[0022]

As is apparent from the above description, in the wire harness protector according to the first aspect, the slide plate portion of the lid is fitted onto the guide plate portion of the protector body, and the lid is attached to the protector body. Since the upper opening of the protector body is closed by sliding it along the vertical direction, even if the wire is inserted into the protector body in a state of being raised from the upper opening, the wire slides on the protector as the lid slides. It is pushed into the main body and the lid can be closed smoothly.

Similarly, when the electric wire extends laterally from the upper opening, the protruding electric wire is moved to the center of the protector body as the lid slides.
The electric wire does not get caught between the lid and the protector body,
The lid can be attached to the protector body.

Further, in the state where the lid is attached to the protector body, stress is applied to the entire guide plate portion of the protector body and the slide plate portion of the lid when the protector for the wire harness is transported, so that the above guide plate portion is applied. Also, the slide plate portion will not be damaged and the lid will not come off from the protector body. Further, unlike the conventional protector for wire harness, it is not necessary to form a plurality of lock claws and lock portions, so that the work of attaching the lid to the protector body is easy, and the protector body and the molding die for the lid are simplified. Therefore, the manufacturing cost can be reduced.

In the wire harness protector according to the second aspect of the present invention, since the auxiliary rib protruding from the lid is connected to the tensioner, the number of wire harnesses substantially equal to the capacity of the protector body is inserted. Therefore, even if the wire harness comes into contact with the lid, the lid can be easily slid. In this way, since the work of sliding the lid is performed by the tensioner, the work efficiency can be maintained for a long time while maintaining high work efficiency.
