  • the rear end 22R of the enlarged diameter portion 22 is located behind the front end 18F of the sheath 18. According to this configuration, when a backward tensile force acts on the shielded electric wire 10, the front end portion of the sheath 18 is caught on the inner peripheral surface of the enlarged diameter portion 22, so that the relative displacement of the shielded electric wire 10 to the rear is caused. Can be prevented.

  • the front end 20F of the sleeve 20 is located in front of the front end 18F of the sheath 18. Therefore, when the sleeve 20 is covered with the sheath 18, the positional relationship of the sleeve 20 with respect to the sheath 18 in the front-rear direction cannot be known.
  • a notch 23 is formed at the front end portion of the sleeve 20 to expose the front end 18F of the sheath 18 to the outer peripheral surface side of the sleeve 20.
  • the notch 23 is opened in an oval shape long in the front-rear direction, and has a window hole shape in which the opening edges are continuous over the entire circumference. Therefore, the notch 23 does not open to the front end 20F of the sleeve 20. If the front end 18F of the sheath 18 is located within the opening region of the notch 23 when looking into the notch 23 from the outer peripheral side of the sleeve 20, the positions of the front end 20F of the sleeve 20 and the front end 18F of the sheath 18 The relationship can be confirmed through the notch 23. As a result, the sleeve 20 can be arranged at an appropriate position with respect to the sheath 18.
