  The flange portion 22 is formed so as to extend from the base end edge 2A of the fender panel 2 once inward in the Y direction and then toward the front side, and is arranged and hidden inside the front bumper. It has become. The flange portion 22 is formed in a substantially rectangular plate shape whose longitudinal direction is the inclination direction of the base end edge 2A.

  The flange portion 22 includes a first plate portion 22A on the front side in the X direction, a second plate portion 22B on the rear side in the X direction, and a step portion 22C formed between the first plate portion 22A and the second plate portion 22B. And having. Since the first plate portion 22A is arranged on the inner side in the Y direction than the second plate portion 22B, the first plate portion 22A and the second plate portion 22B are arranged shifted in the Y direction. The step portion 22C is inclined so as to go outward in the Y direction as it goes backward in the X direction.

  The first plate portion 22A is provided with a lamp fixing portion 221 to which the headlamp 4 is fixed and a bracket connection portion 222 to which a bracket 5 described later is connected. The lamp fixing part 221 and the bracket connection part 222 are formed in a through hole shape. By arranging the bracket connecting portion 222 on the lower side of the lamp fixing portion 221 in the Z direction, the lamp fixing portion 221 and the bracket connecting portion 222 are arranged in the Z direction. “Aligned in the Z direction” is not limited to an arrangement in which when one through hole is translated in the Z direction, the center thereof overlaps the center of the other through hole. An arrangement is also included in which at least a portion thereof overlaps the other through-hole when moved in the Z direction.

  As shown in FIG. 4, two ribs 223 extending along the Z direction are formed on the first plate portion 22A. The two ribs 223 are arranged so as to sandwich the lamp fixing portion 221 and the bracket connecting portion 222 from the X direction. The rib 223 may be formed on the outer surface in the Y direction of the first plate portion 22A or may be formed on the inner surface.

  The second plate portion 22B is provided with a through hole-like rear connection portion 224 to which the bracket 5 is connected. The rear connection portion 224 is disposed on the rear side of the bracket connection portion 222 and is disposed at the same height as the bracket connection portion 222 in the Z direction. That is, when the rear connecting portion 224 is translated in front in the X direction and translated inward in the Y direction by the step height of the stepped portion 22C, a part of the rear connecting portion 224 overlaps the bracket connecting portion 222. .

  The fender apron 3 is made of, for example, a sheet metal, and supports the suspension of the wheel on the front side. The fender apron 3 is arranged on the inner side in the Y direction of the wheel to constitute the inner side of the wheel house, and as a whole along the YZ plane. It is formed in a plate shape that extends. A plate-like fender extension 31 along the ZX plane extends from the front end of the fender apron 3 toward the fender panel 2 on the outer side in the Y direction.

  A bracket 5 is provided at the tip of the fender extension 31 so as to extend the fender extension 31 further. As shown in FIGS. 5 and 6, the bracket 5 is entirely formed in a T shape by two L-shaped members 51, 52, for example, after joining the two L-shaped members 51, 52 by welding. The fender extension 31 is fixed.

  The 1st L-shaped member 51 which comprises the bracket 5 is comprised by bending a sheet metal, for example, extends from the fender extension part 31 to a Y direction outer side, and is a plate-shaped 1st outer extension part along a YZ plane. 511 and a front arm portion 512 extending from the tip of the first outer extension 511 toward the front side in the X direction and extending along the ZX plane. The second L-shaped member 52 is formed by, for example, bending a sheet metal, extends from the fender extension 31 toward the outside in the Y direction, and has a plate-like second outer extension 521 along the YZ plane, A rear arm portion 522 that extends from the tip of the outer extension portion 521 toward the rear side in the X direction and extends along the ZX plane.

  A plate-like bracket main body 53 extending outward in the Y direction with the fender apron 3 as the base end side is configured by the outer extensions 511 and 521 of the two L-shaped members 51 and 52. Note that the tips of the outer extension portions 511 and 521 are slightly shifted in the Y direction, but the “tip portion” of the bracket body 53 indicates a portion including the tips of the outer extension portions 511 and 521. That is, the front arm portion 512 extends from the front end portion of the bracket main body 53 toward the front side in the X direction, and the rear arm portion 522 extends from the front end portion of the bracket main body 53 toward the rear side in the X direction.

