Description

【Technical Field】 【0001】 The present invention relates to a vehicle front structure. 【Background Art】 【0002】 The exterior members at the front of a vehicle such as an automobile are composed of various parts. For example, Patent Document 1 discloses a front bumper including a bumper body, a grill, a garnish, and a bezel attached to the bumper body. 【Prior Art Documents】 【Patent Documents】 【0003】 【Patent Document 1】 Japanese Patent Application Laid-Open No. 2008-87615 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0004】 In Patent Document 1, engagement claws and engagement holes are provided in parts of the front bumper such as the bumper body, garnish, and bezel. These parts are assembled to each other by the engagement of the engagement claws and the engagement holes, whereby the front bumper is assembled. When assembling the parts, force is applied to each part. Also, resin parts are easily deformed. Therefore, when assembling the parts, the position of the engagement claw may be displaced with respect to the engagement hole due to deformation or displacement of the parts, and it may be difficult for the engagement claw to engage with the engagement hole. 【0005】 Therefore, an object of the present invention is to provide a vehicle front structure capable of improving the assemblability of parts of the exterior member. 【Means for Solving the Problems】 【0006】 One aspect of the present invention is a vehicle front structure comprising an exterior member disposed at the front of a vehicle. In this vehicle front structure, the exterior member comprises a front bumper, a bumper lower net attached to the front bumper from the rear of the vehicle so as to close a bumper opening that is opened in the front bumper, and a radiator grille that covers the upper part of the front bumper located above the bumper opening from the front of the vehicle. The lower edge of the upper part of the bumper and the upper edge of the bumper lower net are engaged with each other at an engaging portion. The front bumper has a movement-restricting rib provided on the front surface of the portion of the lower edge adjacent to the engaging portion, which protrudes toward the radiator grille. [Effects of the Invention] 【0007】 According to one aspect of the present invention, a vehicle front structure can be provided that can improve the ease of assembly between exterior components.

[Modes for carrying out the invention] 【0009】 Hereinafter, an embodiment of the vehicle front structure according to the present invention will be described with reference to the drawings. In the drawings, the direction of arrow Fr indicates the front in the longitudinal direction of the vehicle, and the direction of arrow U indicates the upper in the vertical direction of the vehicle. Arrow L indicates the left side in the vehicle width direction when the vehicle is viewed from the rear towards the front. In the following description, "front" and "rear" correspond to the front and rear in the longitudinal direction of the vehicle, respectively, and "up" and "down" correspond to the upper and lower in the vehicle vertical direction, respectively. "Left" and "right" correspond to the left and right in the vehicle width direction when the vehicle is viewed from the rear towards the front. 【0010】 As shown in Figure 1, the vehicle front structure 100 of this embodiment includes an exterior member 10 positioned at the front of a vehicle such as an automobile. The exterior member 10 extends in the vehicle width direction and the vehicle vertical direction, forming the exterior design surface of the vehicle. At the rear of the exterior member 10, a sensor bracket 20 supporting a sensor such as a millimeter-wave radar that monitors the driving environment in front of the vehicle, and a grille air guide (not shown) that guides outside air taken in through the exterior member 10 to a radiator (not shown) are positioned. The sensor bracket 20 and the grille air guide are connected to the exterior member 10 from the rear of the vehicle. 【0011】 As shown in Figures 1 and 2, the exterior member 10 includes a front bumper 1, a bumper lower net 2 attached to the front bumper 1 from the rear of the vehicle, and a radiator grille 3 attached to the front bumper 1 from the front of the vehicle. The exterior member 10 may further include decorative parts 4 attached to the radiator grille 3 from the front of the vehicle. Figure 2 shows the assembled state of the exterior member 10 with the bumper lower net 2 and radiator grille 3 attached to the front bumper 1. In Figure 2, the decorative parts 4 are omitted. 