An engaged portion 31 formed corresponding to the joint portion 28 is formed. The locking hole 29 is formed as a rectangular hole through which the guide protrusion 30 can be inserted and the claw can be elastically engaged. On the other hand, the engaged portion 31 is set in a range from the base portion of the lower end portion 16B of the first support portion 16 to a later-described shelf portion 42 formed adjacent to the base portion. The engaged portion 31 is formed with a fitting portion 32 into which the engaging portion 28 is fitted. By fitting the engaging portion 28 into the fitting portion 32, the fog lamp cover 12 is moved to the front bumper. The cover 10 is fixed without using bolts or nuts. Hereinafter, the mounting structure of the fog lamp cover 12 to the front bumper cover 10 will be described in detail.

  FIGS. 2A and 2B show perspective views of the engaging portion 28 as viewed from the inside and the outside in the vehicle width direction, respectively. As shown in these drawings, the engaging portion 28 includes a rectangular parallelepiped pedestal 34 formed integrally with the base 20 and a support erected vertically from the rear wall 34A of the pedestal 34 to the vehicle rear side. A portion 36 and a substantially rectangular flat plate-like claw portion 38 formed so as to protrude from the front end portion of the support portion 36 in the vehicle vertical direction. The interior of the pedestal 34 is hollow, and when viewed in a plan view, only the inner side in the vehicle width direction is connected to the base 20 of the fog lamp cover 12 (see FIGS. 7B and 8B). ). The support portion 36 can be elastically deformed in the vehicle width direction, which is the plate thickness direction. In addition, a pair of upper and lower reinforcing ribs 40 are integrally formed on the back surface (surface in the vehicle width direction) side of the support portion 36 and the claw portion 38. The reinforcing rib 40 is formed in the entire range in the front-rear direction of the support portion 36 and the range in the middle of the claw portion 38 in the front-rear direction. The front end of the reinforcing rib 40 is connected to the pedestal 34. Further, the reinforcing rib 40 is formed in a tapered shape whose width becomes narrower from the front end portion toward the rear end portion in plan view.

  A plurality of functions are added to the claw portion 38. First, proximal end overhangs 38 </ b> A of the claw portions 38 are disposed on both sides of the distal end of the support portion 36, and these proximal end overhangs 38 </ b> A serve as engagement portions with the first support portion 16. Further, both side portions in the width direction (both ends in the vehicle vertical direction) of the claw portion 38 and the surface side of the tip portion (outside in the vehicle width direction) are chamfered, and are thus constituted by a plurality of surfaces (consisting of three surfaces). Slopes (inclined surfaces) 38B and 38C are formed. Further, on the surface side of the claw portion 38, a pressure receiving surface 38 </ b> D that is pressed by a finger during a release operation is formed from the base end portion of the claw portion 38 to an intermediate portion in the extending direction. The direction perpendicular to the surface of the pressure receiving surface 38D is the pressing direction during the release operation.

  FIG. 3 is a perspective view of the lower end portion 16B of the first support portion 16 as viewed from the inside in the vehicle width direction. 4A and 4B show a state in which the engaging portion 28 is engaged with the engaged portion 31 as viewed from the inside and the outside in the vehicle width direction. As shown in these drawings, the lower end portion 16B of the first support portion 16 is erected on the peripheral edge portion of the assembly opening portion 14 of the front bumper cover 10 as described above, and the assembly opening portion. The fitting part 32 including the shelf part 42 extended to the 14th side and the holding wall 44 raised from the inner periphery of the shelf part 42 to the vehicle rear side is provided. The holding wall 44 is formed with a first opening 46 having an opening of a size that can receive the claw 38. The first opening 46 is formed in a rectangular shape when viewed from the vehicle width direction.

