  SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle body side structure that can improve the formability of a side outer panel and can select a light weight material.

  The vehicle side portion structure according to claim 1 is arranged on the vehicle side portion, and is formed independently of each of the plurality of skeleton members having a closed cross section and each of the skeleton members, and each of the skeleton members is disposed outside in the vehicle width direction. A side outer panel that covers the door, a door opening formed by the plurality of skeleton members, a side door that can be opened and closed at the door opening, and a seal member that closes a gap between the door opening and the side door; The side outer panel is composed of a plurality of panels including an opening panel that surrounds the door opening and receives the elastic force of the seal member when the side door is closed.

  The vehicle side part structure according to claim 1 is applied to a vehicle having a rocker, a front pillar, a center pillar, a rear pillar, and a roof side rail as frame members, for example. In the vehicle side part structure, for example, a rocker, a front pillar, a roof side rail, and a center pillar form a front side door opening that is a door opening corresponding to the front side door. Further, for example, a rocker, a center pillar, a roof side rail, and a rear pillar form a rear side door opening that is a door opening corresponding to the rear side door. And the vehicle width direction outer side part of a some skeleton member is shape | molded independently of each skeleton member, and is covered with the side outer panel comprised from a some panel. Here, “independent molding” means that the skeleton member is formed of a separate member. The side outer panel includes an opening panel surrounding each door opening. The opening panel is formed so as to maintain the elastic force of the seal member existing between each door opening and the corresponding side door in the closed state of the side door.

  According to the vehicle side part structure of the first aspect, the opening panel corresponding to the door opening and having a complicated shape is separated from the other panels constituting the side outer panel. That is, by dividing the side outer panel into a plurality of panels independent of the skeleton member, it is possible to improve the moldability of the side outer panel and to select a light weight material.

  In the vehicle side part structure according to claim 2, the opening panel has a welded portion to each of the skeleton members.

  In the vehicle side part structure according to the second aspect, the opening panel is fixed to the skeleton member by welding instead of parts such as bolts and rivets. According to the vehicle side part structure, the weight of the vehicle can be reduced, and the manufacturing cost can be reduced.

  In the vehicle side part structure according to claim 3, the opening panel has a bead between a contact surface with which the seal member abuts and the welded portion.

  The “bead” is a protruding portion formed by pressing, bending, or the like on the plate material constituting the opening panel. In the vehicle side part structure according to claim 3, since the bead absorbs the thermal deformation of the opening panel due to welding by providing a bead between the abutting surface with which the seal member abuts and the welded portion, Surface accuracy can be ensured.

  In the vehicle side part structure according to claim 4, the opening panel has an outer edge portion provided on a surface on the outer side in the vehicle width direction of each of the skeleton members or a surface on the side door side.

  Here, the “surface on the side door side” means an inner wall surface that is an inner edge portion of the door opening. In the vehicle side part structure of claim 4, the opening panel does not cover the frame member so as to wrap it. That is, since it is not necessary to perform a complicated drawing process for covering the skeleton member so as to wrap the skeleton member at the outer edge portion of the side outer panel, it is possible to improve the moldability and to select a light weight material. Moreover, the weight reduction of a vehicle body can be achieved because a double part with a frame member reduces in an opening panel.

  The vehicle side part structure according to claim 5 includes a roof side rail as the skeleton member, and a rail garnish that covers the roof side rail as the side outer panel.

  In the vehicle side part structure according to the fifth aspect, a rail garnish that covers the roof side rail, which is a skeleton member, is provided as the side outer panel separately from the opening panel. According to the vehicle side part structure, by providing the panel in units of functions and designs for decorating the roof side rail, the outer plate color of the vehicle body can be easily applied separately.

  The vehicle side part structure according to claim 6 includes a rear pillar as the skeleton member, and a quarter panel that covers an outer portion in the vehicle width direction behind the vehicle including the rear pillar as the side outer panel.