【0012】 As shown in Figure 3, the front bumper 1 extends in the width direction and vertical direction, and a large bumper opening 1a is provided in the center of the front bumper 1 in the width direction, penetrating the front bumper 1 in the longitudinal direction of the vehicle. In the illustrated example, the bumper opening 1a is a roughly rectangular shape that is long in the width direction when viewed from the front of the vehicle. The front bumper 1 has a bumper upper part 11 located above the bumper opening 1a, a bumper lower part 12 located below the bumper opening 1a, and a pair of bumper side parts 13 located to the left and right of the bumper opening 1a. In other words, the bumper opening 1a is surrounded by the lower edge 11a of the bumper upper part 11, the upper edge of the bumper lower part 12, and the inner edges in the width direction of the pair of bumper side parts 13. The front bumper 1 is, for example, a resin injection molded product, and the bumper upper part 11, the bumper lower part 12, and the pair of bumper side parts 13 are integrally formed. 【0013】 The upper bumper 11 extends in the vehicle width direction and vertically between the upper parts of a pair of bumper side sections 13. The outer edges (left and right edges) of the upper bumper 11 in the vehicle width direction are connected to the inner edges of the pair of bumper side sections 13 in the vehicle width direction. The lower bumper 12 extends continuously in the vehicle width direction across the entire width of the front bumper 1 below the pair of bumper side sections 13. The lower edges of the pair of bumper side sections 13 are connected to the upper edges of the lower bumper 12. Each of the pair of bumper side sections 13 curves towards the rear of the vehicle as it extends outward in the vehicle width direction, and a fog lamp (not shown) is mounted on each bumper side section 13. 【0014】 Incidentally, the front bumper 1 may be composed of a plurality of components. For example, a pair of side bumpers that constitute a pair of bumper side portions 13, a connecting portion that constitutes the bumper upper portion 11 and connects the pair of side bumpers in the vehicle width direction, and a lower bumper that constitutes the bumper lower portion 12 may be separate from each other. 【0015】 As shown in FIG. 2, the bumper lower net 2 is a resin member formed in a lattice shape, and a plurality of ventilation holes penetrating the bumper lower net 2 in the vehicle front-rear direction are formed. A plate attachment portion 21 for attaching a number plate (not shown) is provided at the center in the vehicle width direction of the bumper lower net 2. The bumper lower net 2 has an outer shape corresponding to the outer shape of the bumper opening 1a. In the illustrated example, the bumper lower net 2 is generally rectangular and long in the vehicle width direction when viewed from the front of the vehicle, and extends in the vehicle width direction and the up-down direction. The bumper lower net 2 is attached to the front bumper 1 from the rear of the vehicle so as to close the bumper opening 1a. Specifically, the upper edge portion 2a of the bumper lower net 2 is engaged with the lower edge portion 11a of the bumper upper portion 11 at the first engagement portion E1 (see FIGS. 4 to 6). Further, the lower edge portion, the left edge portion, and the right edge portion of the bumper lower net 2 are engaged with the upper edge portion of the bumper lower portion 12, the right edge portion of the left bumper side portion 13, and the left edge portion of the right bumper lower portion 12, respectively, at engagement portions not shown. 【0016】 The radiator grille 3 is a resin member in which a plurality of ventilation holes penetrating the radiator grille 3 in the vehicle front-rear direction are formed. The radiator grille 3 extends in the vehicle width direction and the vehicle up-down direction, and is attached to the upper bumper 11 from the vehicle front, covering the entire upper bumper 11 from the vehicle front. Specifically, the radiator grille 3 is engaged with the lower edge portion 11a of the upper bumper 11 at the second engagement portion E2 (see FIGS. 4 and 5), and is engaged with other portions of the upper bumper 11 at a plurality of engagement portions (not shown). Through the ventilation holes and the openings opened in the upper bumper 11, cooling air for a radiator (not shown) disposed behind the vehicle of the front bumper 1 is taken in. In a state where the radiator grille 3 is attached to the upper bumper 11, the rear surface 3a of the radiator grille 3 is disposed at an interval from the front surface of the upper bumper 11 toward the vehicle front. Further, the radiator grille 3 is engaged with the upper edge portion 2a of the bumper lower net 2 at the third engagement portion E3 (see FIGS. 4 and 5). 