And an insertion opening 6f which is continuous with the fitting opening 6e and extends in the vehicle width direction. The clip 12 is attached to the bulging portion 6d, and the engaging portion 1a of the headlamp 1 is attached to the clip 12. As shown in FIG. 1, the locking portion 1a is provided on the radiator grill side (central portion side) of the headlamp 1. The locking portion 1a includes left and right partition plates 1b and a bottom plate 1c, and a cutout 1d is provided in the bottom plate 1c. As shown in FIGS. 1 and 7, etc., the clip 12 has upper and lower holding plates 12b and 12c formed on the upper and lower sides of a square tubular body 12a, respectively. An upper insertion gap 12d into which the bottom plate 1c of the locking portion 1a is inserted is formed between the plate 12b and the body 12a, and the bulge is formed between the lower holding plate 12c and the body 12a. A lower insertion gap 12e into which the portion 6d is inserted is formed. In the upper insertion gap 12d, a rectangular mounting rib 12 inserted into the notch 1d of the locking portion 1a is provided.
f is formed, and the fitting portion 12 is formed in the lower insertion gap 12e.
g is formed. As shown in FIGS. 1 and 6 and the like, the fitting portion 12g is provided with a fitting opening 6 of the upper retainer 6.
It is formed in a zigzag shape with respect to the direction of insertion into e, and its zigzag width H4 is equal to the width H3 of the fitting opening 6e. The width H5 of the distal end of the fitting portion 12g is formed to be approximately half the width H3 of the fitting opening 6e. Furthermore, Van parfait Isher 7, which is mounted so as to cover the upper retainer 6, as shown in FIG. 1, the upper surface portion 7a, the upper retainer 6
Is formed with a mounting hole 7b which is clipped to the mounting hole 7b. As described above, the headlamp 1 has the upper retainer 6 attached to the radiator grille side via the clip 12 and the like, and the fender side has a front fender 2 and a radio core (not shown) with the front fender 2 as a reference. It can be attached to the upper. Next, the operation will be described. First, the head lamps 1 on both sides are attached to the front fender 2 and a radial core upper (not shown) with reference to the front fenders 2 on both sides. On the other hand, the upper retainer 6 before the vehicle is mounted
The clip 12 is attached. That is, the lower holding plate 12c of the clip 12 is inserted into the insertion opening 6f of the bulging portion 6d of the upper retainer 6, and at the same time, the fitting portion 12g is inserted into the fitting opening 6e. At this time, the fitting opening 6e
Is larger than the width H5 of the distal end of the fitting portion 12g, the distal end of the fitting portion 12g can be easily applied to the insertion opening of the fitting opening 6e (see FIG. 6A). Then, begin to insert the fitting portion 12g into the fitting opening 6e, the fitting portion 12
Although the first protrusion C1 of g (hereinafter referred to as "first protrusion C1") abuts on the side surface of the fitting opening 6e, the opposite side of the first convex portion C1 is the fitting opening 6e Since there is no contact with the side surface, a play (gap) is formed between the fitting portion 12g and the fitting opening 6e, and the fitting portion 12g is easily inserted into the fitting opening 6e. Further, when the fitting portion 12g is inserted into the fitting opening 6e, the second convex portion C2 (hereinafter, referred to as “second convex portion”) of the fitting portion 12g is formed on the side surface of the fitting opening 6e. The second protrusion C2 and the first protrusion C1 are in contact with each other and are sandwiched between both side surfaces of the fitting opening 6e (see FIG. 6B). 6e will be inserted without play. Thus, the clip 12 is mounted on the upper retainer 6. According to the clip 12 having such a configuration,
Since the fitting portion 12g is formed in a zigzag shape with respect to the direction of insertion into the fitting opening 6e, as described above,
The distal end of the fitting portion 12g is easily applied to the insertion opening of the fitting opening 6e, and is easily inserted into the fitting opening 6e. Further, when the fitting portion is inserted, since the first and second convex portions come into contact with the inner surface of the mounting hole, unlike the conventional surface contact,