  On the other hand, at the center of the shelf 42, there is a second opening 48 formed with an opening surface in a direction intersecting (orthogonal to) the opening surface of the first opening 46 and communicating with the first opening 46. Is formed. The second opening 48 is formed in a rectangular shape when viewed in the vehicle front-rear direction. The opening width of the second opening 48 is set to a width that can receive the support portion 36. Therefore, the opening width of the second opening 48 is narrower than the opening width of the first opening 46. Due to the setting of the opening width, the pair of regulating surfaces 50 are formed on the shelf 42 on both the upper and lower sides of the first opening 46 (side adjacent to the width direction of the second opening 48). By engaging and locking the proximal side overhang 38 </ b> A of the claw portion 38 to these restricting surfaces 50, the engaging portion 28 is fitted and fixed (engaged) with the fitting portion 32 of the first support portion 16. It is like that.

  Further, the slopes 38B and 38C formed on the claw portion 38 interfere with each other at a position adjacent to the portion where the regulation surface 50 of the shelf portion 42 is formed, so that the support portion 36 is moved in the plate thickness direction (vehicle width direction). A slope 42A (inclined surface) is integrally formed as a guide portion that is elastically deformed inwardly. The pair of upper and lower slopes 42A are formed integrally with the shelf 42, and on the opposite side of the regulating surface 50 across the slope 42A, the base of the engaging portion 28 when the claw 38 gets over the slope 42A. A stopper portion 42B is set which abuts the upper wall surface 34A of 34 and stops the movement of the engaging portion 28 in the inserting direction and prevents the engaging portion 28 from being inserted further. When the engaging portion 28 is inserted into the assembly opening 14 and engaged with the first support portion 16, the upper wall surface 34A of the base 34 of the engaging portion 28 comes into contact with the pair of stopper portions 42B. It has become.

  FIG. 5 shows the arrangement of the molds for forming the engaging portion 28 described above. As shown in these drawings, the engaging portion 28 is formed by three types of first mold 52, second mold 54 and third mold 56. A gap 58 having a predetermined thickness is formed between the first mold 52, the second mold 54, and the third mold 56, and the base portion 20 of the fog lamp cover 12 is formed. . Further, another gap 60 that is substantially orthogonal to the gap 58 is formed between the second mold 54 and the third mold 56, and the engaging portion 28 of the fog lamp cover 12 is formed. ing. Note that the first mold 52 has a vehicle reference (in the direction of arrow A in FIG. 5) as the removal direction, and the second mold 54 has a vehicle reference in the direction of the arrow (in the direction of arrow B in FIG. 5). The third mold 56 has a vehicle reference direction and the outer side in the vehicle width direction (the direction of arrow C in FIG. 5) is the removal direction.

(Operation and effect of this embodiment)
Next, the operation and effect of this embodiment will be described.

  6 to 9 are continuous views showing the state until the engaging portion 28 is fitted and fixed to the first support portion 16. In addition, (A) of each figure number is a perspective view, (B) is a plane sectional view when a support part is cut | disconnected in the width direction intermediate part.

  As shown in FIGS. 6A and 6B, the fog lamp cover 12 is first disposed in front of the assembly opening 14 (attachment portion 13) of the front bumper cover 10. Next, the three guide protrusions 30 erected from the fog lamp cover 12 are inserted into the locking holes 29 formed in the mounting portion 13 of the front bumper cover 10, and the engaging portion 28 is connected to the first opening 46 and the second opening 28. Insert into the opening 38 side. That is, the engagement portion 28 is inserted into the first opening 46 and the second opening 38 that communicate with the assembly opening 14 with the direction of the arrow P on the vehicle rear side as the assembly direction. At this time, the assembling operation of the fog lamp cover 12 is guided by the guide protrusions 30 set at three places sliding on the wall surfaces of the first support portion 16 and the second support portion 18. When the engaging portion 28 starts to be inserted into the assembly opening portion 14, the claw portion 38 is not in contact with the first support portion 16.

  When the amount of insertion of the engaging portion 28 into the assembly opening 14 is increased from this state, the slopes 38B and 38C of the engaging portion 28 are the first as shown in FIGS. 7 (A) and 7 (B). It interferes with the slope 42A on the support portion 16 side. For this reason, the engaging portion 28 is pressed inward in the vehicle width direction by the slope 42A, and the support portion 36 is elastically deformed in the plate thickness direction (arrow Q direction in FIG. 7). Then, as shown in FIGS. 8A and 8B, the support portion 36 continues to be elastically deformed until the claw portion 38 gets over the slope 42A. When the rear wall portion 34A of the pedestal 34 of the engaging portion 28 comes into contact with the stopper portion 42B of the first support portion 16, the engaging portion 28 is not further inserted into the first support portion 16 side.