【0017】 FIGS. 4 and 5 show the first engagement portion E1, the second engagement portion E2, and the third engagement portion E3, and FIG. 6 shows the first engagement portion E1. As shown in FIG. 4, the first engagement portion E1, the second engagement portion E2, and the third engagement portion E3 are arranged at different positions from each other in the vehicle width direction. FIG. 5 is a cross-sectional view of the exterior member 10 along the B-B' line passing through the first engagement portion E1, the second engagement portion E2, and the third engagement portion E3 shown in FIG. 4. FIG. 6 is a cross-sectional view of the exterior member 10 along the A-A' line passing through the first engagement portion E1 shown in FIG. 2. The first engagement portion E1, the second engagement portion E2, and the third engagement portion E3 are each provided at a plurality of positions spaced apart in the vehicle width direction. 【0018】 With respect to the first engagement portion E1, the lower edge portion 11a of the bumper upper portion 11 and the upper edge portion 2a of the bumper lower net 2 each extend in the vehicle width direction, and the upper edge portion 2a overlaps the lower edge portion 11a from the rear of the vehicle in the vehicle longitudinal direction, and the upper edge portion 2a and the lower edge portion 11a are engaged with each other at the first engagement portion E1. Specifically, the first engagement portion E1 has a first engagement claw E1a provided on the lower edge portion 11a and a first engagement hole E1b formed in the upper edge portion 2a. The first engagement claw E1a has a predetermined width in the vehicle width direction and protrudes toward the rear of the vehicle. The first engagement hole E1b has a width corresponding to the width of the first engagement claw E1a in the vehicle width direction and penetrates the upper edge portion 2a in the vehicle longitudinal direction. The first engagement claw E1a is configured to be inserted into the first engagement hole E1b from the front of the vehicle and engage with the first engagement hole E1b. In the illustrated example, the first engaging claw E1a has a wedge-shaped cross-section that thins towards the tip (rear end) and has a tip portion (rear end) that extends in the vehicle width direction. The first engaging claw E1a engages with the first engaging hole E1b when the tip portion passes through the first engaging hole E1b. The first engaging portion E1 is provided on both outer portions (left portion and right portion) in the vehicle width direction of the lower edge portion 11a, and Figures 4 and 5 show the left first engaging portion E1 and the second engaging portion E2 and third engaging portion E3 around it. In this embodiment, the first engaging portion E1 corresponds to the "engaging portion" according to the present invention, the first engaging claw E1a corresponds to the "engaging claw" according to the present invention, and the first engaging hole E1b corresponds to the "engaging hole" according to the present invention. 【0019】 Regarding the second engagement portion E2, the radiator grille 3 is superimposed on the lower edge portion 11a of the upper bumper portion 11 from the front of the vehicle in the longitudinal direction, and the radiator grille 3 and the lower edge portion 11a are engaged with each other at the second engagement portion E2. Specifically, the second engagement portion E2 has a second engagement claw E2a provided on the radiator grille 3 and a second engagement hole E2b formed in the lower edge portion 11a. The second engagement claw E2a has a predetermined width in the vehicle width direction and protrudes toward the rear of the vehicle. The second engagement hole E2b penetrates the lower edge portion 11a in the longitudinal direction of the vehicle. The second engagement claw E2a is configured to be inserted into the second engagement hole E2b from the front of the vehicle and engage with the second engagement hole E2b. 【0020】 Regarding the third engagement portion E3, the radiator grille 3 is superimposed on the upper edge portion 2a of the bumper lower net 2 from the front of the vehicle in the longitudinal direction, and the radiator grille 3 and the upper edge portion 2a are engaged with each other at the third engagement portion E3. Specifically, the third engagement portion E3 has a third engagement claw E3a provided on the radiator grille 3 and a third engagement hole E3b formed in the upper edge portion 2a. The third engagement claw E3a has a predetermined width in the vehicle width direction and protrudes toward the rear of the vehicle. The third engagement hole E3b penetrates the upper edge portion 2a in the longitudinal direction of the vehicle. The third engagement claw E3a is configured to be inserted into the third engagement hole E3b from the front of the vehicle and engage with the third engagement hole E3b. 