  However, in the configuration of the invention of Patent Document 1, in order to fix the lower fixing portion of the over fender to the lower end portion of the bracket, it is necessary to secure a flange width to which a rivet can be attached, which increases the vehicle width. There's a problem.

  Further, in the configuration of the invention of Patent Document 2, in order to cover the gap between the periphery of the fender and the tire, the over fender may be bent and formed in an arc shape along the periphery of the fender, even if the over fender is extended downward. Since it is difficult, there is a problem that productivity deteriorates.

  In addition, when the over fender is extended downward, if the user pushes or pulls the lower end of the over fender with a finger, the over fender is easily deformed in the vehicle width direction, so that the rigidity of the over fender is secured. This measure was necessary.

  Here, when the over fender is made of resin, it may be possible to secure the rigidity by integrally forming a reinforcing rib on the over fender, but there is a risk that sink marks or dents may be formed on the decorative surface of the over fender. This is not preferable.

  The present invention has been made in view of the above points, and the object of the present invention is to prevent the over fender from extending in the vehicle width while suppressing the amount of protrusion of the over fender in the vehicle width direction even when the over fender is extended downward. It is to make it difficult to deform in the direction.

  The present invention relates to an overfender structure for an automobile comprising a fender provided on a side portion of a vehicle body, an over fender that covers a peripheral portion of the fender, and a bracket disposed between the over fender and the fender. The following solution was taken.

That is, in the first invention, the lower edge of the over fender extends and projects downward from the lower edge of the fender in a side view,
The bracket is attached to the fender by being locked to the side surface and the lower surface of the fender by a locking member,
The lower end portion of the bracket is formed so that the thickness decreases as it goes downward,
The lower edge of the bracket extends in the same manner as the lower edge of the over fender in a side view or protrudes downward from the lower edge of the over fender ,
The over fender is connected to the side surface of the fender by a connecting portion, and extends inward in the vehicle width direction and is provided between the lower edge of the fender and the lower edge of the bracket in a side view. It is characterized by being engaged with the bracket by a portion .

  In the first invention, since the bracket is locked to the side surface and the lower surface of the fender, the rigidity in the vehicle width direction of the bracket is secured, and even if the user pushes or pulls the lower end of the bracket with a finger, The bracket is difficult to deform. Further, since the thickness is reduced as the lower end portion of the bracket is directed downward, the protrusion amount in the vehicle width direction can be reduced.

  Since the lower edge of the bracket is the same as the lower edge of the over fender in side view or extends below the lower edge of the over fender, the user puts his finger under the fender and pulls the over fender. However, since the finger is applied to the bracket instead of the over fender, the over fender will not be deformed.

  Even when the user presses the over fender with his / her finger in the vehicle width direction, the over fender is supported by being brought into contact with the bracket, so that deformation of the over fender can be suppressed. As a result, it is not necessary to adopt a structure in which a flange is provided at the lower edge of the over fender and connected to the bracket using a rivet or the like as in the prior art, and the amount of protrusion of the over fender in the vehicle width direction can be reduced. it can.

The over fender is coupled to the side surface of the fender by a coupling portion, and is engaged with the bracket by an engagement portion provided between the lower edge of the fender and the lower edge of the bracket in a side view. In this way, by engaging the engaging portion on the upper side of the lower edge of the bracket formed so that the thickness becomes thinner toward the lower side, the engaging portion extending inward in the vehicle width direction is engaged. The support rigidity of the over fender can be improved while sufficiently securing the thickness of the bracket for the purpose.

According to a second invention, in the first invention,
The over fender is connected to a side surface of the fender by a connecting portion, and is disposed with a predetermined gap with respect to the bracket.

  In the second invention, since the over fender and the bracket are disposed with a predetermined gap, a dimensional error and thermal deformation at the time of manufacturing the over fender and the bracket can be absorbed by the gap. Further, even when the over fender vibrates during driving of the automobile or due to wind, the over fender and the bracket are not in contact with each other, so that noise can be prevented.

According to a third invention, in the first or second invention,
The bracket has a side surface mounting portion that is attached to the side surface of the fender, and a lower surface mounting portion that extends inward in the vehicle width direction from a position lower than the side surface mounting portion and is attached to the lower surface of the fender,
The lower surface attaching portion is attached to the lower surface of the fender by being locked by the locking member together with a mud guard disposed below the fender.

  In 3rd invention, the support rigidity of a bracket improves because the side surface attaching part of a bracket is each attached to the side surface of a fender, and a lower surface attaching part is respectively attached to the lower surface of a fender. In addition, since the locking member for mounting the lower surface mounting part of the bracket to the fender is also used for mounting the mud guard that prevents intrusion of muddy water etc., a mounting hole and locking member for mounting the mud guard are separately provided. There is no need to provide it, and the number of parts can be reduced.

According to a fourth invention, in any one of the first to third inventions,
The bracket includes a bracket main body extending in the circumferential direction along the over fender, and a plate-shaped lower surface mounting portion that extends inward in the vehicle width direction from the bracket main body and is attached to the lower surface of the fender. It is characterized by that.

In the fourth invention, since the lower surface mounting portion of the bracket is formed in a plate shape, the amount of downward projection when the lower surface mounting portion of the bracket is mounted on the lower surface of the fender is suppressed, and the bracket in the vehicle width direction is suppressed. A tensile load can be received at the lower surface mounting portion .

