By the way, when manufacturing the roof panel and the rail side outer on the vehicle body (body) side, a manufacturing error occurs. Therefore, when mass-producing vehicles, the panel side flange of the roof panel of each vehicle and the rail side of the rail side outer It is difficult to keep the vertical distance from the flange constant. If the vertical distance between the rail-side flange and the panel-side flange is different, the adhesive spreads differently between the rail-side flange and the panel-side flange, and the position of the outer end of the adhesive in the vehicle width direction is different. Come on. As described in Patent Document 1, the position of the outer end portion of the adhesive in the vehicle width direction is determined with respect to the amount of the sealant applied when the adhesive is sealed from the outside in the vehicle width direction with a sealant (sealing material). It will have a big impact. When the vertical distance between the rail side flange and the panel side flange is wide, the adhesive does not easily spread outward in the vehicle width direction. Therefore, when applying the sealing material to the corner of the outer end of the panel side flange in the vehicle width direction. In addition, there is a possibility that the sealing material may enter the inside in the vehicle width direction (adhesive side), and a large amount of sealing material may be required.

Therefore, an object of the present disclosure is to provide a vehicle panel joint structure capable of setting the coating amount of the sealing material without being affected by the adhesive and suppressing the coating amount of the sealing material. ..

In order to solve the above problems, the present disclosure is a vehicle panel joining structure in which a roof panel and a body below the roof panel are joined by an adhesive, and the roof side joining plate portion, the body side joining plate portion, and a dam are provided. It is provided with a stopper. The roof-side joint plate portion is provided on the outer edge portion on one side in a predetermined direction of the roof panel and extends along a predetermined extension direction in a state of intersecting the vertical direction. The body-side joint plate portion is provided at the upper end portion on one side of the body, extends along the extension direction in a state of intersecting the vertical direction, and is arranged below the roof-side joint plate portion to be arranged on the roof-side joint plate portion. It is joined to the part with an adhesive to support the roof side joint plate part from below. The damming member is elastically deformed by being pressed by the lower surface of the roof side joint plate portion and the upper surface of the body side joint plate portion, and is between the lower surface of the roof side joint plate portion and the upper surface of the body side joint plate portion. It extends along the extension direction. The lower surface of the roof-side joint plate portion is located on the other side in the predetermined direction from the damming member, and has a roof-side adhesive region that is bonded to the body-side joint plate portion by an adhesive. The upper surface of the body-side joint plate portion is located on the other side of the damming member, faces the roof-side adhesive region from below, and is bonded to the roof-side adhesive plate portion by an adhesive. Has an area. The one-sided edge of the roof-side joint plate is sealed with a sealant. The damming member can block the outflow of the adhesive from the other side of the damming member to the one side of the damming member, and is more than the damming member from the one side of the damming member. It is possible to block the inflow of the sealing material to the other side.

In the above configuration, the damming member is elastically deformed by being pressed against the lower surface of the roof side joint plate portion and the upper surface of the body side joint plate portion, and the lower surface of the roof side joint plate portion and the upper surface of the body side joint plate portion. It is arranged between the and, and can block the outflow of the adhesive from the other side of the damming member to one side of the damming member. For this reason, the vertical distance between the upper surface of the body-side joint plate and the lower surface of the roof-side joint plate becomes narrower than the desired distance due to manufacturing errors of the body or roof panel, and the adhesive is joined on the body side. Even if the adhesive spreads in the predetermined direction between the upper surface of the plate portion and the lower surface of the roof side joint plate portion, the outflow of the adhesive to one side of the damming member is blocked by the damming member. In this way, since the outflow of the adhesive to the one side of the damming member is blocked by the damming member, the vertical direction between the upper surface of the body side joint plate portion and the lower surface of the roof side joint plate portion. Even if the interval becomes narrower than the desired interval and the adhesive spreads in the predetermined direction, the adhesive does not affect the amount of the sealant applied. Therefore, the coating amount of the sealing material can be set without being affected by the adhesive.

Further, the damming member can block the inflow of the sealing material to the other side of the damming member. Therefore, even if the vertical distance between the upper surface of the body-side joint plate portion and the lower surface of the roof-side joint plate portion is greatly increased due to a manufacturing error of the body or roof panel, the sealing material to the other side is widened. Since the inflow of the sealant can be reliably suppressed to a certain position (position of the blocking member), the amount of the sealing material applied is suppressed as compared with the case where the sealing material flows into the other side of the position of the blocking member. be able to.

According to the present disclosure, the coating amount of the sealing material can be set without being affected by the adhesive, and the coating amount of the sealing material can be suppressed.

In the present embodiment, the work of applying the adhesive 40 to the roof-side adhesive region 25 of the lower surface 22 of the roof flange portion 19 of the roof panel 3 and the outer edge 28 of the roof flange portion 19 in the vehicle width direction are sealed by the sealing material 50. The work is performed by a computer-controlled machine (not shown).