【0021】 As shown in Figures 5 to 7, in this embodiment, the front bumper 1 (specifically, the upper part of the bumper 11) has a movement restricting rib 14 that restricts the forward movement of the lower edge 11a relative to the radiator grille 3. Figure 7 is an enlarged view of region C in Figure 3, including the first engaging claw E1a of the left first engaging portion E1 and the adjacent movement restricting rib 14. The movement restricting rib 14 is provided on the front surface 11a1 of the lower edge 11a adjacent to the first engaging portion E1 (in other words, around the first engaging portion E1) and protrudes toward the radiator grille 3 (i.e., toward the front of the vehicle). The front surface 11a is the front side of the lower edge 11a and faces the rear surface 3a of the radiator grille 3 in the longitudinal direction of the vehicle. In the illustrated example, the movement restricting rib 14 is provided at the same position as the first engaging portion E1 (specifically, the first engaging claw E1a) in the vehicle width direction, and is adjacent to the vehicle upper side of the first engaging portion E1 (specifically, the vehicle upper side of the base end of the first engaging claw E1a). 【0022】 The presence of such a movement-restricting rib 14 narrows the gap in the vehicle's longitudinal direction between the portion of the lower edge 11a adjacent to the first engaging portion E1 and the radiator grille 3. When the first engaging claw E1a is pushed forward, the movement-restricting rib 14 contacts the rear surface 3a of the radiator grille 3, restricting the forward movement of the first engaging claw E1a. A movement-restricting rib 14 is also provided for the right-side first engaging claw E1a (see Figure 1). The right-side movement-restricting rib 14 has the same structure as the left-side movement-restricting rib 14, except that it is symmetrical with respect to the left-right direction. 【0023】 As shown in Figures 5 and 6, in the assembled state of the exterior member 1 (finished vehicle), the movement restricting rib 14 is positioned with a gap between it and the rear surface 3a of the radiator grille 3 towards the rear of the vehicle. This suppresses the generation of rattle noise (contact noise between parts) caused by vibrations during vehicle operation. 【0024】 Figures 6 and 8 to 9B show the exterior members 10 in the process of assembling the bumper lower net 2 to the front bumper 1, and the exterior members 10 (1, 2, 3) are arranged so that the front of the vehicle faces vertically downward. In Figures 6 and 8 to 9B, the up and down direction of the figure corresponds to the vertical direction (direction of gravity), the left and right direction of the figure corresponds to the up and down direction of the vehicle, the bottom of the figure corresponds to the vertically downward side and the front of the vehicle, and the left side of the figure corresponds to the top of the vehicle. 【0025】 Figure 8 illustrates the assembly process of the exterior component 10. During the assembly process, the radiator grille 3 is assembled to the front bumper 1 from the front of the vehicle, thereby forming a unit of the front bumper 1 and the radiator grille 3. This unit is placed on a stand (not shown) with its design surface (front) facing vertically downward. In this state, the first engaging claw E1a protrudes vertically upward. Next, the bumper lower net 2 is assembled to the front bumper 1 of the unit from vertically above. Specifically, the first engaging hole E1b is aligned with the first engaging claw E1a, and then, as the bumper lower net 2 descends, the first engaging claw E1a is inserted into the first engaging hole E1b and engages with the engaging hole E1b. 【0026】 Here, when the first engaging claw E1a engages with the first engaging hole E1b, the first engaging claw E1a is pushed vertically downward by the bumper lower net 2, corresponding to the front of the vehicle. According to the vehicle front structure 100 of this embodiment, a movement restricting rib 14 is provided on the front surface 11a1 of the lower edge portion 11a adjacent to the first engaging portion E1, and the movement restricting rib 14 abuts against the rear surface 3a of the radiator grille 3, thereby restricting the movement of the first engaging claw E1a toward the front of the vehicle. As a result, even if the first engaging claw E1a is pushed downward by the vehicle during engagement, the displacement of the first engaging claw E1a and the resulting misalignment with respect to the first engaging hole E1b can be suppressed, and the first engaging claw E1a can be easily engaged with the first engaging hole E1b. 