  In the conventional structure of connecting the horizontal panel portion and the vertical panel portion, the outer side frame (ceiling outer edge member) is fixed to the outer edge in the vehicle width direction of the horizontal panel portion (ceiling surface body), and the vertical panel portion (side surface) The corner member (side edge member) is fixed to the upper edge of the body), and the lower part of the outer side frame and the lower part of the corner member are fitted with the upper part of the outer side frame and the upper part of the corner member being unevenly fitted to each other. And fasten with bolts.

  However, with concavo-convex fitting, it is difficult to always reproduce a stable fitting state (fitting state in which rattling does not occur) for reasons such as dimensional errors of members, and there is a gap in the fitting portion after bolt fastening. It is likely to occur. For this reason, a strong waterproofing process for preventing water from entering the cargo compartment from the fitting portion is required.

  In view of the above situation, the present invention reliably stabilizes the fitting state between the ceiling outer edge member and the side surface upper edge member and secures the clearance in the fitting portion after the ceiling outer edge member and the side surface upper edge member are fastened and fixed. It is an object of the present invention to provide a bonding structure that can suppress the occurrence.

  To achieve the above object, according to a first aspect of the present invention, there is provided a coupling structure for a vehicle cargo compartment upper side portion that couples a lateral surface body defining a side of a cargo compartment and a ceiling surface body defining an upper portion of the cargo compartment. A metal side surface upper edge member that is fixed to the upper edge portion of the side surface body and extends in the front-rear direction, and a metal ceiling outer edge member that is fixed to the outer edge portion in the vehicle width direction of the ceiling surface body and extends in the front-rear direction. A member.

  An upper edge engaging portion, an upper edge fitting portion, and an upper edge fastening portion are integrally formed on the side upper edge member, and an outer edge engaging portion, an outer edge fitting portion, and an outer edge fastening portion are formed on the ceiling outer edge member. It is integrally formed. The upper edge engaging portion and the outer edge engaging portion can be engaged and disengaged at the non-fitting position where the side surface body and the ceiling surface body intersect at an obtuse angle, and while maintaining the engagement state at the non-fitting position, Between the fitting position at which the side face body and the ceiling face body intersect at a substantially right angle and the non-fitting position, the side face body and the ceiling face body with the upper edge engaging portion and the outer edge engaging portion substantially at the center. Allow relative rotation.

  One of the upper edge fitting portion and the outer edge fitting portion has a plate shape having a fitting protrusion, and the other of the upper edge fitting portion and the outer edge fitting portion is a protrusion contact surface on the distal end side and a proximal end side. It is plate shape which has a fitting recessed part. In accordance with the relative rotation of the side surface body and the ceiling surface body from the non-mating position to the mating position, the mating projection comes into contact with the projection abutting surface, and the mating projection slides on the projection abutting surface. Then, at least one of the upper edge fitting portion and the outer edge fitting portion bends and deforms, and the fitting protrusion engages with the fitting recess at the fitting position so that the upper edge fitting portion and the outer edge fitting portion are fitted. .

  In the fitting state in which the upper edge fitting portion and the outer edge fitting portion are fitted, the upper edge fastening portion and the outer edge fastening portion overlap and are fastened and fixed.

  In the above configuration, when connecting the side surface body and the ceiling surface body, the operator engages the upper edge engaging portion and the outer edge engaging portion at the non-fitting position, and fits the side surface body and the ceiling surface body. After the upper edge fitting part and the outer edge fitting part are fitted to each other by rotating relative to each other, the upper edge fastening part and the outer edge fastening part are fastened and fixed. At this time, at least one of the upper edge fitting portion and the outer edge fitting portion is slightly bent and deformed to fit, so even if there is a dimensional error or assembly error of the member, the fitting state Is reliably stabilized, and it is difficult for rattling to occur in the fitting portion after the upper edge fastening portion and the outer edge fastening portion are fastened and fixed, and generation of a gap in the fitting portion can be suppressed. For this reason, it is possible to simplify or omit the waterproofing process for preventing water from entering the cargo compartment from the fitting portion.

