  A flange 49 extending toward the center of the vehicle is provided at the end of the front bumper 15 on the fender panel 23 side. The flange 49 is provided between the rib 48 of the holder body 29a and the stepped portion of the fender panel 23. The front bumper 15 is engaged and held by engaging the hole 49a provided in the flange 49 with the holder claw 48a formed on the rib 48.

  On the other hand, as shown in FIG. 6, a pin 34 protruding downward is provided at the bottom of the headlamp 24, and a flange 35 is formed at the tip of the pin 34.

  As shown in FIG. 5, the headlamp fixing portion 29b of the holder 29 has a horizontal surface 36 provided at the upper end of the holder main body 29a. The horizontal surface 36 extends to the inside of the vehicle in a state where the holder 29 is fixed to the holder mounting portion 28 of the fender panel 23.

  On the horizontal surface 36, a pin engaging portion 37 that can engage the pin 34 of the headlamp 24 is provided. Specifically, on the horizontal plane 36, a bag-like ridge portion receiving portion 37a that opens at the front side and into which the ridge portion 35 at the tip of the pin 34 of the headlamp 24 enters is formed. A pin engaging hole 37b that opens on the upper side is formed on the upper surface. The relative position in the vertical direction is regulated by the engagement of the collar part 35 and the collar part accommodating part 37a, and the relative position on the horizontal plane is regulated by the engagement of the pin 34 and the pin engagement hole 37b. Furthermore, a guide portion 37c that is connected to the opening of the pin engagement hole 37b and gradually widens in a V shape toward the front is formed. A stopper 38 that restricts the headlamp 24 from moving to the back side is provided on the horizontal plane 36 behind the pin engaging portion 37.

  In the vehicle 10 having the configuration described above, with the holder 29 fixed to the holder mounting portion 28 of the fender panel 23, the holder claw 48a of the holder 29 (holder body 29a) is attached to the flange 49 of the front bumper 15 as described above. While engaging with the hole 49a, the clip 51 is fitted into the bottom hole of the holder 29 (holder body 29a) and the fitting hole of the bracket 33 of the front bumper 15.

  Thus, the end portion of the front bumper 15 is engaged and held, and the position of the end portion of the front bumper 15 with respect to the fender panel 23 is determined. Accordingly, it is possible to eliminate the protrusion difference (step) in the vehicle width direction between the front bumper 15 and the fender panel 23, and it is possible to make the gap between the front bumper 15 and the fender panel 23 as set.

  The front bumper 15 configured as described above is fixed to the bumper support portion (reinforce) 27 and the bumper bracket at other portions by a fixing tool (screw).

  On the other hand, with the holder 29 fixed to the holder mounting portion 28 of the fender panel 23, the pin 34 of the headlamp 24 is engaged with the pin engaging portion 37 of the holder 29 (headlamp fixing portion 29b) as described above. .

  That is, as shown in FIG. 4, the headlamp mounting portion 39 is formed so as to be surrounded by the fender panel 23 and the front bumper 15, but the headlamp fixing portion 29 b of the holder 29 is just inside the headlamp mounting portion 39. It is located below. In this state, after the pin 34 of the headlamp 24 is positioned in the V-shaped guide portion 37c and then the headlamp 24 is pushed in, as shown in FIG. 5, the collar portion 35 is moved into the collar portion accommodating portion 37a. The pin 24 is received and engaged with the pin engaging hole 37b. In this way, the pin 34 is initially positioned in the guide portion 37c spreading in a V shape, and then the headlamp 24 is pushed in, so that the assembling property can be improved.

  When the headlamp 24 is engaged and positioned with the holder 29, the position of the headlamp 24 (particularly the lower part) with respect to the fender panel 23 is determined by the holder 29, and the position with respect to the front bumper 15 is determined by the holder 29. become. In this case, since the flange part 25 at the tip of the pin 34 is accommodated in the collar part accommodating part 37a, the vertical movement of the headlamp 24 is also restricted, and the headlamp 24 is reliably Positioning is possible.

