As shown in FIG. 3, a through hole 93 is provided in a portion of the bumper cover 92 where the exhaust pipe 90 is disposed. A tab 94 protrudes rearward from the periphery of the through hole 93 of the bumper cover 92. The vehicle garnish 1 is positioned with respect to the vehicle 9 by engaging the tab 94 with the slit 39a.

  As shown in FIG. 3, in order to fix the vehicle garnish 1 to the exhaust pipe 90, the opening rim 91 of the exhaust pipe 90 is inserted into the enclosed space 38 of the vehicle garnish 1. The plating layer 4 on the back surface 3 b of the inner peripheral portion 32 is adhered to the inner peripheral surface 91 a of the opening peripheral edge 91 of the exhaust pipe 90 using the heat resistant adhesive 7.

  In the present embodiment, the design surface 3a of the main body 3 has sharply bent surface portions 3d, 3g, and 3i having a curvature radius R of less than 3 mm. For this reason, compared with the garnish produced by metal processing, it will have a sharp shape and is good-looking. Further, whitening and wrinkles were not generated in the vicinity of the sharply bent surface portions 3d, 3g, and 3i, and the entire vehicle garnish 1 exhibited a beautiful metallic luster.

  Moreover, since the main-body part 3 consists of an injection molding product of a synthetic resin, workability is good. For this reason, the sharp garnish 1 for vehicles which was difficult by metal processing can be produced.

  The plating layer 4 that covers the back surface 3 b of the main body 3 reflects the exhaust heat from the exhaust pipe 90. For this reason, the transmission of exhaust heat to the bumper cover 92 can be reduced.

  As shown in FIGS. 7 and 8, the vehicle garnish 1 of this embodiment can be brought close to the decorative molding 5 provided on the bumper cover 92. The decorative molding 5 includes a molding main body 53 made of ABS resin and a molding plating layer 54 that covers the surface of the molding main body 53. The mole plating layer 54 is subjected to hexavalent chromium plating on the surface layer. A vehicular garnish 1 is disposed below the decorative molding 5. The clearance S between the decorative molding 5 and the vehicle garnish 1 is as narrow as 5 mm. Conventionally, the decorative molding 5 has a gap S of about 10 to 30 mm in order to avoid the influence of deformation due to exhaust heat. In this example, since the vehicular garnish 1 blocks the exhaust heat, the gap S can be reduced and the vehicular garnish 1 can be disposed close to the decorative molding 5. For this reason, it is preferable to arrange the garnish 1 for a vehicle between the exhaust pipe 90 and the decorative molding 5 closest to each other. Moreover, since the surface of the garnish 1 for a vehicle is covered with the same plating layer 4 as the decorative molding 5, a design with a sense of unity with the decorative molding 5 can be formed.

  The vehicular garnish 1 of this embodiment can also be provided on the opening periphery of the dummy exhaust pipe. As shown in FIG. 9, the dummy exhaust pipe is a through hole 93 formed in the bumper cover 92. There is no exhaust pipe behind the through hole 93. The real exhaust pipe 90, that is, the exhaust cylinder 95 connected to the muffler is disposed below the bumper cover 92. Note that a separate cover may be fitted to the vehicle garnish 1 of the through hole 93 to close the through hole 93.

  The vehicular garnish 1 of the present embodiment is a substantially parallelogram-shaped frame, but is not limited to a substantially parallelogram, and may have various frame shapes such as a triangle and a trapezoid. Moreover, the shape which covers at least one part of the opening periphery 91 of an exhaust pipe may be sufficient even if it is not a frame-shaped body.

  In the present embodiment, the sharply bent surface portions 3d and 3g having a radius of curvature R of less than 3 mm are provided on the design surface 3a of the inner bent portion 35 of the flange portion 31, but not limited to this, any portion of the design surface 3a Can also be provided. For example, the design surface 3a of the outer bent portion 36 of the flange portion 31 may be provided with sharp bent surface portions 3d and 3g, and a bent portion is provided at a portion other than the inner bent portion 35 or the outer bent portion 36 of the flange portion 31 and bent. The sharply bent surface portions 3d and 3g may be provided on the design surface 3a of the portion.

  In the present embodiment, the sharply bent surface portions 3d and 3g formed on the design surface 3a of the main body portion 3 have a bending angle of less than 180 °, and thus appear as continuous ridge lines protruding toward the front side. However, unlike the present embodiment, when the bending angle of the sharply bent surface portions 3d, 3g exceeds 180 °, the sharply bent surface portions 3d, 3g appear to be continuous valley lines that are recessed toward the back side. In any case, since the radius of curvature R of the sharply bent surface portions 3d and 3g is less than 3 mm, the ridge line or the valley line is clearly seen, and the vehicle garnish 1 is shown three-dimensionally.

  In the present embodiment, as shown in FIG. 2, the sharply bent surface portion 3 g bent in the plane direction M is formed in the inner bent portion 35, but may be formed in the outer bent portion 36. Further, a sharply bent surface portion 3g that bends in the plane direction M can be formed at the inner end portion 3t or the outer end portion 3u of the main body portion 3.
