To provide a cutoff tool for a joint part of a wire harness part that facilitates management on the injection amount of a cutoff agent.SOLUTION: The present invention relates to a cutoff tool which comprises a joint part between the other end of a drain line of a shield wire having one end cut off, and one end of a core conductor of a coated electric wire, and connects the coated electric wire to an earth circuit in an electronic control unit, and the cutoff tool consists of a main body and a lid. The inside of the main body is partitioned with a partition wall into a cutoff chamber of small capacity and a cutoff agent reservoir chamber having larger capacity than the cutoff chamber. The cutoff chamber is an arrangement part for a core conductor exposure part from a coating end part of the coated electric wire, and while the partition wall is provided with an opening for core conductor penetration, the cutoff agent reservoir chamber is provided with a positioning retention base for the joint part, and the lid is provided with a cutoff agent injection port for injecting a cutoff agent into the cutoff chamber, the coating inside being deaired from the other end of the coated electric wire.SELECTED DRAWING: Figure 3

【課題】ワイヤハーネスのジョイント部の止水具において、止水剤の注入量の管理を容易とする。【解決手段】一端がカットオフされるシールド線のドレン線の他端と被覆電線の芯線の一端とのジョイント部分を備え、前記被覆電線を電子制御ユニット内のアース回路と接続する止水具であって、本体と蓋とからなり、該本体の内部を仕切壁で仕切って小容積の止水室と該止水室より容積が大きい止水剤溜め室とに仕切り、前記止水室は前記被覆電線の被覆端部から芯線露出部の配置部とし、前記仕切壁に芯線貫通用開口を設けると共に、前記止水剤溜め室に前記ジョイント部分の位置決め保持台を設けており、かつ、前記蓋に止水室へ止水剤を注入する止水剤注入口を設けていると共に、前記被覆電線の他端から被覆内部のエア抜きがされるものである。【選択図】図３