  The front arm portion 512 is overlapped with the inner surface (the inner surface in the Y direction) of the first plate portion 22 </ b> A of the flange portion 22, and a through-hole-shaped connection portion 512 </ b> A that overlaps with the bracket connection portion 222 is formed. The front arm portion 512 is connected to the first plate portion 22A by inserting a fixing member such as a bolt or a pin through the bracket connecting portion 222 and the connecting portion 512A.

  The rear arm portion 522 is overlapped on the inner surface (the inner surface in the Y direction) of the second plate portion 22B of the flange portion 22, and a through-hole-shaped connection portion 522A that overlaps the rear connection portion 224 is formed. By inserting a fixing member such as a bolt or a pin through the rear connection portion 224 and the connection portion 522A, the rear arm portion 522 is connected to the second plate portion 22B.

  On the extended surface of the bracket body 53, the step portion 22C of the flange portion 22 is disposed. Specifically, the step portion 22C is inclined and has a predetermined X-direction dimension, but the end portion on the first plate portion 22A side of the step portion 22C and the second L of the bracket main body 53. The X-direction position of the second outer extension 521 of the character-shaped member 52 is substantially the same. Thus, when the bracket main body 53 having a predetermined thickness (dimension in the X direction) is virtually extended, at least a part of the bracket main body 53 is part of the step portion 22C having a predetermined width (dimension in the X direction). It only has to be overlapped.

  The bracket 5 is fixed to the fender extension 31 from the front side in the X direction. That is, the first outer extension 511 of the first L-shaped member 51, the second outer extension 521 of the second L-shaped member 52, and the fender extension 31 are overlapped in this order from the front side in the X direction. It is done. The fender extension 31 may be sandwiched from the X direction by the outer extensions of the two L-shaped members.

  In the fender connection structure 10 as described above, the connection portion 512A of the bracket 5 and the bracket connection portion 222 of the flange portion 22 are connected, and the connection portion 522A and the rear connection portion 224 are connected, whereby the fender panel 2 and the fender. The apron 3 is connected to the apron 3 via the bracket 5. In addition, a flange having a through hole for inserting the fixing member is provided at the lower end of the headlamp 4. The headlamp 4 is fixed to the fender panel 2 by superimposing the flange on the inner side in the Y direction of the flange portion 22 of the fender panel 2 and inserting a fixing member such as a bolt into the through hole of the headlamp 4 and the lamp fixing portion 221. And supported from below. At this time, as shown in FIG. 7, the bumper holder 6 for holding the front bumper is attached to the flange portion 22.

  The bumper holder 6 holds the rear end portion of the front bumper, and is provided so as to improve the design by keeping the base end edge 2A of the fender panel 2 and the rear end edge of the front bumper substantially parallel to each other. It is a resin member. The bumper holder 6 is formed in a plate shape that is overlapped on the outer side in the Y direction of the flange portion 22, and a plurality of locking portions 61 for locking the rear end edge of the front bumper are provided on an end surface facing the base end edge 2 </ b> A. Is provided.

  A mounting hole 62 having a through hole shape is formed at a position of the bumper holder 6 that overlaps the lamp fixing portion 221 of the flange portion 22. By inserting the fixing member through the through hole of the headlamp 4, the lamp fixing portion 221 and the mounting hole 62, the headlamp 4, the fender panel 2 and the bumper holder 6 are fixed together by fastening. As described above, the lamp fixing portion 221 also functions as a holder attachment portion for attaching the bumper holder 6.

  According to such a present Example, there exist the following effects. That is, in the flange portion 22 of the fender panel 2, the lamp fixing portion 221 to which the headlamp 4 is fixed below the boundary portion 21 and the bracket connection portion 222 to which the bracket 5 is connected are arranged in the vertical direction. Thus, the stress applied from the headlamp 4 to the flange portion 22 is easily transmitted to the fender apron 3 through the bracket 5.

  Here, as a comparative example, a configuration in which the lamp fixing portion and the bracket connecting portion are arranged in the front-rear direction will be considered. In such a configuration, although the flange portion is connected to the fender apron 3 via the bracket, the flange portion supports the headlamp 4 from below, so that stress applied from above by the headlamp 4 is applied to the fender. It is difficult to be transmitted to the apron 3. On the other hand, according to this embodiment in which the lamp fixing portion 221 and the bracket connecting portion 222 are arranged in the vertical direction, the stress applied from the headlamp 4 is easily transmitted to the fender apron 3, and the stress to the fender panel 2 is increased. Concentration can be suppressed.

