Auxiliary equipment such as an automatic door opening / closing unit is always powered regardless of whether the sliding door is opened or closed.

FIG. 8 shows a state in which a wire harness 70 is installed on a slide door 71 of an automobile. The wire harness 70 is installed from the vehicle body side (battery side) to the slide door side, and the slide door 71 is installed. While being housed in a bent state in a protector 72 made of synthetic resin provided inside, the protector 72 is routed from one opening of the protector 72 toward each auxiliary machine in the slide door, and is connected to each auxiliary machine by a connector. There is. The lower part of the protector 72 is provided with the other slit-shaped mouth portion 75 which is long in the front-rear direction, and the wire harness 70 is introduced into the protector from the vehicle body side through the mouth portion 75.

The protector 72 is made of synthetic resin and has a thin wall, and has a harness accommodating space inside. It has also been proposed that the wire harness 70 be biased upward in the protector by an elastic member such as a leaf spring. The protector 72 is fixed by fixing a plurality of brackets 61 integrally formed on the outer periphery.
This is performed by inserting a bolt (not shown) into the hole portion 62 of and fixing the bolt to the nut of the metal door panel 76 by screwing.

After the protector 72 is fixed to the door panel 76, a synthetic resin door trim 77 is fixed to the door panel 76 so as to cover the protector 72 from above. Fixing of the protector 72 is not limited to the bolt, and a locking clip (not shown) can be used. The locking clip has a plurality of flexible claw pieces radially, for example, and is the same as the means for fixing the door trim 77 to the door panel 76.
When the locking clip is used to fix the protector 72, it is only necessary to provide the door panel 76 with a hole for pushing the claw piece instead of the nut for engagement.

As described above, according to the first aspect of the present invention, the movable protector allows the harness protector to be easily and reliably attached to the harness protector even when the position of the mating mount is displaced. Since it can be mounted on the other side, the workability of mounting the harness protector is improved and the yield at the time of mounting work is improved. In addition, the movable fixed part absorbs distortion of the protector body during installation, external force after installation and thermal strain of the protector body, and the protector body does not deform, and the wire harness is stored smoothly without getting caught in the protector body. As a result, damage to the wire harness due to the wire harness protruding from the protector body is prevented, and the reliability of power supply of the power supply current and the signal current to the auxiliary equipment and the like is improved.

According to the second aspect of the present invention, one complete fixing portion serves as a fulcrum, and the other movable fixing portion absorbs the positional deviation of the mating attachment side and the distortion caused by the external force or heat. The fixing force is improved and the mounting workability is also improved.

According to the third aspect of the present invention, since the elastic member expands and contracts to absorb the displacement of the mating side mounting portion and the distortion of the protector body due to the external force and heat, the protector body is not deformed and the wire harness is prevented. Is smoothly and surely accommodated in the protector body. Since the elastic member can be easily formed on the protector body made of synthetic resin by integral molding (for example, two-color molding), the protector body can be easily manufactured at low cost.

According to the fourth aspect of the present invention, since the fixed portion slides back and forth to absorb the positional deviation of the mating side mounting portion and the distortion of the protector body due to the external force and heat, the protector body is not deformed. The wire harness is smoothly and surely accommodated in the protector body. By setting the slide amount to be large, it is possible to easily and surely attach regardless of the size of the positional deviation.

According to the fifth aspect of the present invention, the fixing portion rotates about the hinge to absorb the positional deviation of the mating mounting portion and the distortion of the protector body due to the external force or heat, so that the protector body is not deformed. It does not happen and the wire harness is stored smoothly and securely in the protector body. By making the fixing portion rotatable in the thickness direction of the protector body, for example, it is possible to easily and surely cope with a variation in the mounting position of the door panel or door trim in the automobile door in the thickness direction.

According to the sixth aspect of the invention, the fixing portion rotates in three dimensions around the ball joint to absorb the positional deviation of the mating mounting portion and the distortion of the protector body due to external force or heat. The wire harness is smoothly and reliably accommodated in the protector body without deformation of the protector body. In particular, when the fixing portion rotates in the three-dimensional direction, positional deviations and distortions in, for example, the front, rear, left and right, and upper and lower directions of the automobile door are absorbed, and the protector is more reliably prevented from deforming.

According to the seventh aspect of the present invention, since the protector body is smoothly accommodated in a bent state without being caught by the protector body in response to the swing of the wire harness due to the opening and closing of the slide door, It is possible to prevent the wire harness from being sandwiched between the vehicle body and the damage to the wire harness due to the pinching, and to improve the reliability of power supply from the vehicle body to each accessory in the slide door.
