The upper reinforcement 51 and the lower reinforcement 52 are joined to each other at a corner portion 21a of the frame portion 21 in front of the vehicle. The corner 21a is a connecting portion of the upper frame 24 that extends obliquely upward from the front end of the lower frame 25 toward the rear of the vehicle. In this connection part, as shown in FIG. 2, the edge part which forms the opening 23 of the outer panel 40 is comprised so that it may curve in circular arc shape.

  As shown in FIG. 3, the inner panel 30, the outer panel 40, and the reinforcement 50 are respectively joined to the edge part forming the opening 23 of the frame part 21 and the edge part forming the outer shape of the panel with the joining flange 33, 43 and 53 are formed. These joining flanges 33, 43, 53 are joined to each other so that the upper frame part 24, the lower frame part 25, and the rear frame part 26 form a closed section in principle. Specifically, the joining flange 43 is configured to be joined to at least one of the joining flange 53 and the joining flange 33 in principle.

  The outer panel 40 is formed with a joint surface 47 for attaching the sub window glass 11. The joint surface 47 is a substantially triangular annular plane in which the peripheral portion of the opening 23 is displaced by the stepped portion 48 to the inner side in the vehicle width direction than the outer design surface 46 of the outer panel 40. Since the joint surface 47 is displaced inward in the vehicle width direction, when the sub window glass 11 is attached, the vehicle outer surface of the sub window glass 11 and the outer design surface 46 are substantially flush with each other. Yes. The edge portion of the joint surface 47 that forms the opening 23 corresponds to the joint flange 43.

  FIG. 4 is a horizontal sectional view of the corner portion 21 a of the frame portion 21. As described above, in the inner panel 30, the outer panel 40, and the reinforcement 50, in principle, the joining flanges 33, 43, and 53 are joined to each other at the edge portion of the frame portion 21, but the corner portion 21a is This principle is different. That is, in the corner portion 21a, the joint flanges 33 and 53 of the inner panel 30 and the reinforcement 50 are joined to each other, but the edge portion (joint flange 43) that forms the frame portion 21 of the outer panel 40 is the reinforcement. Are not joined to the inner panel 30 via the reinforcement 50 or the reinforcement 50.

  Specifically, the inner panel 30 does not extend outward in the vehicle width direction to the position of the joint surface 47 of the outer panel 40, and the joint flange 33 is spaced from the joint surface 47 in the vehicle width direction by a predetermined distance d1 in the vehicle width direction. Is located.

  Further, the reinforcement 50 does not extend outward in the vehicle width direction to the position of the joint surface 47 of the outer panel 40, and the reinforcement 50 has an inner side in the vehicle width direction before a predetermined distance to the position of the joint surface 47. In addition, a bent portion 54 is formed extending obliquely toward the center of the frame portion 21. The joint flange 53 is formed so as to extend from the inner end in the vehicle width direction of the bent portion 54 toward the center of the frame portion 21 along a plane formed by the joint surface 47. Thus, the joining flange 53 is displaced inward in the vehicle width direction by the bent portion 54.

  On the other hand, the joint flange 43 of the outer panel 40 is outside the opening 23 of the frame portion 21 (in the front of the vehicle in FIG. 4) rather than the ends of the joint flanges 33 and 53 of the inner panel 30 and the reinforcement 50 in a side view. Is located. Specifically, in the outer panel 40, the edge portion that forms the opening 23 of the joining flange 43 is positioned in a direction away from the center portion of the opening 23 by a distance d2 than the edge portion that forms the opening 23 of the joining flanges 33 and 53. It is formed as follows. The bent portion 54 starts to bend from the outside of the opening 23 rather than the inner edge portion of the joint surface 47, and the vehicle width between the bent portion 54 and the joint surface 47 as it goes to the inner edge portion of the joint surface 47. The direction distance is large.

  FIG. 5 is a horizontal sectional view in the vicinity of the upper end of the corner 21a. As the inner panel 30 and the reinforcement 50 move away from the corner portion 21a, the distance separating the joining flange 43 of the outer panel 40 and the joining flanges 33 and 53 in the vehicle width direction is the distance d1 at the central portion of the corner portion 21a. It is comprised so that it may become gradually smaller than. That is, in the present embodiment, when the distance from the corner portion 21a is increased, the step in the vehicle width direction formed in the reinforcement 50 by the bent portion 54 disappears, and the joining flanges 33 and 53 are connected to the joining flange 43 of the outer panel 40. Approach the width direction.

As shown in FIG. 5, the joining flange 43 of the outer panel 40 is also displaced in the direction away from the center of the frame portion 21 rather than the joining flanges 33 and 53 at the upper end portion of the corner portion 21 a.
Then, as shown in FIG. 6, the joint flange 43 of the outer panel 40, the joint flange 33 of the inner panel 30, and the joint flange 53 of the reinforcement 50 are joined together at a portion that is disengaged upward from the corner 21 a. The inner edge of the part 21 is formed.

  In the present embodiment, as described above, the outer panel 40 is separated from the reinforcement 50 by the distance d1 in the vehicle width direction at the corner portion 21a. Therefore, the sound insulation performance and rigidity are reduced by this gap. Therefore, in this embodiment, the shielding member 70 shown in FIG. 7 is arranged so as to fill this gap.

