PROBLEM TO BE SOLVED: To provide a curvature regulating member capable of regulating curvature in a predetermined direction of a protective tube for protecting a wire harness.SOLUTION: A curvature regulating member 130 to be inserted into a corrugated tube is made of a synthetic resin and is integrally provided with a band portion 31 and a plurality of pieces 33 standing upright from both ends in the width direction of the band portion 31. The bending regulating member 130 is bendable in a direction in which the band portion 31 becomes inside and the pieces 33 becomes outside. In the opposite direction, the bending is restricted by abutting of adjacent pieces 33. The pieces 33 are provided with a plate portion 34 having a quadrangular plate shape, and two corner portions on the side of the plate portion 34 away from the band portion 31 are rounded.SELECTED DRAWING: Figure 2 【課題】ワイヤハーネスを保護する保護チューブの所定方向への湾曲を規制することができる湾曲規制部材を提供する。【解決手段】コルゲートチューブ内に挿入される湾曲規制部材１３０は、合成樹脂で構成され、帯部３１と、帯部３１の幅方向の両端から立設した複数の駒部３３と、を一体に備えている。湾曲規制部材１３０は、帯部３１が内側かつ駒部３３が外側となる向きで湾曲可能であり、逆向きには、隣り合う駒部３３同士が当接することで湾曲が制限されている。駒部３３は四角形板状の板部３４を備えており、この板部３４における帯部３１から離れた側の二箇所の角部分には丸みがつけられている。【選択図】図２