  In the vehicle side part structure according to the sixth aspect, a quarter panel is provided as a side outer panel that covers an outer portion in the vehicle width direction behind the vehicle including a rear pillar that is a skeleton member, in addition to the opening panel. According to the vehicle side part structure, the outer plate color of the vehicle body can be easily painted by providing the panel in units of functions and designs for forming the outer wall surface behind the vehicle.

  ADVANTAGE OF THE INVENTION According to this invention, while improving the moldability of a side outer panel, a weight reduction material can be selected.

(Summary of the first embodiment)
As described above, in the vehicle side part structure 10 of the present embodiment, the rocker 62, the front pillar 50, the center pillar 60, the rear pillar 70, and the roof side rail 80, which are frame members, are covered with a plurality of side outer panels. For example, the front side door opening 22 and the rear side door opening 24 constituted by each frame member are surrounded by the opening panel 14 which is a separate member from each frame member. Specifically, the portions closer to the front side door 32 of the rocker 62, the front pillar 50, the roof side rail 80, and the center pillar 60 are covered with the opening panel 14. Further, portions of the rocker 62, the center pillar 60, the roof side rail 80, and the rear pillar 70 near the rear side door 34 are covered with the opening panel 14. The roof side rail 80 is covered with a rail garnish 16 that is a separate member from the roof side rail 80. Further, an outer portion in the vehicle width direction behind the vehicle including the rear pillar 70 is covered with a quarter panel 18 which is a separate member from the rear pillar 70.

The vehicle side part structure 10 of the present embodiment configured as described above has the following features and effects.
First, the present embodiment is characterized in that a side outer panel that covers each skeleton member from the outside in the vehicle width direction is divided into an opening panel 14, a rail garnish 16, and a quarter panel 18. Here, as in the prior art, the side outer panel in which the outer panel of each skeleton member is integrated needs to correspond to the shape of each skeleton member constituting the door opening and the outer wall surface of the vehicle body. In particular, since the periphery of the door opening has a complicated shape, it is difficult to improve the formability in the case of a side outer panel in which the outer panels of the skeleton members are integrated. On the other hand, in this embodiment, the moldability can be improved by separating at least the opening panel 14 from other panels. Moreover, in this embodiment, metal mold | type and resin material softer than iron like aluminum can be used for a side outer panel by a moldability improving. That is, a light weight material can be selected.

  2ndly, in the opening panel 14 of this embodiment, the outer edge part is provided in the surface of the vehicle width direction outer side of each skeleton member, or the surface by the side door, in other words, the opening panel 14 does not have a skeleton member. It is characterized in that it is not covered so as to wrap up. For example, in the front pillar 50, the outer edge portion of the opening panel 14 on the vehicle front side is provided on the outer wall surface 50 </ b> A, and the opening panel 14 is not covered so as to wrap the front pillar 50. Further, in the roof side rail 80, the outer edge of the opening panel 14 on the vehicle upper side is provided on the outer wall surface 80A, and the opening panel 14 is not covered so as to wrap around the roof side rail 80. Further, in the rear pillar 70, the outer edge of the opening panel 14 on the vehicle rear side is provided on the front wall surface 70A, and the opening panel 14 is not covered so as to wrap around the rear pillar 70. As described above, the opening panel 14 of the present embodiment is not formed into a shape that wraps around each skeleton member, in other words, a hat shape that opens inward in the vehicle width direction in a cross-sectional view. That is, the opening panel 14 of the present embodiment does not require a complicated drawing process at the outer edge portion, so that the formability can be improved. Moreover, in this embodiment, a light weight material can be selected as mentioned above by improving a moldability. Furthermore, in this embodiment, the opening panel 14 covers only a part of the skeleton member. That is, since the double part of a panel reduces between the opening panel 14 and each frame member, the vehicle body 12 can be reduced in weight.

  Thirdly, the side outer panel of the present embodiment is characterized in that it is divided in units of functions and designs. For example, the opening panel 14 serves as a contact portion between a weather strip 42 and a weather strip 44 as seal members provided on each side door 30.