  Then, as shown in FIGS. 9A and 9B, when the support portion 36 gets over the slope 42A, the claw portion 38 moves in the direction opposite to the elastic deformation direction (the arrow in FIG. 9) due to the elastic restoring force of the support portion 36. Displacement in the R direction). As a result, the claw 38 is fitted into the first opening 46 and the support 36 is fitted into the second opening 48. In this state, the base end side protrusion 38A of the claw portion 38 abuts on the restriction surface 50 of the fitting portion 32, and the movement of the claw portion 38 in the disengagement direction (the direction of arrow S in FIG. 4A) is the restriction surface 50. Is regulated (blocked) by

  When the fog lamp cover 12 is removed from the front bumper cover 10, the pressure receiving surface 38D is exposed in the first opening 46, and therefore the pressure receiving surface 38D is located on the inner side in the vehicle width direction with one finger (arrow T in FIG. 4). (Direction side). When the pressure receiving surface 38 </ b> D is pressed inward in the vehicle width direction, the proximal side overhang 38 </ b> A of the claw portion 38 is detached from the regulating surface 50. As a result, the claw portion 38 is detached from the first opening portion 46, and the support portion 36 is separated from the second opening portion 48. As a result, the engaging portion 28 is detached from the engaged portion 31, and the fog lamp cover 12 can be removed from the attaching portion 13 of the front bumper cover 10.

  As described above, according to the present embodiment, when the fog lamp cover 12 is attached, the engaging portion 28 is inserted into the assembly opening portion 14, and the slopes 38B and 38C of the claw portion 38 are disposed on the first support portion 16 side. If it is inserted as it is while interfering with the slope 42 </ b> A, the support portion 36 is automatically bent, and the engagement portion 28 can be engaged with the first support portion 16. Therefore, the fog lamp cover 12 can be easily attached to the front bumper cover 10.

  In addition, after the fog lamp cover 12 is attached, the base end side protrusion 38A included in the claw portion 38 comes into contact with the restriction surface 50 of the fitting portion 32, and the movement of the engagement portion 28 in the direction opposite to the insertion direction is restricted. . Therefore, even if an external force is applied to the fog lamp cover 12 in the direction opposite to the insertion direction (that is, the direction in which the fog lamp cover 12 is removed), the engaging portion 28 is not inadvertently detached from the first support portion 16. This will be described using a proportionality. As shown in FIGS. 10A and 10B and FIGS. 11A and 11B, the thickness direction of the support portion 100 is formed at the distal end portion of the support portion 100. When the engaging portion 104 having a structure in which a claw 104A that protrudes toward the front bumper cover 102 is formed is employed, the portion to be bent (support portion 100) and the portion to be hooked (nail 104A) are the engaging portion 104. The cross-sectional shape of the claw 104A is also a mountain shape. For this reason, the nail | claw 104A remove | deviates from the front bumper cover 102 simultaneously with the support part 100 elastically deforming. Therefore, when the engaging portion 104 according to the proportionality is adopted, it can be said that the claw 104A is easily detached after attachment, while the claw 104A is easily engaged with the front bumper cover 102. On the other hand, in the engaging portion 28 of the present embodiment, the pair of proximal side overhangs 38A included in the claw portion 38 are not on the center line CL of the support portion 36, and the portion to be hooked with the bent portion (support portion 36). The (base end side overhang 38A) is separated, and the base end side overhang 38A and the regulating surface 50 come into contact with each other on a plane orthogonal to the external force in the disengagement direction. For this reason, sufficient fitting force is ensured.

  Further, when the fog lamp cover 12 is removed, it is only necessary to apply a releasing operation force from one direction to the pressure receiving surface 38D provided on the claw portion 38 of the engaging portion 28 from one direction. The engaged state is released. Therefore, the fog lamp cover 12 can be easily removed from the front bumper cover 10.