The shielding member 70 is disposed on a resin-made or metal-made main body 71 extending along the upper frame portion 24 so as to fill the gap, and a front surface of the vehicle body 71 (a surface on the back side of the gap). It consists of the foam 75 (refer FIG. 4, FIG. 5). The foam 75 is formed by foaming a foam material 75 a applied to the main body 71. FIG. 7 shows a state before the foamed material 75a is foamed.
A thin plate-like engaging portion 72 is formed on the upper end side of the main body portion 71 so as to extend into the back of the gap, and a protrusion 73 is formed so as to protrude from the engaging portion 72 inward in the vehicle width direction. Has been. The main body 71 is formed with a branch engagement portion 74 that branches inward in the vehicle width direction from the middle on the lower end side.

The upper reinforcement 51 is provided with a processing reference hole 51a, and the projection 73 of the shielding member 70 is fitted into the processing reference hole 51a.
The upper reinforcement 51 and the lower reinforcement 52 are partially overlapped so that the lower reinforcement 52 covers the lower end of the upper reinforcement 51 at the corners 21a, and the overlapping portions are joined together. Has been. In this overlapping portion, a gap in the vehicle width direction is formed at a portion facing the outside of the vehicle, and the branch engagement portion 74 of the shielding member 70 is inserted into the gap from above.

  The shielding member 70 is attached to the reinforcement 50 by the engaging portion 72 and the branch engaging portion 74 after the inner panel 30, the reinforcement 50, and the outer panel 40 are joined together. At this time, the shielding member 70 is in a state where the foam material 75 a is applied to the main body 71. In the painting process, the foamed material 75a is foamed by the heat during the heat treatment after spraying the paint, and the foam 75 is formed. The foam material 75a is foamed by heating to form a foam 75 by increasing the volume in the rear side of the gap and in the vehicle width direction so as to fill the gap from the front surface of the vehicle body 71.

Next, the operation of the side body structure 1 of the present embodiment will be described.
In the side body structure 1 of the present embodiment, the joint flange 53 of the reinforcement 50 is displaced inward in the vehicle width direction by the bent portion 54 in the corner portion 21a of the frame portion 21 forming the sub window 10 in front of the vehicle. The inner flange 30 of the inner panel 30 is joined. On the other hand, the joining flange 43 of the outer panel 40 is positioned on the outer side in the vehicle width direction without being joined to the joining flanges 33 and 53. Further, the inner edge portion of the joint flange 43 is formed so as to be located in a direction away from the center portion of the opening 23 of the frame portion 21, rather than the inner edge portions of the joint flanges 33 and 53.

  Here, as in the prior art, when the joint flange 43 of the outer panel 40 is bent so as to be displaced inward in the vehicle width direction from the joint surface 47 and joined to the joint flange 53 and the joint flange 33 to form a closed cross section, Since it is difficult to bend the joining flange 43 so as to be extremely displaced inward in the vehicle width direction, the joining flange 43 must be displaced via an inclined surface. Thereby, the joining flange 43 will extend to the position nearer the center part of the opening 23 of the frame part 21 than in the case of this embodiment. Therefore, in the corner portion 21a, the parting line that allows the outside of the vehicle to be visually recognized from the inside of the vehicle through the opening 23 of the frame portion 21 is retracted to the rear of the vehicle, and the visible range is narrowed.

  On the other hand, in the present embodiment, the joining flange 43 of the outer panel 40 is not joined to the joining flanges 33 and 53 at the corner portion 21a and is offset by the distance d1 outside in the vehicle width direction. The joint portion of the flanges 33 and 53 can be positioned in front of the vehicle as compared with the conventional case, thereby suppressing the parting line from retreating and ensuring a wide outside visible range.

  Furthermore, in this embodiment, the inner edge part of the joining flange 43 is located in a direction (vehicle front) away from the center part of the opening 23 of the frame part 21 by a distance d2 from the inner edge parts of the joining flanges 33 and 53. Thus, the parting line that is blocked by the inner edge of the joint flange 43 is enlarged to the outside of the frame portion 21, and a wider visible range outside the vehicle can be secured.

  In the present embodiment, the joint flange 43 of the outer panel 40 is not joined to the joint flange 53 of the reinforcement 50 in the corner portion 21a, but at least the joint flange 53 and the joint flange 33 in the other frame portion 21. Joined with one. As a result, a closed cross-section structure can be formed at the portion where the joint flange 43 is joined to the joint flanges 53 and 33, and rigidity and sound insulation performance can be ensured.

  In the present embodiment, since the shielding member 70 is disposed so as to fill the gap between the outer panel 40 and the reinforcement 50 also at the corner portion 21a, a closed cross-sectional structure is formed via the shielding member 70. , Rigidity and sound insulation performance can be ensured. Further, the shielding member 70 includes a foam 75. Since the foam 75 is disposed so as to fill a gap between the outer panel 40 and the reinforcement 50, the shielding member 70 is interposed between the outer panel 40 and the reinforcement 50. It is possible to improve the sound insulation performance for shielding the transmitted sound.

  In the present embodiment, the shielding member 70 has the engaging portion 72 fitted in the processing reference hole 51 a of the upper reinforcement 51, and the branch engaging portion 74 is overlapped between the upper reinforcement 51 and the lower reinforcement 52. The shielding member 70 can be reliably attached to the reinforcement 50 with a simple configuration because it is inserted into the gap formed in the portion. Even if the engaging portion is locked in the machining reference hole formed in the lower reinforcement 52 and the other engaging portion is locked in the upper reinforcement 51, the shielding member can be attached to the reinforcement. Good.

  In the above-described embodiment, the side body structure 1 is configured so that only the corner portion 21a on the vehicle front side of the frame portion 21 expands the parting line to the outside of the frame portion 21, but the present invention is not limited thereto. Also, the parting line may be enlarged to the outside of the frame part 21 also in parts other than the corner part 21a. For example, such a region may be provided at an intermediate position in the length direction of the upper frame portion 24.
