Since the thickness of the lower end portion on the side facing toward is 2.0 mm or more and 2.5 mm or less, when the peeling tool 10 is rotated, the covering portion W2 of the covered wire W moves from the rear side to the front side of the grip body 22. The grip body 22 is deformed into an elliptical shape having a long axis in the direction from the rear side to the front side.
However, if the third covered wire covering portion 128 is formed on the fifth guide body 120E and the sixth guide body 120F, even if the peeling tool 10 is rotated, the covering portion W2 of the covered wire W will be formed. Since it is pushed by the side surface of the sixth guide body of the sixth guide body on the sixth covered wire holding portion 122F side of the third covered wire covering portion 128 formed on the fifth guide body 120E and the sixth guide body 120F, the covered wire is covered. The covering portion W2 of W is not deformed into an elliptical shape having a long axis in the direction from the rear side to the front side of the grip body 22 from the rear side to the front side of the grip body 22.
Therefore, if the third covered wire covering portion 128 is formed on the fifth guide body 120E and the sixth guide body 120F, the covered portion W2 of the covered wire W goes from the rear side to the front side of the grip body 22. Since the grip body 22 is not deformed into an elliptical shape having a long axis in the direction from the rear side to the front side toward the side, even if the peeling tool 10 is attached to the covered wire W and rotated, the blade body 18 is used. Does not sufficiently penetrate into the covering portion W2 of the coated wire W, so that the blade body 18 penetrates too much into the covering portion W2 of the coated wire W, so that the core wire W1 of the coated wire W is not damaged.