When manufacturing the roof panel 3 or the body 5, a manufacturing error occurs in the roof panel 3 and the body 5, so that the lower surface 22 of the roof flange portion 19 of the roof panel 3 is set to interpose the adhesive 40. The size of the gap between the drip rail 11 and the upper surface 23 of the rail bottom plate 16 (hereinafter, referred to as “distance between the roof flange 19 and the rail bottom plate 16”) is determined by each vehicle 1 or by one. The vehicle 1 may also differ depending on the position of the roof flange portion 19 in the front-rear direction. For example, the distance between the roof flange portion 19 and the rail bottom plate portion 16 may be a short distance L2 (see FIG. 5) or a long distance L3 (see FIG. 6) with respect to the ideal distance L1 (see FIG. 4). May become. Therefore, the amount of the adhesive 40 applied to the roof-side adhesive region 25 of the lower surface 22 of the roof flange portion 19 is a distance L3 in which the distance between the roof flange portion 19 and the rail bottom plate portion 16 is longer than the ideal distance L1 (FIG. 6), the lower surface 22 of the roof flange portion 19 and the upper surface 23 of the rail bottom plate portion 16 are set to an adhesive amount (coating amount). Similarly, the sealing material 50 for sealing the outer edge 28 of the roof flange portion 19 in the vehicle width direction is also a distance L3 in which the distance between the roof flange portion 19 and the rail bottom plate portion 16 is longer than the ideal distance L1 (FIG. 6), the outer edge 28 of the roof flange portion 19 in the vehicle width direction is set to a sealable amount (coating amount).

In the above configuration, the dam sealer 24 is joined to the lower surface 22 of the roof flange portion 19 in a state where the roof flange portion 19 of the roof panel 3 and the rail bottom plate portion 16 of the drip rail 11 are joined (hereinafter referred to as “joined state”). It is elastically deformed by being pressed between the upper surface 23 of the rail bottom plate 16 and the lower surface 22 of the roof flange 19 and the upper surface 23 of the rail bottom plate 16. Therefore, when the roof panel 3 is placed on the body 5 from above, the adhesive 40 intersects the lower surface 22 of the roof flange portion 19 and the upper surface 23 of the rail bottom plate portion 16 in the vertical direction. Even if it spreads, the outflow of the adhesive 40 to the outside in the vehicle width direction from the dam sealer 24 can be blocked by the dam sealer 24. Since the outflow of the adhesive 40 to the outside in the vehicle width direction from the dam sealer 24 can be blocked by the dam sealer 24, the distance between the roof flange portion 19 and the rail bottom plate portion 16 is shorter than the ideal distance L1 (L2 ( (See FIG. 5), and even when the adhesive 40 spreads in the vehicle width direction, the outflow of the adhesive 40 to the outside in the vehicle width direction from the dam sealer 24 is blocked by the dam sealer 24. In this way, the outflow of the adhesive 40 to the outside in the vehicle width direction from the dam sealer 24 is blocked by the dam sealer 24, so that the distance between the roof flange portion 19 and the rail bottom plate portion 16 is shorter than the ideal distance L1. (See FIG. 5), and even when the adhesive 40 spreads in the vehicle width direction, the adhesive 40 does not affect the coating amount of the sealing material 50. Therefore, the coating amount of the sealing material 50 can be set without being affected by the adhesive 40.

Further, the dam sealer 24 is fixed to the lower surface 22 of the outer end portion 27 in the vehicle width direction of the roof flange portion 19 and extends long in the front-rear direction, and the lower surface 22 of the roof flange portion 19 and the upper surface of the rail bottom plate portion 16 are joined. Since it is elastically deformed with the dam sealer 24, it is possible to block the inflow of the sealing material 50 inward in the vehicle width direction from the dam sealer 24. Therefore, even when the distance between the roof flange portion 19 and the rail bottom plate portion 16 is longer than the ideal distance L1 (see FIG. 6), the sealing material 50 downward of the roof flange portion 19 Since the inflow of the dam sealer 24 can be reliably suppressed to a certain position P (the position of the outer surface 31 of the dam sealer 24 in the vehicle width direction), the sealing material 50 is the roof flange portion 19 inside the vehicle width direction of the position of the dam sealer 24. The coating amount (set amount) of the sealing material 50 can be suppressed as compared with the case where the sealing material 50 flows downward.

Therefore, according to the present embodiment, the coating amount of the sealing material 50 can be set without being affected by the adhesive 40, and the coating amount of the sealing material 50 can be suppressed.

In the present embodiment, the roof flange portion 19 of the roof panel 3 is joined to the rail bottom plate portion (body side joint plate portion) 16 of the drip rail 11, but the present invention is not limited to this, and for example, The roof flange portion 19 may be joined to the outer upper plate portion 12 of the rail portion 7 on the body 5 side. In this case, the outer upper plate portion 12 functions as a body-side joint plate portion.
