Wire harness with pipe and flexible holder that holds an electric wire

1. A wire harness comprising:

an electric wire;

a pipe through which the electric wire is inserted; and

a flexible holder that is provided between an end of the pipe and the electric wire, and that holds the electric wire, wherein:

the holder surrounds the electric wire and is inserted into the end of the pipe,

a groove extending along a circumferential direction of the holder and facing an inner circumferential surface of the pipe is provided on an outer circumferential surface of the holder, and

the end of the pipe is crimped and the holder is flexurally deformed, whereby the inner circumferential surface of the pipe and the outer circumferential surface of the holder are brought into intimate contact with each other, and an inner circumferential surface of the holder and an outer circumferential surface of the electric wire are brought into intimate contact with each other, a crimped portion of the end of the pipe being reduced in diameter inward in a radial direction of the pipe and being engaged with the groove of the holder.

2. The wire harness according to claim 1 , wherein

a fastener that fastens an outer circumferential surface of the end of the pipe is provided on the outer circumferential surface of the end of the pipe.

3. The wire harness according to claim 1 , wherein

the holder includes a flange that is located outside the pipe and covers an end edge of the pipe.

4. The wire harness according to claim 1 , wherein

the holder has a tubular shape,

a pair of separation surfaces extending along an axial direction and separable from each other are provided in a portion of the holder in the circumferential direction, and

the separation surfaces abut against each other due to the end of the pipe being crimped and the holder being flexurally deformed.

5. The wire harness according to claim 1 , wherein

the holder is formed by a pair of half bodies each having a half-tube shape, and

both end surfaces in a circumferential direction of the pair of half bodies abut against each other due to the end of the pipe being crimped and the pair of half bodies being flexurally deformed.

6. The wire harness according to claim 1 , wherein

the holder has a cylindrical main body, and an outer circumferential surface of the main body is in contact with the inner circumferential surface of the pipe on both sides of the groove.

7. The wire harness according to claim 1 , wherein

a portion of a bottom surface of the groove is separated from the inner circumferential surface of the pipe, and a space is formed between the portion of the bottom surface of the groove and the inner circumferential surface of the pipe.

8. The wire harness according to claim 1 , wherein

the groove is provided in the holder at a predetermined depth, the predetermined depth of the groove is greater than a wall thickness of the pipe, and the predetermined depth of the groove is equal to or greater than a flexural deformation depth of the pipe.

9. The wire harness according to claim 1 , wherein

in a cross-sectional view of the wire harness, a portion of the inner circumferential surface of the holder is in contact with a portion of the outer circumferential surface of the electric wire over the entire length of the holder.
