As shown in FIG. 1, a pair of lamp housing fitting holes 2, 2 are formed at both sides of the bumper 1 of a car, with a number plate attaching section 3 being settled in the middle of said bumper 1, and each of said lamp housing fitting holes 2 has bottom panel 4 and ribs 5 and so on, as shown in FIG. 2, and a harness conducting hole 7 is formed in said bottom panel's 4 step section, being on the bumper center side.

The protector 8 of the present invention is shown in FIGS. 3 and 4. Said protector 8 consists of a hole inner side protective section 9 which is inserted into the inside of each lamp housing fitting hole 2 of said bumper 1, and a flange shaped surrounding protective section 10 formed at the outside of said hole inner side protective section 9, integrating with said hole inner side protective section 9. Further, a pair of sheets 11, 11 are attached to the inside of said hole inner side protective section 9 of said protector 8 to protect the inside of said lamp housing fitting hole 2 from the harness connected to said lamp housing.

Said protector 8 is preferably made of a thermoplastic synthetic resin having a Rockwell hardness of R50 to 150 according to ASTM D785. In a case where a thermoplastic synthetic resin having a Rockwell hardness of below R50 is used, the molded shape of the resulting protector 8 is not adequately held, while in a case where a thermoplastic synthetic resin having a Rockwell hardness of over R150 is used, the resulting protector 8 is difficult to deform, making it troublesome to take said protector 8 out of said lamp housing fitting hole 2, leaving said lamp housing 12 in said lamp housing fitting hole 2, as below described.

Said thermoplastic synthetic resin includes such as a high density polyethylene (R=50), polypropylene (homopolymer) (R=80˜102), polypropylene(copolymer) (R=65˜96), ABS (R=85˜106), polyamide6 (R=119), polyamide66 (R=120), polyamide46 (R=122), polyamidePA9T (R=118), polyethylene terephthalate (R=111), styrene modified-PPE (R=115˜116), AES (R=102˜109), AAS (R=96˜108), ACS (R=100˜107) and the like, and a polymer alloy of PPE-polyamide6-styrenic elastomer is a preferable thermoplastic resin in view of heat resistance, moldability, strength deformability, and the like.

An inorganic filler such as calcium carbonate, magnesium carbonate, barium sulphate, calcium sulphate, calcium sulfite, calcium phosphate, calcium hydroxide, magnesium hydroxide, aluminum hydroxide, magnesium oxide, titanium oxide, iron oxide, zinc oxide, alumina, silica, diaton earth, dolomite, gypsum, talc, clay, asbestos, mica, glass fiber, carbon fiber, calcium silicate, bentonite, white carbon, carbon black, iron powder, aluminum powder, stone powder, blast furnace slag, fly ash, cement, zirconia powder and the like, a natural fiber such as cotton, hemp, bamboo fiber, coconut fiber, wool silk and the like an organic synthetic fiber such as polyamide fiber, polyester fiber, acrylic fiber, viscose fiber, acetate fiber, vinyl chloride fiber, vinylidene chloride fiber, vinylon fiber, acetate fiber and the likes, an inorganic fiber such as asbestos fiber, glass fiber, carbon fiber, ceramic fiber, metallic fiber, whisker and the like, and an organic filler such as linter, linen, sisal, wood flour, coconut flour, walnut flour, starch, wheat flour and the like may be added to said thermoplastic synthetic resin. Further, a pigment, dye, antioxidant, antistatic agent, crystallization agent, flame retardant, antiflaming agent, insecticide, antiseptic, various waxes, a lubricant, age resister, ultraviolet absorber and the like may be added to said thermoplastic synthetic resin.

Said ingredient can be used singly or two or more kinds of said ingredient can be used together.

Said protector 8 is manufactured by such as vacuum forming, pressure forming, vacuum and pressure forming, press molding, stamping molding injection molding, or the like.

Said sheets 11, 11 are made of a soft type synthetic resin such as polyethylene, polypropylene, polyamide, polyester, polyurethane or the like, or a nonwoven fabric, knit, textile, or the like.

FIG. 5 shows a lamp housing 12 as a part. In said lamp housing 12, lamps 13, 14, 15, 16 and 17 are settled, with a harness 18 being connected to each lamp 13, 14, 15, 16 and 17 to supply electricity thereto.

To fit said lamp housing 12 into said lamp housing fitting hole 2 of said bumper 1, said protector 8 is first attached to said lamp housing fitting hole 2 as shown in FIGS. 7 and 8. As shown in FIGS. 7 and 8, in a case where said protector 8 is attached to said lamp housing fitting hole 2, said hole inner side protective section 9 of said protector 8 is inserted into said lamp housing fitting hole 2 to cover and protect the inside of said hole 2, and said surrounding protective section 10 of said protector 8 closely covers the outside of said surroundings of said hole 2 so as to protect the surroundings of said hole 2. Further, said sheets 11, 11 of said protector 8 each cover the inside of the part of said hole 2 through which said harness 18 passes.

As described above, said protector 8 is fit into said hole 2 of said bumper 1, after which said lamp housing 12 is inserted into said hole 2 over said protector 8 as shown in FIGS. 9 and 10. In this case, said protector 8 prevents the inside or surroundings of said hole 2 from being damaged by said lamp housing 12, harness 18, the hands of workers, tools, and the like.

After said lamp housing 12 is fit into said hole 2 over said protector 8, said protector 8 is taken out of said hole 2 as shown in FIG. 11. When said protector 8 is taken out of said hole 2, said protector 8 easily deforms since said protector 8 is made of a thermoplastic synthetic resin having a hardness of R50 to 150, making it easy to remove said protector 8 from said hole 2.
