JP 2002-19642 A

  However, in the above conventional structure, the wheel arch side end surface of the over fender and the bracket or the door outer panel are joined by rivets, and the rivet is exposed on the wheel arch side end surface of the over fender. Since the wheel arch side end surface of this over fender is a place that is easily visible to the occupant or the like when the door is opened, it is not preferable in terms of appearance.

  Moreover, in the structure which couple | bonds a door and the wheel arch side end surface of an over fender via a bracket, while a number of parts increases by the amount of a bracket, an assembly process will become complicated.

  On the other hand, in the structure in which the outer panel of the door and the wheel arch side end surface of the over fender are directly coupled, there is no inconvenience due to the bracket being interposed, but the member that directly supports the over fender is only the door outer panel. There is a risk that the mounting rigidity on the door side will be insufficient. In addition, high part accuracy is required for the flange portion of the door outer panel and the wheel arch side end surface of the over fender.

  The present invention has been made in view of the above-described problems, has a good appearance when the door is opened, and directly joins the door and the over fender while ensuring sufficient mounting rigidity on the door side. An object of the present invention is to provide a vehicle structure that can be used.

  In order to solve the above problems, a vehicle body structure according to the present invention includes a door, a body panel, and an over fender. The door has a door outer panel and a door inner panel. The door outer panel and the door inner panel form a closed space when their ends are joined to each other. The body panel includes a body outer panel and a wheel arch outer panel, and is disposed on the vehicle inner side than the door. An over fender is provided in the wheel arch peripheral part of a door.

A plurality of first mounting holes and second mounting holes are formed in the wheel arch periphery. The plurality of first mounting holes are arranged along the curve direction of the wheel arch periphery at the end on the wheel house side, and each penetrates the door outer panel and the door inner panel. The second mounting hole is located farther from the wheel house than the first mounting hole and penetrates the door outer panel. A plate-like attachment portion is formed by overlapping and joining the door outer panel and the door inner panel in the region where the first attachment hole is formed in the end portion of the peripheral edge of the wheel arch. Further, among the end portions of the wheel arch peripheral portion, the region between the plurality of first mounting holes and deviating from the first mounting hole in the curve direction of the wheel arch peripheral portion includes a door outer panel and a door inner panel. Is formed as a closed space. Inside the fender, the positioning member attached is inserted from the vehicle outer side to the second mounting hole is projected is provided with a plurality of the mounting member corresponding to a plurality of first mounting holes. The mounted member and the plate-shaped mounting portion at the peripheral portion of the wheel arch are coupled by the mounting member that is inserted into the first mounting hole from the inside of the vehicle.

  In the above configuration, when the over fender is attached to the door, the positioning member of the over fender is inserted into the second attachment hole in the peripheral portion of the wheel arch, and the over fender is temporarily held on the peripheral portion of the wheel arch. In such a state, the position of the first mounting hole in the peripheral portion of the wheel arch and the position of the mounted member of the over fender substantially match. And an attachment member is inserted in the 1st attachment hole of a wheel arch peripheral part from the vehicle inner side, and a to-be-attached member and the plate-shaped attachment part of a wheel arch peripheral part are couple | bonded.

  Further, the positioning member is covered with an over fender on the vehicle outer side and covered with a door inner panel on the vehicle inner side. On the other hand, as for the mounting member, the vehicle outer side is covered with the over fender, but the vehicle inner side is exposed on the outer surface of the plate-shaped mounting part at the wheel arch peripheral part. However, the plate-like mounting part at the wheel arch peripheral part is covered with the wheel arch side end of the over fender that is extended to the inside of the vehicle, compared to the wheel arch side end surface of the conventional over fender. Since it becomes a place that is difficult for passengers to see when the door is opened, the appearance is good.

  Further, since the door and the over fender are directly coupled without interposing other members, the cost is reduced by reducing the number of parts and the mounting workability is improved as compared with the case where other members are intervened. be able to. Moreover, since the wheel arch side end surface of the over fender can be set regardless of the accuracy of the flange portion of the door outer panel, high component accuracy is unnecessary.

  Furthermore, since the over fender is coupled to the plate-like mounting portion in which the door outer panel and the door inner panel are overlapped and joined, the mounting rigidity required on the door side can be sufficiently secured.

In addition, among the end portions of the wheel arch peripheral portion, between the plurality of first mounting holes and in a region deviating from the first mounting hole in the curve direction of the wheel arch peripheral portion, a door outer panel and a door inner panel are provided. The wheel arch required for the door itself is secured by the closed space and the plate-like mounting portion, while ensuring sufficient mounting rigidity of the over fender required on the door side. The rigidity of the end of the peripheral edge can be sufficiently ensured.

  ADVANTAGE OF THE INVENTION According to this invention, the appearance on the appearance at the time of opening of a door becomes favorable, and a door and an over fender can be joined directly, ensuring sufficient installation rigidity of the door side.