【0027】 Figures 9A and 9B illustrate the assembly process of an exterior component equipped with a comparative example front bumper 1' that does not have a movement-restricting rib 14. Figure 9A shows the bumper lower net 2 before lowering, and Figure 9B shows the bumper lower net 2 after lowering. When the bumper lower net 2 is lowered from the position shown in Figure 9A, the engaging claw E1a is pushed vertically downward by the bumper lower net 2, causing the engaging claw E1a and its surrounding area to be displaced vertically downward and deformed, resulting in a misalignment of the engaging claw E1a with respect to the engaging hole E1b. In this case, it is difficult to engage the engaging claw E1a with the engaging hole E1b. 【0028】 Furthermore, once the first engaging claw E1a is engaged with the first engaging hole E1b, the movement of the first engaging claw E1a in the direction of disengaging from the first engaging hole E1b is restricted by the movement restricting rib 14. Therefore, even if the upper part of the bumper 11 is pushed vertically downward when, for example, the sensor bracket 20 or the grille air guide is installed, it is possible to prevent the first engaging claw E1a from disengaging from the first engaging hole E1b and maintain the engagement between the first engaging claw E1a and the first engaging hole E1b. 【0029】 During the assembly process, the sensor bracket 20 is assembled to the unit from vertically above at the same time as, or before or after, the assembly of the bumper lower net 2 to the front bumper 1. After the assembly of the bumper lower net 2 and the sensor bracket 20 to the unit, the grille air guide (not shown) is assembled to the front bumper 1, bumper lower net 2, and sensor bracket 20 from vertically above. 【0030】 In this way, the ease of assembly between the front bumper 1 and the bumper lower net 2, which are components of the exterior member 10, can be improved. 【0031】 Next, the vehicle front structure 100 of the present invention will be described in detail. In this embodiment, the movement restricting rib 14 includes a plurality of longitudinal ribs 14a. Each of the plurality of longitudinal ribs 14a extends continuously in the vertical direction and protrudes forward from the front surface 11a1 of the vehicle, and is arranged with a gap between them in the vehicle width direction. Furthermore, the plurality of longitudinal ribs 14a are arranged between the vehicle width direction ends of the first engaging claw E1a in the vehicle width direction. In other words, the plurality of longitudinal ribs 14a are provided on the front surface 11a1 of the lower edge portion 11a in the vehicle width direction portion where the first engaging claw E1a is provided. 【0032】 In the illustrated example, the movement restricting rib 14 includes three longitudinal ribs 14a. The number of longitudinal ribs 14a may be two or four or more. The first engaging claw E1a protrudes rearward from the lower end of the lower edge portion 11a. Each longitudinal rib 14a extends upward from the lower end of the lower edge portion 11a so as to be continuous with the base end (front end) of the first engaging claw E1a, and the lower end of each longitudinal rib 14a is connected to the base end (front end) of the first engaging claw E1a. 【0033】 With this structure, the vertical ribs 14a extending in the vertical direction increase the bending rigidity of the lower edge portion 11a in the vehicle's longitudinal direction, and when the lower bumper net 2 is assembled to the front bumper 1, bending of the lower edge portion 11a vertically downward (forward of the vehicle) is more reliably suppressed. As a result, the displacement of the first engaging claw E1a is more reliably suppressed, and the ease of assembling the bumper lower net 2 to the front bumper 1 can be further improved. Furthermore, since the multiple vertical ribs 14a are arranged between the vehicle width direction ends of the first engaging claw E1a, the rigidity of the vehicle width direction portion of the lower edge portion 11a where the first engaging claw E1a is provided is effectively increased. As a result, unintended deformation and displacement of the first engaging claw E1a due to the load applied from the bumper lower net 2 during engagement can be more reliably suppressed. 【0034】 As shown in Figure 7, in this embodiment, the upper part of the bumper 11 further has a recess 15 located above the first engaging claw E1a on the vehicle and recessed toward the rear of the vehicle. The recess 15 is located at a distance above the first engaging claw E1a on the vehicle and is recessed toward the rear of the vehicle from the front surface 11a1 of the lower edge 11a. At least one of the multiple longitudinal ribs 14a extends upward to the recess 15 on the vehicle. 