  The headlamp 24 thus configured is fixed at three locations with respect to the vehicle body side. Two brackets 40 and 41 are projected from the upper portion of the headlamp 24, the bracket 40 is fixed to the fender panel 23 by a fixture (clip) 42, and the bracket 41 is fixed to the member 43 ( Screw) 44. A bracket 45 projects from the side of the headlamp 24 and is fixed to the bracket of the dash panel 25 by a fixture (screw) 46. In this manner, the upper portion of the headlamp 24 is also assembled to the fender panel 23, whereby the headlamp 24 is positioned relative to the fender panel 23 above and below the headlamp 24. As a result, the gap between the headlamp 24 and the fender panel 23 can be made uniform across the top and bottom.

  According to the vehicle front structure described above, since the front bumper 15 and the headlamp 24 are assembled to the holder 29 fixed to the fender panel 23, the fender panel 23, the front bumper 15, and the headlamp 24 are mutually connected. Positioning is done. Thereby, it is possible to prevent variation in the gap size (parting size) where these parts are connected, and to improve the appearance (commercial property).

  In particular, in the vehicle according to the present embodiment, as shown in FIG. 1, the headlamp 24 and the front bumper 15 are disposed close to the upper side and the lower side of the fender panel 23. The parting line α between the front bumper 15 and the fender panel 23 is continuous in a straight line, and if there is a difference in the gap between the parting parts, it becomes very noticeable. Can be prevented.

  Further, if the lower part of the headlamp 24 is to be fixed with a fixing tool such as a screw, the work must be performed on the back side of the front bumper 15. As described above, the lower part of the headlamp 24 is engaged with the holder 29. Since it has a structure, it is possible to improve assemblability. In addition, since the headlamp 24 has a simple structure in which only the pins 34 are projected and a relatively complicated engagement structure is formed on the holder 29 side, productivity can be improved.

(Second Embodiment)
In the second embodiment, the configuration of the pin engaging portion 37 of the holder 29 is changed. Hereinafter, the second embodiment will be described with reference to FIG. 7. The difference from the first embodiment will be mainly described, and the same components as those already described are denoted by the same reference numerals. Detailed description thereof will be omitted.

In the first embodiment, as shown in FIG. 5, the opening of the pin engagement hole 37b faces the front side, and the assembly direction of the pin 34 to the pin engagement hole 37b (arrow X _{1 in} FIG. 5) is the vehicle. It overlaps with the direction of travel.

  However, the direction in which the external force acts on the pin 34 substantially coincides with the traveling direction of the vehicle. For example, when the headlamp 24 is fixed at the upper part and one side part as described above, it vibrates around the line connecting the fixed parts as the center of rotation, and the pin 34 moves away from the opening of the pin engagement hole 37b. External force will act.

  In order to prevent the pin 34 from being detached from the pin engagement hole 37b due to vibration, it is conceivable to tighten the engagement of the pin 34 to the pin engagement hole 37b, but this deteriorates the assembling property.

Therefore, in this embodiment, as shown in FIG. 7, the pin 34 is assembled to the pin engagement hole 37b with the opening of the pin engagement hole 37b facing forward (45 degrees with respect to the traveling direction of the vehicle). The direction (arrow X _{2 in} FIG. 7) is shifted from the traveling direction of the vehicle. Specifically, the opening position of the pin engagement hole 37b is shifted with respect to the vibration direction of the headlamp 24 with the line connecting the upper portion of the headlamp 24 and the fixed portion on one side as the rotation center, Since the opening position is provided obliquely outward of the vehicle, it is possible to avoid the problem of interference with other parts when the headlamp 24 is assembled.

  As a result, even if an external force is applied in the traveling direction of the vehicle, the pin 34 is removed from the opening of the pin engagement hole 37b, and the problem that the headlamp 24 rattles is eliminated. Further, it is not necessary to tightly engage the pin 34 with the pin engaging hole 37b, and it is possible to prevent the assembling performance from being impaired.

  As mentioned above, although this invention was demonstrated with various embodiment, this invention is not limited only to these embodiment, A change etc. are possible within the scope of the present invention.

  The vehicle front structure described above can also be applied to a vehicle rear structure (rear bumper and rear combination lamp mounting structure).
