NOISE SUPPRESSION MEMBER

PROBLEM TO BE SOLVED: To provide a noise suppression member capable of suppressing a load from being applied between a corrugated tube and a magnetic core to each other.SOLUTION: A noise suppression member 1 includes an annular magnetic core and a case. The case has a first opening at one end of both ends in a first direction that is an insertion direction of a corrugated tube 2, and a second opening at the other end. A first restriction section 21 is provided on a first opening side, and a second restriction section 22 is provided on a second opening side. The first restriction section 21 is configured to restrict the corrugate tube 2 from being relatively displaced in a radial direction with respect to the case by being brought into contact with an outer periphery of an annular projecting portion 2A at a contact surface 21A, and the second restriction section 22 is configured to restrict the corrugate tube 2 from being relatively displaced in an axial direction with respect to the case by entering a recessed portion 2B provided between two annular projecting portions 2A, 2B.SELECTED DRAWING: Figure 5 【課題】コルゲートチューブと磁性体コアとの間で互いに負荷がかかるのを抑制可能なノイズ対策部材を提供する。【解決手段】ノイズ対策部材１は、環状の磁性体コアと、ケースとを有する。ケースは、コルゲートチューブ２の挿通方向である第一方向の両端のうち、一端に第一開口部、他端に第二開口部を有し、第一開口部側には第一規制部２１が設けられ、第二開口部側には第二規制部２２が設けられている。第一規制部２１は、当接面２１Ａで環状凸部２Ａの外周に当接することにより、コルゲートチューブ２がケースに対して相対的に径方向へ変位するのを規制可能に構成され、第二規制部２２は、二つの環状凸部２Ａ，２Ａ間にある凹部２Ｂに入り込むことにより、コルゲートチューブ２がケースに対して相対的に軸方向に変位するのを規制可能に構成している。【選択図】図５