【0035】 In the illustrated example, the outer portion (left and right portion) of the lower edge 11a in the vehicle width direction, where the first engaging claw E1a is provided, bulges forward of the vehicle. The recess 15 is recessed towards the rear and below the vehicle and is open to the top and front of the vehicle. Of the three longitudinal ribs 14a, the two outer longitudinal ribs 14a in the vehicle width direction are positioned vertically between the first engaging claw E1a and the recess 15, extending upward to the lower edge of the opening edge of the recess 15 and continuing with the recess 15. 【0036】 The recessed area 15, which has a three-dimensional shape that is recessed towards the rear of the vehicle, has increased rigidity. By having at least one longitudinal rib 14a continuous with this recessed area 15, the rigidity of the portion of the lower edge 11a adjacent to the engaging claw E1a is further increased, making it possible to more reliably suppress deformation such as bending of the engaging claw E1a and its surrounding area when the bumper lower net 2 is assembled to the front bumper 1. 【0037】 As shown in Figure 10, in a configuration having a recess 15, the upper bumper 11 may further have a reinforcing rib 16 provided between the first engaging claw E1a and the recess 15 on the rear surface 11a2 of the lower edge 11a, and projecting rearward from the rear surface 11a2 of the vehicle. The rear surface 11a2 is the rear side of the lower edge 11a (in other words, the side opposite to the front surface 11a1). The reinforcing rib 16 extends in the vertical direction of the vehicle from the first engaging claw E1a to the recess 15, the lower end of the reinforcing rib 16 is connected to the base end (front end) of the first engaging claw E1a, and the upper end of the reinforcing rib 16 is connected to the lower wall of the recess 15. Furthermore, the reinforcing rib 16 is positioned in a region that overlaps with the region where the movement restricting rib 14 is provided in the longitudinal direction of the vehicle when viewed from the front of the vehicle. In the illustrated example, the reinforcing rib 16 extends upward from the center in the vehicle width direction of the base end (front end) of the first engaging claw E1a, and is positioned to roughly overlap with the middle longitudinal rib 14a when viewed from the front of the vehicle. 【0038】 In this way, the addition of the reinforcing rib 16 further increases the rigidity of the portion of the lower edge 11a adjacent to the first engaging claw E1a. Therefore, deformation such as curvature of the first engaging claw E1a and its surrounding area during assembly of the bumper lower net 2 to the front bumper 1 can be suppressed even more reliably. 【0039】 As shown in Figure 8, in this embodiment, the bumper lower net 2 has a guide inclined wall 22 for guiding the first engaging claw E1a to the first engaging hole E1b when the bumper lower net 2 is assembled to the front bumper 1. The guide inclined wall 22 extends continuously from the upper edge of the periphery of the first engaging hole E1b toward the front of the vehicle and is inclined toward the vehicle toward the front of the vehicle. 【0040】 In the illustrated example, the bumper lower net 2 has a protruding piece 23 that projects outward from the upper edge of the periphery of the first engagement hole E1b and abuts against the tip of the first engagement claw E1a that has passed through the first engagement hole E1b from above the vehicle. The guide inclined wall 22 extends from the base end (front end) of the protruding piece 23, inclined upward from the vehicle as it moves forward, and the rear part of the guide inclined wall 22 defines the upper edge of the first engagement hole E1b. 【0041】 As the bumper lower net 2 descends, inserting the first engaging claw E1a into the first engaging hole E1b, the tip (rear end) of the first engaging claw E1a contacts the lower surface (or front surface) of the guide inclined wall 22 that faces diagonally downwards and forwards. Subsequently, the bumper lower net 2 descends while moving upwards and toward the vehicle in accordance with the inclination of the guide inclined wall 22 (moving diagonally downwards and to the left in Figure 8), so that the tip of the first engaging claw E1a slides along the lower surface (or front surface) of the guide inclined wall 22 toward the first engaging hole E1b. When the tip (rear end) of the first engaging claw E1a reaches the first engaging hole E1b, the bumper lower net 2 descends vertically so that the first engaging claw E1a is inserted into the first engaging hole E1b. 