  In addition, a rear connection portion 224 to which the bracket 5 is connected is further provided on the rear side of the bracket connection portion 222 in the flange portion 22 so that stress applied from the headlamp 4 is transmitted to the fender apron 3 at two front and rear positions. can do. As a result, the flange portion 22 is less likely to vibrate in the Z direction at the front end portion where the lamp fixing portion 221 and the bracket connection portion 222 are provided relative to the rear end portion where the rear connection portion 224 is provided. Therefore, the headlamp 4 fixed to the lamp fixing portion 221 and supported from below by the flange portion 22 is less likely to vibrate in the Z direction.

  Furthermore, the bracket 5 has the front arm part 512 and the rear arm part 522, so that one arm part is connected from the front end of the bracket body 53 as compared with the configuration in which one arm part is connected to the bracket connection part 222 and the rear connection part 224. The distance to the parts 512A and 522A can be shortened. Thereby, the rigidity of the arm parts 512 and 522 can be improved and bending can be suppressed.

  Moreover, the rigidity of the fender panel 2 can be improved because the flange portion 22 includes the first plate portion 22A, the second plate portion 22B, and the step portion 22C. Furthermore, the bracket 5 is constituted by two L-shaped members 51 and 52, and the step portion 22C is disposed on the extended surface of the bracket main body 53, so that the arm portion 512 corresponds to the step height of the step portion 22C. By shifting 522 in the Y direction, the arm portions 512 and 522 can be easily overlapped with each of the first plate portion 22A and the second plate portion 22B shifted in the Y direction.

  Furthermore, since the lamp fixing portion 221 functions as a holder attaching portion for attaching the bumper holder 6 for holding the front bumper, the bumper holder 6 can be attached to the flange portion 22. At this time, the flange portion 22 is provided with a lamp fixing portion 221 as a holder attachment portion and a bracket connection portion 222, so that stress applied to the flange portion 22 from the front bumper is applied via the bracket 5. It can be transmitted to the fender apron 3.

  In addition, this invention is not limited to the said Example, The other deformation | transformation etc. which can achieve the objective of this invention are included in this invention.

  For example, in the above embodiment, the lamp fixing portion 221 also functions as a holder mounting portion, but the holder mounting portion may be provided in a portion other than the lamp fixing portion in the flange portion, and the fender panel may be In addition to the flange portion provided with the lamp fixing portion, a flange portion provided with a holder mounting portion may be provided.

  Moreover, in the said Example, although the flange part 22 shall have 22 A of 1st board parts and the 2nd board part 22B arrange | positioned on the Y direction outer side from 22 A of 1st board parts, a bracket connection part The 1st board part provided with may be arrange | positioned on the Y direction outer side rather than the 2nd board part provided with the back connection part. Moreover, it is good also as a structure by which a bracket connection part and a back connection part are formed on substantially the same plane, and a flange part does not have a level | step-difference part.

  Moreover, when the flange part does not have a level | step-difference part, a bracket does not need to be comprised by two L-shaped members. For example, the whole T-shaped bracket may be configured by joining another plate-like member substantially vertically to the central portion of one plate-like member. Further, with respect to one plate-like member extending outward in the Y direction, a part of its tip is bent toward the front side in the X direction to form a front arm portion, and the other part is directed rearward. A bracket that is entirely T-shaped may be formed by forming a rear arm portion by bending. Moreover, an arm part is not limited to what is extended from the front-end | tip part of a bracket main body, You may extend from an intermediate part.

  Moreover, in the said Example, although the bracket 5 shall have the front arm part 512 and the back arm part 522, a bracket has only one arm part extended toward X direction front side or back side. May be. According to such a configuration, for example, a sheet metal bent into an L shape can be used as the bracket, and the bracket can be easily formed.

  In the above-described embodiment, the rear connection portion 224 is further provided on the rear side of the bracket connection portion 222. However, a connection portion other than the bracket connection portion 222 may be provided on the front side of the bracket connection portion 222. It may be provided on the lower side. Further, the bracket and the flange portion may be connected at only one place.
