2. Description of the Related Art A wire harness molded protector (hereinafter simply referred to as "molded protector") (see FIG. 6) is provided with a long groove protector body 2 which houses a wire harness 10 and which can be opened and closed via a thin hinge 4. Since the protector body 2 has the basic structure provided with the lid body 3, it is necessary to dispose the wire harness 10 in a narrow space.
It has a three-dimensional shape that matches the individual installation conditions of the installation site on the vehicle body / device. In addition, 20 in the figure is a lid body 3.
Is a lock portion of the lid body 3 that locks the tip of the and the other side wall 9B of the protector body 2.

Therefore, in the molded protector 1, when the common lid body 3 is provided on the protector body 2 which is bent in the biaxial direction, the hinge 4 has a uniaxial joint edge portion of the protector body 2 and the lid body 3. The other joint edge portion that intersects the hinge 4 biaxially is a hinge nonexisting portion 5 and there is a limitation that the lid 3 must be opened and closed.

However, if a vehicle having the hinge-free portion 5 is installed in the installation groove 18 on the floor of, for example, a car cabin, the passenger's foot covers the installation groove 18 on the carpet 17.
When pressing, the edge portion of the hinge nonexisting portion 5 of the lid body 3 is slightly forced into the inside of the one side wall 9A of the protector body 2, and when the foot is released, the other side is locked. The reaction force of the body 3 causes a phenomenon of rising up from the forced insertion state, which causes a "tick" noise. Therefore, as a measure for preventing the generation of the abnormal noise, as shown in FIG. 7, a configuration in which an abnormal noise prevention slit 16 is provided along the hinge non-existing portion 5 between the side wall 9A and the edge portion of the lid 3 is widely used. ing.

[0005]

If the molded protector 1 having the above-described conventional noise preventing slit 16 is installed in the installation groove 18 on the floor of the automobile cabin, the passenger's foot is installed in the installation groove 18. When the carpet 17 that covers the sheet is pressed, the lid 3 largely falls into the protector body 2 due to the pressing force, and the floor surface is recessed, and the function of protecting the wire harness 10 by the molded protector 1 is reduced, and the floor surface feels uncomfortable. Is caused, resulting in a decrease in riding comfort.

Further, when the pressed foot is released,
Since the lid body 3 in the recessed posture is restored upward by the elastic reaction force of the hinge 4, there is a risk of a defective phenomenon in which a part of the electric wire is placed on the lid body 3 and brought out of the molding protector 1 at the time of the restoration. In order to prevent the defective phenomenon, it is necessary to bind the wire harness 10 housed in the abnormal noise prevention slit 16 portion with a tape, which complicates the molding process of the wire harness 10 housed in the molding protector 1. It becomes a factor of high cost. The present invention provides a molding protector that solves the above-mentioned drawbacks of the prior art.
