の摺動面に対応する側壁面２１ａに沿う方向に向けて樹脂を注入することにより、チェーン位置決め部材の全体を成形することを特徴とする。【選択図】図３
