To provide an electric wire protection member capable of performing smooth bending and stretching motions while satisfactorily protecting an electric wire of a wire harness, and a manufacturing method of the electric wire protection member.SOLUTION: The present invention relates to an electric wire protection member 10 which covers and protects a circumference of an electric wire of a wire harness 1, comprising: an exterior member 20 constituted of a tubular body which is formed from a resin having flexibility and in which crest portions 21 and valley portions 22 are formed alternately in an axial direction over a circumferential direction orthogonal to the axial direction; and a cylindrical bending regulation member 30 which is accommodated inside of the exterior member 20 and enabled to be bent in one direction with one side portion 30a defined as the inside. The bending regulation member 30 includes a plurality of divided cylinders 33 which are coupled by a coupling part 34 formed in the one side portion 30a by forming notches 32 while leaving the one side portion 30a. The notches 32 are formed so as to be tilted in the axial direction with respect to a radial direction of the bending regulation member 30.SELECTED DRAWING: Figure 2

    【課題】ワイヤハーネスの電線を良好に保護しつつ円滑な屈伸動作が可能な電線保護部材及び電線保護部材の製造方法を提供すること。【解決手段】ワイヤハーネス1の電線の外周を覆って保護する電線保護部材10であって、可撓性を有する樹脂から形成され、軸方向に直交する周方向にわたって山部21及び谷部22が軸方向に交互に形成された管体からなる外装部材20と、外装部材20の内部に収容され、一側部30aを内側とする一方向への屈曲が可能とされた筒状の屈曲規制部材30と、を備え、屈曲規制部材30は、一側部30aを残して切込み部32を形成することにより一側部30aに形成された連結部34で連結された複数の分割筒部33を有し、切込み部32は、屈曲規制部材30の径方向に対して軸方向へ傾斜するように形成されている。【選択図】図2
