Next, after the peripheral wall portion 62 of the cover member 6 is attached to the electric wire holding portion 52 of the molding member 5, the outer peripheral surface 611a of the first guide tubular portion 611 is tightened by the first tightening member 8A, and the second The outer peripheral surface 621a of the second guide tubular portion 621 is tightened by the tightening member 8B, and the outer peripheral surface 62b of the end portion of the peripheral wall portion 62 on the sheath 4 side is tightened by the third tightening member 8C.

Next, the wire harness 1 is manufactured by winding the winding tightening portion 71 of the bracket 7 around the outer peripheral surface 5a between the pair of flange portions 511 and 511 of the molding member 5. After that, fastening members such as bolts and rivets are inserted into the through holes 720 formed in the fixing portion 72 of the bracket 7 and fixed to the vehicle body side.

(Operation and Effect of Embodiment)
According to the embodiment described above, the following actions and effects can be obtained.

In the cover member 6, the inner peripheral surfaces of the insertion holes 61a and 62a are in contact with the outer peripheral surfaces of the first and second insulated electric wires 2 and 3. As a result, the vibration of the vehicle is applied to the first and second insulated wires 2 and 3, the first and second insulated wires 2 and 3 are strongly bent, or the first and second insulated wires are installed. Even if the insulated wires 2 and 3 of FIG. 2 are pulled, the origin of deformation of the first and second insulated wires 2 and 3 due to the vibration, bending, or pulling is from the end surface 5b of the molding member 5 to the tip of the cover member 6. To the surface (the tip surface of the first guide cylinder portion 611 and the tip surface of the second guide cylinder portion 621). As a result, the vibration of the vehicle is applied to the first and second insulated wires 2 and 3, the first and second insulated wires 2 and 3 are strongly bent, or the first and second insulated wires are installed. Even if the insulated electric wires 2 and 3 are pulled, the load applied between the molding member 5 and the first and second insulated electric wires 2 and 3 is reduced, and the molding member 5 and the first and second insulated electric wires 2 and 3 are reduced. It is possible to suppress the possibility of forming a gap between the insulated wires 2 and 3. Therefore, it becomes possible to prevent the deterioration of the waterproof property between the molded member 5 and the first and second insulated wires 2 and 3.

The sheath 4 and the molding member 5 adhere to each other because the surface of the sheath 4 melts with the molding member 5 due to heat at the time of molding the molding member 5, so that the waterproofness between the molding member 5 and the sheath 4 increases. This makes it possible to prevent water from entering the sheath 4 through the gap between the molding member 5 and the sheath 4. Further, since the sheath 4 is pressed in the radial direction by the tightening force of the tightening portion 71 of the bracket 7, the water blocking property between the molding member 5 and the sheath 4 is further enhanced.

Since the inner peripheral surfaces of the insertion holes 61a and 62a of the cover member 6 are in elastic contact with the outer peripheral surfaces of the first and second insulated wires 2 and 3, the cover member 6 and the first and second insulated wires 2 and 3 are in contact with each other. The waterproofness between 3 and 3 is increased. Accordingly, even if the insulators 22 and 32 and the molding member 5 are not melted by the heat at the time of molding, the insulation between the first and second insulated wires 2 and 3 and the molding member 5 is prevented. It is possible to suppress the infiltration of water into the sheath 4. Further, the outer peripheral surface 611a of the first guide tubular portion 611 of the cover member 6 is fastened by the first fastening member 8A, and the outer circumferential surface 621a of the second guide tubular portion 621 is fastened by the second fastening member 8B. Therefore, the waterproof property between the cover member 6 and the first and second insulated wires 2 and 3 is further enhanced. Further, since the outer peripheral surface 62b of the end portion of the peripheral wall portion 62 on the sheath 4 side is clamped by the third clamping member 8C, the water entering between the cover member 6 and the molding member 5 can be stopped further. You can

Since the cover member 6 is made of a rubber elastic body, it is possible to guide the first and second insulated wires 2 and 3 (fix the lead-out direction of the first and second insulated wires 2 and 3). However, even if the first and second insulated wires 2 and 3 are bent due to vehicle vibration or the like, the cover member 6 is also bent following the bending of the first and second insulated wires 2 and 3. The damage to the first and second insulated wires 2 and 3 can be suppressed.

Furthermore, since the first and second insulated wires 2 and 3 can be arranged linearly (so as to have straight portions) in the wire holding portion 52, these insulated wires 2 and 3 can be arranged inside the wire holding portion 52. Problems that may occur when bending, for example, the insulators 22 and 32 are stretched and thinned on the outer diameter side of the curve, and the thinned portions of the insulators 22 and 32 are not suitable for molding the molding member 5. The molded member 5 can hold the first and second insulated wires 2 and 3 without causing a problem of being damaged by heat.