  In summary, according to the present embodiment having the above-described configuration, the fog lamp cover 12 can be easily attached to the front bumper cover 10 and the fog lamp cover 12 attached to the front bumper cover 10 is not accidentally detached. The operation of removing the fog lamp cover 12 from the front bumper cover 10 is easy.

  In the present embodiment, in a state where the claw portion 38 is fitted to the fitting portion 32, the pressure receiving surface 38 </ b> D provided on the engagement portion 28 can be exposed to the outside from the first opening 46. . For this reason, the release operation force can be directly applied to the pressure receiving surface 38D, and the release operation force can be reduced accordingly. Therefore, when the pressure-receiving surface is not exposed to the outside (for example, the portion where the first opening 46 is formed is a recess having a very thin bottom, and the pressure-receiving surface is not exposed to the outside, When the thin bottom portion is pressed, the release operability can be improved as compared with a structure in which the pressing force is transmitted to the pressure receiving surface through the bottom portion.

  Furthermore, in the present embodiment, when the engaging portion 28 is fitted to the fitting portion 32, the claw portion 38 of the engaging portion 28 is fitted to the first opening 46, and the support portion 36 of the engaging portion 28 is The second opening 48 communicated with the first opening 46 is fitted. At the same time, the proximal side overhang 38 </ b> A of the claw 38 is brought into contact with the regulation surface 50 disposed adjacent to the width direction of the second opening 48. Thus, by forming the second opening 48 in which the opening surface is formed in the direction intersecting the opening surface of the first opening 46 and the opening width is set narrower than the first opening 46, it is inevitably formed. Thus, the adjacent portion of the second opening 48 formed in the width direction can be used as the restriction surface 50. Therefore, according to the present embodiment, the engagement portion 28 can be fitted to the first support portion 16 and the engagement portion 28 can be prevented from coming off from the first support portion 16 in a small space. It can be used effectively.

  In the present embodiment, the first support portion 16 is formed with a stopper portion 42B on the opposite side of the regulating surface 50 across the slope 42A. When the claw portion 38 gets over the slope 42A, the engagement portion 28 is assembled. The insertion operation to the opening 14 for use is stopped. For this reason, as compared with the case where the stopper portion is set on the tip end side of the claw portion 38, the reaction force due to the contact with the stopper portion 42B does not act on the claw portion 38. Therefore, according to the present embodiment, it is possible to improve the durability of the claw portion 38 and the engaging portion 28.

  In addition, according to the attachment structure to the member of the component which concerns on this aspect mentioned above, if the engaged part 70 and the to-be-engaged part 72 of the 1st to-be-engaged part 74 are set to one place, it will be orthogonal to two directions The movement of the engaging portion 70 can be restricted. For example, as shown in FIG. 12A, when the engaging portion 70 is engaged with the engaged portion 72 of the first engaged portion 74, the engaging portion 70 in the vehicle longitudinal direction and the vehicle width direction. Is regulated. For this reason, rattling in these two directions of the engaging portion 70 is suppressed or prevented. Therefore, as shown in FIG. 12 (B), the engaging portion 70 ′ and the engaging portion 70 ′ in which the engaging direction is set to be 90 degrees different from the engaged portion 72 of the first engaged portion 74 and If the engaged portion 72 ′ is set, the movement of the engaging portion 70 ′ is also restricted in the vehicle vertical direction. Therefore, by setting the engaging portions 70, 70 'and the engaged portions 72, 72' of the first engaged portions 74, 74 'to be orthogonal to each other at two or more locations, the vehicle longitudinal direction, the vehicle width The play in the three directions of the direction and the vehicle up-down direction can be suppressed or prevented.

  Moreover, in this embodiment mentioned above, although slope 42A as a guide part was set to the shelf part 42, not only this but a support part can be elastically deformed in the direction in which the fitting fixed state of a nail | claw part is cancelled | released. Any structure can be used. Therefore, for example, a semicircular protrusion may be set on the shelf 42 in a side view instead of the slope 42A.

  Furthermore, in the present embodiment described above, the present invention is applied to the structure for attaching the fog lamp cover 12 to the front bumper cover 10, but the present invention is not limited to this, and the present invention is applied to a structure for attaching other resin parts to the resin member. May be applied.
