A substantially square finisher 1a is integrally formed with the bumper facer 1 at a position where the fog lamp 3 as a lamp is to be attached, in a size corresponding to the fog lamp 3. As shown in FIG. 1, the front surface of the finisher 1a is shaped in harmony with the horizontal-based modeling of the peripheral portion, and has a structure that does not cause a sense of incongruity when the fog lamp 3 is not provided.

The upper, lower, left and right peripheries of the finisher 1a are bordered by deep grooves 1b and 1c, and the upper and lower deep grooves 1b extend substantially horizontally, as shown in FIG. 3 (a sectional view taken along line AA in FIG. 1). In addition, a thin portion 1d for break formed narrow at the bottom of the groove extends in the longitudinal direction of the groove 1b. A deep groove 1c as shown in FIG. 4 (a cross-sectional view taken along the line BB in FIG. 1) is provided on the left and right sides (the center and outside of the vehicle) of the finisher 1a.
Are provided to extend obliquely in the vertical direction along the inclination of the edge of the fog lamp 3 shown in FIG. 2, and a narrow slit 1e is formed at the bottom of the groove. Thus, the periphery of the finisher 1a is integrated with the bumper facer 1 at the thin portion 1d, and is not connected at the slit 1e.

More specifically, the slit 1e of the deep groove 1c on the left side (vehicle center side) in FIG. 4 is provided in the middle of the vertical extension while being bent in a Z-shape as shown in FIG. At the bottom of the groove at the upper left corner, a slit 1e forms a mounting seat 1g disconnected from the finisher 1a. As shown in the perspective view of FIG. 5, the shape of the mounting seat 1g is such that the front surface 1j of the lower end seat 1h has a low step with the step 1k as a boundary. A substantially triangular folded portion of the J nut 7 is inserted into the lower end seat portion 1h from below, and an upper edge thereof is brought into contact with the step portion 1k, and a female screw of the J nut 7 is provided in a mounting hole 1f provided in the mounting seat 1g. And can be positioned.

When the fog lamp 3 is provided,
A hole 1m for mounting the cover 9 is provided to close the mounting seat 1g and a space C (see FIG. 1) formed below the mounting seat.

Further, an insertion hole 1p as a supporting portion for supporting one side of the fog lamp 3 is provided in the outer peripheral groove wall of the right deep groove 1c in FIG. It is established in the place.

First, when the finisher 1a of the bumper facer 1 is cut, an opening having the size of the finisher 1a is formed. That is, when the thin portion 1d of the upper and lower deep grooves 1b of the finisher 1a is cut, the left and right deep grooves 1c are separated from the beginning by the slits 1e, so that the finisher 1a is separated from the bumper facer 1 and the finisher 1a An opening is formed in size.
In FIG. 2, this opening is designated by the same reference numeral 1 as the finisher for convenience.
This is indicated by a. Then, the J nut 7 is inserted into the lower end seat 1h from below until it comes into contact with the J nut 7. Thereafter, the fog lamp 3 is inserted into the opening 1a shown in FIG. 2 obliquely with its right side first in a substantially horizontal posture, and the projection 3p on one side of the fog lamp 3 is inserted into the insertion hole 1p of the bumper facer 1. Then, the bracket 3 on the other side of the fog lamp 3
g is mounted on the mounting seat 1g of the bumper fascia 1 with the bolt 5. In the mounted state of the fog lamp 3, the optical axis adjusting screw 3c provided on the other side is located in the space C below the mounting seat 1g. The optical axis is adjusted, and after the adjustment in the optical axis direction is completed, the space C including the mounting seat 1g is clipped to the bumper facer 1 with the cover 9 and closed.

Therefore, according to the present embodiment, when no fog lamp is provided, the finisher 1a remains integral with the bumper facer 1, so that an increase in the number of parts can be restricted. Thin part 1 above and below finisher 1a of bumper fascia 1
Since only d needs to be cut, the detachment operation of the finisher 1a is easy.

[0023]

As is apparent from the above description, according to the first aspect of the present invention, when the lamp is not provided, the finisher is formed integrally with the bumper facer at the lamp mounting portion of the bumper facer. Therefore, the bumper fascia may be left as it is, and the appearance can be ensured without specially equipped equipment, so that an increase in the number of parts can be suppressed, which is advantageous in cost.

On the other hand, when a lamp is provided, the finisher is cut at a thin portion and detached to form a lamp mounting opening. Therefore, a J-nut is mounted on a mounting seat from outside the bumper facer to support the lamp. The lamp can be easily mounted on the lamp and the mounting seat.

In the mounted state of the lamp, since the optical axis adjusting screw provided on the other side is located in the space below the mounting seat, the optical axis can be adjusted by the optical axis adjusting screw. Therefore, the operation can be easily performed from the outside of the bumper facer, including the mounting of the lamp and the adjustment of the optical axis.