【0042】 In this way, as the bumper lower net 2 descends, the first engaging claw E1a is guided to the first engaging hole E1b according to the inclination of the guide inclined wall 22. This allows the first engaging claw E1a to be easily and reliably inserted into the first engaging hole E1b, further improving the ease of assembling the bumper lower net 2 to the front bumper 1. 【0043】 As shown in Figures 6 and 8, the exterior member 10 further includes a lower restricting wall 24 and an upper restricting wall 31 to prevent the bumper lower net 2 from moving too far upward when it is assembled to the front bumper 1. Specifically, the bumper lower net 2 has a lower restricting wall 24 that is spaced below the first engagement hole E1b and extends forward of the vehicle, and the radiator grille 3 has an upper restricting wall 31 that is positioned adjacent to the upper side of the lower restricting wall 24 and extends rearward of the vehicle (in the assembled state of the exterior member 10). 【0044】 In the illustrated example, the bumper lower net 2 has a vertical wall 2a1 that extends in the vehicle's vertical and vehicle width directions and forms an upper edge portion 2a, and a horizontal wall 2a2 that is connected to the lower end of the vertical wall 2a1 and extends in the vehicle's longitudinal and vehicle width directions. The first engagement hole E1b is formed in the vertical wall 2a1. The horizontal wall 2a2 extends forward of the vehicle beyond the vertical wall 2a1, and the lower regulating wall 24 is composed of the front end portion of the horizontal wall 2a2 that protrudes forward of the vehicle relative to the vertical wall 2a1. The lower regulating wall 24 is positioned below the guide inclined wall 22 at a distance from the vehicle and faces the guide inclined wall 22 in the vehicle's vertical direction. The upper regulating wall 31 is a flange-like portion formed by bending the lower edge portion of the radiator grille 3 toward the rear of the vehicle. In the assembled state of the exterior member 10 (finished vehicle), the lower regulating wall 24 and the upper regulating wall 31 face each other at least partially in the vehicle's longitudinal direction. 【0045】 With this structure, when the bumper lower net 2 is assembled to the front bumper 1, the lower restricting wall 24 contacts the upper restricting wall 31 from below the vehicle, thereby restricting (preventing) any further upward movement of the bumper lower net 2. This prevents the bumper lower net 2 from moving too far upward during assembly, further improving the ease of assembly of the bumper lower net 2 to the front bumper 1. 【0046】 As shown in Figure 8, it is preferable that the first distance X1 is equal to the second distance X2 so that there is a gap of appropriate size between the lower regulating wall 24 and the upper regulating wall 31 in the assembled state (finished vehicle). The first distance X1 is the distance in the vehicle's vertical direction between the upper surface of the lower regulating wall 24 and the lower edge of the periphery of the first engagement hole E1b. The second distance X2 is the distance in the vehicle's vertical direction between the vehicle's vertical center of the rear end surface (tip surface) of the engagement claw E1a and the lower surface of the upper regulating wall 31. 【0047】 With this structure, the engagement of the first engagement claw E1a with the first engagement hole E1b positions the upper regulating wall 31 at a location where an appropriate predetermined gap in the vehicle's vertical direction is created between the upper surface of the lower regulating wall 24 and the lower surface of the upper regulating wall 31. This improves the assembly accuracy of the bumper lower net 2 to the front bumper 1. 【0048】 Although embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above, and further modifications and changes are possible based on the technical concept of the present invention. 【0049】 For example, in the above-described embodiment, the movement restricting rib 14 includes a plurality of longitudinal ribs 14a extending in the vertical direction of the vehicle, but the specific form of the movement restricting rib 14 is not limited thereto. For example, the movement restricting rib 14 may have ribs of a different shape from the longitudinal ribs 14a. Also, in the above-described embodiment, the movement restricting rib 14 is provided at a position adjacent to the upper side of the first engaging portion E1, but the position of the movement restricting rib 14 relative to the first engaging portion E1 is not limited thereto, and it may be provided at other positions on the lower edge portion 11a adjacent to the first engaging portion E1. Also, in the above-described embodiment, one reinforcing rib 16 is provided on the rear surface 11a2, but two or more reinforcing ribs 16 may be provided. [Explanation of Symbols] 【0050】 1.
