An object of the present invention is to provide a vehicle body structure having a fender protector with increased surface rigidity.

According to the present invention, the upper part of the wheel is covered with the inner fender, the fender panel is provided on the outer side of the inner fender, and the fender protector for protecting the fender panel is attached to the outer side of the fender panel. In the vehicle body structure, the inner fender has at least one extending portion that extends toward the fender protector and abuts against a surface on the vehicle width side of the fender protector. A vehicle body structure is provided.

Preferably, a plurality of the extending portions are provided.

Preferably, a reinforcing rib is formed on the extending portion.

Preferably, an attachment portion for attaching the inner fender to the vehicle body is formed on the reinforcing rib.

Preferably, the inner fender is further formed with a bent portion that is bent along the inner surface of the fender protector.

In the present invention, in the vehicle structure having the fender protector for protecting the fender panel, the inner fender that covers the upper side of the wheel extends toward the fender protector and abuts against the inner surface of the fender protector. Has two extensions.

That is, the fender protector is attached to the fender panel and can be supported in the vehicle width direction by the inner fender.

When a load is applied to the fender protector from the outside of the vehicle width, the fender protector is supported from the inside of the vehicle width by the extension part of the inner fender. Therefore, deformation of the fender protector can be suppressed. That is, the surface rigidity of the fender protector is increased.

In addition, in the present invention, a plurality of extending portions that are in contact with the inner surface of the fender protector are provided. That is, the fender protector can be supported by a plurality of extending portions. Since the load from a fender protector can be received reliably, the surface rigidity of a fender protector increases more.

In addition, in the present invention, reinforcing ribs are formed in the extending portion. Therefore, the load applied to the fender protector from the outside of the vehicle width is transmitted to the reinforcing rib together with the extending portion. As a result, the surface rigidity of the fender protector is further increased.

In addition, in the present invention, the reinforcing rib is formed with an attachment portion for attaching the inner fender to the vehicle body. Therefore, the load from the fender protector received by the extension part is transmitted to the vehicle body via the attachment part. That is, since the fender protector is supported by the vehicle body together with the inner fender, the surface rigidity of the fender protector is further increased.

In addition, in the present invention, the inner fender is further formed with a bent portion that is bent along the inner surface of the fender protector. That is, the inner fender is formed with a portion capable of supporting the fender protector in addition to the extending portion. When a load is applied, the bent portion can support the fender protector as well as the extending portion. Therefore, the surface rigidity of the fender protector is further increased.

Therefore, it can suppress that the outer peripheral part 41 goes to a vehicle width outer side. The sealing material 45 provided at the end of the outer peripheral portion 41 is difficult to be separated from the fender panel 30. As a result, the adhesion of the sealing material 45 is easily maintained.

Return to Fig. 3. In addition, three extending portions 51 to 53 that contact the inner surface of the fender protector 40 are provided. That is, the fender protector 40 can be supported by the three extending portions 51 to 53. Since the load from the fender protector 40 can be reliably received, the surface rigidity of the fender protector 40 is further increased.

In addition, the first extending part 51 to the third extending part 53 (reinforcing ribs 71 to 73) are formed in the first extending part 51 to the third extending part 53, respectively. Therefore, the load applied to the fender protector 40 from the outside of the vehicle width is transmitted to the first projecting portion 71 to the third projecting portion 73 together with the first extending portion 51 to the third extending portion 53. Therefore, the surface rigidity of the fender protector 40 is further increased.

In addition, a first attachment portion 81 and a second attachment portion 85 for attaching the inner fender 20 to the frame 11 (vehicle body) are formed on the first protrusion 71 and the third protrusion 73, respectively. The load from the fender protector 40 received by the first extending portion 51 to the third extending portion 53 is transmitted to the frame 11 via the first attaching portion 81 and the second attaching portion 85. That is, since the fender protector 40 is supported by the frame 11 together with the inner fender 20, the surface rigidity of the fender protector 40 is further increased.

Refer to FIG. In addition, the inner fender 20 is further formed with a first bent portion 61 that is bent along the inner surface of the fender protector 40. That is, the inner fender 20 is formed with a portion capable of supporting the fender protector 40 in addition to the first extending portion 51 to the third extending portion 53 (see FIG. 3). When the load is applied, the first bent portion 61 can support the fender protector 40 together with the extending portions 51 to 53.

The second bent portion 62 to the fourth bent portion 64 have the same effect. Description is omitted.

In the present embodiment, the bottom portion 66 of the first bent portion 61 extending in the vehicle width direction is in contact with the edge portion 43 formed at the tip of the inner peripheral portion 42 of the fender protector 40. That is, the bottom 66 and the edge 43 overlap in the vertical direction.

Therefore, the inner fender 20 can suppress the fender protector 40 from moving upward. The adhesion between the fender protector 40 and the inner fender 20 is increased, and the surface rigidity of the fender protector 40 is further increased.

In this embodiment, three extending portions 51 to 53 are formed and four bent portions 61 to 64 are formed. However, the number of extending portions and bent portions formed in the inner fender 20 is appropriately set. It can be increased or decreased. Furthermore, although the first attachment portion 81 and the second attachment portion 85 of the inner fender 20 are fixed to the frame 11 using the clip 15, depending on the material of the inner fender 20, they may be joined by welding or the like. The bottom 66 forming the bent portions 61 to 64 of the inner fender 20 is in contact with the edge 43 of the fender protector 40, but may be separated. That is, the embodiments of the present invention are not limited to these types.
