To provide a sheathing member of an electric wire capable of suppressing deterioration in waterproof performance even when internal pressure is changed due to heat radiation from the electric wire inserted into an inside of the sheathing member.SOLUTION: A sheathing member 1 can be inserted into an electric wire W internally. The sheathing member 1 comprises a first cylindrical body 10 having a hollow section 11 into which the electric wire W is inserted and an opening 12 from which the electric wire W is drawn, and a second cylindrical body 20 provided so as to be extended from the first cylindrical body 10 so as to cover an outer periphery of the electric wire W drawn out from the opening 12. The first cylindrical body 10 has a vent section 30 through which moisture cannot pass and air can pass. The second cylindrical body 20 is made of a material softer than a material constituting the first cylindrical body 10.SELECTED DRAWING: Figure 1

    【課題】外装部材の内部に挿通する電線からの放熱等に起因して内部圧力が変化する場合であっても、防水性能の低下を抑制可能である、電線の外装部材を提供すること。【解決手段】外装部材1は、電線Wを内部に挿通可能である。外装部材1は、電線Wが挿通される中空部11及び電線Wが引き出される開口部12を有する第1筒状体10と、開口部12から引き出される電線Wの外周を覆うように第1筒状体10から延出するように設けられる第2筒状体20と、を備える。第1筒状体10は、水分は通過不能であり且つ空気は通過可能な通気部30を有する。第2筒状体20は、第1筒状体10を構成する材料よりも柔軟な材料から構成される。【選択図】図1