Low sliding resistance and good workability. Further, the first convex portion C1 and the second convex portion C2 of the fitting portion 12g are sandwiched between both side surfaces of the fitting opening 6e, and the fitting portion 12g is inserted into the fitting opening 6e without play. Therefore, the mounting accuracy of the headlamp 1 locked to the clip 12 is improved. Since the fitting portion 12g is formed in a zigzag shape, the elasticity in the zigzag width direction is enhanced. Therefore, even if the zigzag width H4 of the fitting portion 12g is slightly larger than the width H3 of the fitting opening 6e, the protrusions C1 and C2 of the fitting portion 12g press against both side surfaces of the fitting opening 6e. while being elastically deformed, the fitting portion 12g is inserted into the fitting opening 6e. Thus, the fitting portion 12
g has a followability to both side surfaces of the fitting opening 6e. Therefore, without increasing the forming accuracy of the fitting portion 12g and the processing accuracy of the mounting hole, the fitting portion is not loose. 12g can be inserted into the fitting opening 6e. As a result, the manufacturing cost can be reduced by relaxing the dimensional accuracy. [0034] Thereafter, the clip 12 mounted on the upper retainer 6 engages with the engaging portion 1a of the headlamp 1 is mounted an upper retainer 6 in the headlamp 1. That is, the bottom plate 1c of the locking portion 1a is
Of the mounting rib 1 at the same time
Insert 2f into notch 1d. Thus, the upper retainer 6 is supported by the pair of headlamps 1. Thereafter, as shown in FIG. 3, the mounting piece 6a of the upper retainer 6 is attached to a bracket 8 fixed to the reinforce 5 with bolts 9 and nuts 10 so that the upper retainer 6 is attached. To support. [0036] Then, the clip stopped the van parfait Isher 7 in the upper retainer 6. As described above, the headlamp 1 is attached with the front fender 2 as a reference, and the upper retainer 6 is attached and positioned to the locking portion 1a of the headlamp 1 on the radiator grille side. 7 is mounted, the radiator grille end not shown in the van parfait Isher 7 is attached. In other words, fender side of the headlamp 1 is mounted a front fender 14 as a reference, and van parfait Isher 19 and the radiator grille ends attached relative to the radiator grille side of the headlamp 1. [0038] Thus, with the fender side and the front fender 2 of the headlamp 1 can be set to a predetermined positional relationship can be set and radiator grille side and the radiator grille end of the headlamp 1 in the predetermined positional relationship. Therefore, even if a molding or assembling error occurs in the upper retainer 6, the radiator grill, or the like, the gap on both sides of the headlamp 1 can be made the same without being affected by the error, and the appearance quality can be ensured. Can be. Further, since the mounting position P of the headlamp 1 with respect to the upper retainer 6 is at the position of the center of gravity of the upper retainer 6 as described above, even if a load acts on the upper retainer 6 from the headlamp 1, it is bent. without upper retainer 6 rotates that prevents the so-called fell. The clip of the present invention can of course be applied to a part other than the headlamp mounting part as long as it has a zigzag shape. As described above, according to the first aspect of the present invention, the fitting portion is formed in a zigzag shape in the direction of insertion into the mounting hole. Since the zigzag-shaped projections are formed so as to abut on two or more locations on the inner surface of the mounting hole, the projections abut on the inner surface of the mounting hole when the fitting portion is inserted. Unlike those that come into surface contact, the sliding resistance is small and workability is good. Further, since the fitting portion is formed in a zigzag shape, the elasticity in the zigzag width direction is enhanced, so that the zigzag width of the fitting portion is set at the inner surface of the mounting hole. Since it has a follow-up property, the molding accuracy of the fitting part,
Also, the fitting portion can be inserted into the mounting hole without play without increasing the processing accuracy of the mounting hole. As a result, the manufacturing cost can be reduced by relaxing the dimensional accuracy. [0044] Also, with the fender side and the front fender of the headlamp can be set to a predetermined positional relationship can be set and radiator grille side and the radiator grille end of the headlamp in a predetermined positional relationship. Therefore, even if a molding or assembling error occurs in the upper retainer or the radiator grill as in the conventional case, the gap on both sides of the headlamp can be made the same without being affected by this, and the appearance quality can be secured. It has the practically useful effect of being able to.
