Thus, the fog lamp 15 is attached to the central portion of the side opening 9 in the vehicle width direction with the lamp retainer 29 disposed in the lamp installation hole 23 and the lamp support portion 24.

  As described above, the front body design surface that protrudes from the front edge of the wheel house 4 of the left and right front wheels while being inclined toward the front of the vehicle is formed by the bumper fascia 3, and the left and right side parts 6 of the bumper fascia 3 are formed. The side opening 9 is formed in a region that can be viewed in front view and side view of the vehicle, and the side opening 9 is covered with the cover member 10, and the vehicle width direction outer portion of the cover member 10. 25, the reflector member 26 is attached in a state of being directed to the outside of the vehicle, so that the manufacturing cost can be kept low, and the reflector member 26 can be appropriately installed as necessary. There is an advantage that can be obtained.

  In other words, when the reflector member 26 is configured to be attached to the cover member 10 installed in the side opening 9 of the bumper facer 3, the attachment portion of the reflector member 26 is formed on the bumper facer 3. In addition, the shape of the bumper fascia 3 is changed between a destination of the vehicle where the reflector member 26 needs to be installed on the side of the vehicle body (for example, the United States) and a destination where it is not necessary to install the reflector member 26 (for example, within Japan). The reflector member 26 can be installed at an appropriate position as required. Therefore, it is possible to easily form a vehicle body front structure in which the reflector member 26 is installed so as to be visible from both the front and side surfaces of the vehicle while preventing the manufacturing cost of the vehicle from rising, and the reflector member. There is an advantage that the vehicle body front structure can be easily changed for a destination where the reflector member 26 does not need to be provided only by partially changing the shape of the cover member 10 if necessary and omitting 26. is there.

  Further, in the above embodiment, the laterally inclined surface formed by the left and right side portions 6 of the bumper fascia 3, in which the vehicle width direction outer portion 25 of the cover member 10 is located on the vehicle outer side than the side opening 9. The vehicle width direction outer portion 25 protrudes further to the front side of the vehicle than the left and right side portions 6 of the bumper fascia 3 while tilting so that the vehicle outer side is directed at a steeper angle than the vehicle width direction. Since the reflector member 26 is configured to be attached to the vehicle outer surface of the side portion 25, the reflector member 26 can have a sufficiently large area in a side view, and the visibility of the reflector member 26 can be effectively improved. There is an advantage that it is possible to effectively suppress the generation of a yawing moment that attempts to turn the vehicle body when the vehicle receives the power.

  That is, as shown in FIG. 13, when the traveling wind S blown obliquely on the front surface of the vehicle turns to the side of the vehicle along the bumper fascia 3, the vehicle width direction outer portion provided in the cover member 10. The turbulent flow R is generated by interfering with the front end portion 25 and the reflector member 26 attached to the outer surface thereof, and the traveling wind S is separated from the side surface of the vehicle body. It is possible to efficiently reduce the yawing moment caused by the negative traveling pressure that is about to turn. Therefore, there is an advantage that the running stability of the vehicle can be effectively improved with a simple configuration.

  The traveling wind S is separated from the side surface of the vehicle body due to the presence of the reflector member 26, and also generates a component T · U that detours above or below the reflector member 26 and flows to the rear of the side surface (FIG. 1). And the flow rate of the traveling wind S that peels from the side surface of the vehicle body is reduced. This causes a flow toward the outside of the vehicle by a collision between the wheel house 4 for the front wheel 4 and the tire or between the spokes of the wheel and the outside of the vehicle and the separated traveling wind S, which causes a flow toward the vehicle body side. Since it becomes a factor which enlarges the vortex R generated behind, it shows that the mechanism of deteriorating the traveling wind air resistance (Cd value) of the vehicle can be suppressed.

  Note that the cover member 10 covers a part of the side opening 9 excluding the installation area of the fog lamp 15 having a function as an auxiliary lamp of the headlamp, that is, the installation area of the lamp installation hole 23. Instead of the above-described embodiment, in the vehicle in which the fog lamp 15 is omitted, it is possible to cover the entire side opening 9 with the cover member 10.

  However, as shown in the above embodiment, an auxiliary lamp including a fog lamp 15 whose front surface is a lens surface is disposed in the frame of the side opening 9 formed in the bumper fascia 3, and the cover member 10 is provided with the auxiliary lamp. The lamp installation hole 23 that matches the lens surface is formed, and the outer portion 25 in the vehicle width direction of the cover member 10 is overlapped with the main body (lamp retainer 29) of the fog lamp 15 in a side view to conceal this. In this case, the fog lamp 15 that emits light toward the front of the vehicle and the reflector member 26 that includes the reflecting plate 30 that reflects light incident from the outside are collectively disposed in one place. By doing so, there is an advantage that the appearance of the front part of the vehicle body can be simplified and the beauty can be effectively improved.

  In particular, as shown in the above embodiment, the rear plate 31 of the reflector member 26 is provided with the holding portion 33 of the light emitting lamp 32, and the light emitting lamp 32 is disposed in the side opening 9 of the bumper fascia 3. In this case, by arranging the light-emitting lamp 32 in the vicinity of the fog lamp 15, it is possible to easily arrange the harnesses for the fog lamp 15 and the light-emitting lamp 32, and the light-emitting lamp 32 is turned on at night. As an advantage, the visibility of the reflector 30 can be effectively improved.

  The light emitting lamp 32 and its holding portion 33 may be omitted, and the reflector member 26 may be constituted by the reflecting plate 33 and the flat back plate 38 covering the back surface thereof as shown in FIGS. . In this case, there is no need to form the insertion hole 35 through which the holding portion 33 of the light-emitting lamp 32 is inserted in the outer portion 25 in the vehicle width direction of the cover main body 22. By making the cover member 10 common between the destination of the vehicle where the reflector member 26 needs to be installed (for example, the United States) and the destination where it is not necessary to install the reflector member 26 (for example, within Japan), the manufacturing cost is increased. There is an advantage that can be effectively reduced. In particular, as shown in FIG. 16, the structure of the cover member 10 is simplified by effectively reducing the manufacturing cost by adopting a structure in which the recess 34 for installing the reflector member 26 in the cover body 22 is omitted. can do.

  Moreover, in the said embodiment, the outer edge part 9b of the side opening part 9 formed in the bumper fascia 3 respond | corresponds to the front edge part 13 of the said wheel house 4 which stands | starts up diagonally back, curving in circular arc shape. Since the outer side edge 26a in the vehicle width direction of the reflector member 26 is installed along the outer edge portion 9b of the side opening 9, it is large without impairing the design of the front part of the vehicle body. There is an advantage that the reflector member 26 having an area can be installed in the side opening 9 to effectively ensure the visibility.