  According to the present invention, since the bracket is locked to the side surface and the lower surface of the fender, the rigidity in the vehicle width direction of the bracket is ensured, and even if the user pushes or pulls the lower end of the bracket with a finger, The bracket is difficult to deform. Further, since the thickness is reduced as the lower end portion of the bracket is directed downward, the protrusion amount in the vehicle width direction can be reduced.

  Since the lower edge of the bracket is the same as the lower edge of the over fender in side view or extends below the lower edge of the over fender, the user puts his finger under the fender and pulls the over fender. However, since the finger is applied to the bracket instead of the over fender, the over fender will not be deformed.

  Even when the user presses the over fender with his / her finger in the vehicle width direction, the over fender is supported by being brought into contact with the bracket, so that deformation of the over fender can be suppressed.

It is a side view which shows the structure of the motor vehicle which concerns on this embodiment. It is a side view which shows the state which attached the bracket to the front fender panel. It is AA arrow sectional drawing of FIG. It is a BB arrow sectional view of Drawing 2.

As shown in FIGS. 2 to 4, the lower peripheral edge portion of the front fender panel 21 constituting the front fender is formed in a perfect circular arc shape along the outer peripheral surface of the front tire 14 in a side view. Yes. Here, the upper part of the lower edge of the front fender panel 21 is formed in a shape recessed upward in a side view in order to ensure a sufficient vertical stroke of the front tire 14. Thereby, the clearance gap between the upper side of the peripheral part of the front fender panel 21 and the front tire 14 is large.

  Here, when the gap is large, the appearance is deteriorated. Therefore, the bracket 40 is attached to a position closer to the upper part of the peripheral portion of the front fender panel 21 in order to cover the gap in a side view. The front over fender 30 is formed in an arc shape extending along the peripheral edge of the front fender panel 21 and covers the peripheral edge of the front fender panel 21 and the bracket 40 in a side view. As a result, the bracket 40 is disposed between the front over fender 30 and the front fender panel 21.

  Thus, the bracket 40 can be reduced in size and weight by forming a shape in which only the lower edge upper portion of the front fender panel 21 having a wide interference area of the front tire 14 is recessed upward and providing the bracket 40 only in the recessed portion. Can do. Further, the front tire 14 shown in FIG. 3 shows a state in which the vertical stroke position is at the uppermost position, and thus the front tire 14 and the bracket 40 are arranged on the outer side in the vehicle width direction of the front tire 14. Since the front wheel house 20 is formed in a shape close to a perfect circle along the outer peripheral surface of the front tire 14 in a side view, the gap between the front tire 14 and the front tire 14 can be reduced. , Improve the appearance.

  Hereinafter, a specific configuration of the bracket 40 will be described. The bracket 40 includes a bracket main body portion 41, a side surface attachment portion 42, a lower surface attachment portion 43, and a mud guard holding portion 44.

  The bracket body 41 extends in the circumferential direction along the front over fender 30. The lower end portion of the bracket main body portion 41 is formed so that the thickness decreases as it goes downward. Thereby, the protrusion amount of the bracket 40 in the vehicle width direction can be small while avoiding interference with the front tire 14. A plurality of engagement holes 41a are formed in the bracket main body portion 41 at intervals in the circumferential direction to be engaged with engagement portions 35 of the front over fender 30 described later.

  The side surface mounting portion 42 extends upward from the bracket body portion 41, and is formed with an insertion hole 42a through which a locking tool 48 (locking member) such as a fastener is inserted. In the present embodiment, three side surface attachment portions 42 are provided at intervals in the circumferential direction of the bracket main body portion 41. A plurality of locking holes 25 are formed on the side surface of the front fender panel 21 so as to correspond to the plurality of side surface mounting portions 42, and by locking the locking tools 48 to the locking holes 25, the side surface mounting portions 42 is attached to the side surface of the front fender panel 21.

  The lower surface mounting portion 43 is configured by a plate-like body extending inward in the vehicle width direction from a lower position than the side surface mounting portion 42 in the bracket main body portion 41, and an insertion hole 43 a through which the locking tool 48 is inserted is formed. ing. In the present embodiment, four lower surface mounting portions 43 are provided at intervals in the circumferential direction of the bracket main body portion 41.

  The front fender panel 21 is provided with a fender flange 22 that protrudes inward in the vehicle width direction from the lower edge portion thereof, and constitutes the lower surface of the front fender panel 21. Locking holes 25 are formed in the fender flange 22 of the front fender panel 21 so as to correspond to the plurality of lower surface mounting portions 43, and the lower surface mounting portion is obtained by locking the locking tool 48 to the locking holes 25. 43 is attached to the fender flange 22, that is, the lower surface of the front fender panel 21.

  Thus, since the side surface attaching portion 42 of the bracket 40 is attached to the side surface of the front fender panel 21 and the lower surface attaching portion 43 is attached to the lower surface of the front fender panel 21, the rigidity of the bracket 40 in the vehicle width direction is secured. Even if the user pushes or pulls the lower end of the bracket 40 with a finger, the bracket 40 is hardly deformed.

  The mudguard holding portion 44 is configured by a plate-like body that extends inward in the vehicle width direction from the bracket main body portion 41.