The other part has an accommodation recess. With the relative rotation of the side surface body and the ceiling surface body from the non-fitting position to the fitting position, the pressing protrusion enters the housing recess. An elastic rod-like seal member is accommodated in the accommodating recess, and the seal member is pressed by a pressing projection entering the accommodating recess to be elastically deformed to seal the accommodating recess. The elastic force of the deformed seal member suppresses relative movement between the fitted upper edge fitting portion and the outer edge fitting portion.

  In the above configuration, in the fitted state, the seal member is elastically deformed to seal the housing recess, so that water can be prevented from entering the cargo compartment from the engagement portion between the upper edge engagement portion and the outer edge engagement portion. . Moreover, since the elastic force of the deformed seal member suppresses relative movement between the fitted upper edge fitting portion and the outer edge fitting portion, the fitting state is further stabilized.

  A third aspect of the present invention is the coupling structure according to the first or second aspect, wherein the outer edge fastening portion extends inward in the vehicle width direction along the lower surface of the ceiling surface body, and the upper edge fastening portion is fitted. In the state, it overlaps the lower side of the outer edge fastening portion and extends inward in the vehicle width direction. The outer edge fastening portion has a tip portion that extends inward in the vehicle width direction from the upper edge fastening portion in the fitted state.

  In the fitted state in which the upper edge fitting portion 86 and the outer edge fitting portion 56 are fitted, the upper edge fastening portion 83 overlaps the lower side of the outer edge fastening portion 61 and extends inward in the vehicle width direction, and the upper edge fastening portion. 83 and the outer edge fastening portion 61 are fastened and fixed. Further, the elastic force of the deformed gasket 93 suppresses relative movement between the fitted upper edge fitting portion 86 and the outer edge fitting portion 56.

  Next, a process of connecting the ceiling surface body 17 (roof rail outer 31) and the side surface body 18 (rail upper side 40) will be described.

  First, as shown in FIG. 9A, the outer edge of the interior panel 36 in the vehicle width direction is overlapped with the front end 62 of the outer edge fastening portion 61 of the roof rail outer 31, and the lower surface of the ceiling surface body 17 (of the cross roof frame 34). The interior panel 36 is fastened and fixed to the lower surface.

  Next, the side surface body 18 is placed on the work table so that the inner side in the vehicle width direction faces upward, and the side surface body 18 and the ceiling surface body 17 are at an obtuse angle from the non-fitting position as shown in FIG. 9B. The rotation shaft projection 57 of the roof rail outer 31 is placed from above on the support groove 88 of the rail upper side 40 at the crossing position, and the rotation shaft projection 57 on the support groove 88 is substantially centered from the non-fitting position to the fitting position. The ceiling surface body 17 is rotated (see FIG. 9C). While the ceiling surface body 17 rotates from the non-fitting position to the fitting position, the engagement protrusion 87 of the rail upper side 40 is inserted into the engagement recess 59 of the roof rail outer 31 (see FIG. 10A), and the rail upper side. 40 allows the ceiling surface body 17 to rotate while maintaining the engaged state between the upper edge engaging portion 85 of the roof rail 40 and the outer edge engaging portion 55 of the roof rail outer 31. Therefore, the ceiling surface body 17 can be easily and surely moved to the fitting position. Can be rotated.

  In accordance with the rotation of the ceiling surface body 17 from the non-fitting position to the fitting position, the fitting protrusion 60 of the roof rail outer 31 is formed on the protrusion abutting surface 90 of the rail upper side 40 as shown in FIG. Abut and slide on the projection abutment surface 90. As the fitting protrusion 60 slides on the protrusion contact surface 90, at least one of the upper edge fitting portion 86 of the rail upper side 40 and the outer edge fitting portion 56 of the roof rail outer 31 is bent and deformed, and the fitting position is reached. Thus, the fitting protrusion 60 engages with the fitting recess 91 of the rail upper side 40, and the upper edge fitting portion 86 and the outer edge fitting portion 56 are fitted (see FIG. 10C).

  Finally, the upper edge fastening portion 83 and the outer edge fastening portion 61 that overlap vertically are fastened and fixed by bolts 94 and nuts 95.

  According to the present embodiment, when the side surface body 18 and the ceiling surface body 17 are coupled, the operator engages the upper edge engaging portion 85 and the outer edge engaging portion 55 at the non-fitting position, and the side surface After the upper edge fitting portion 86 and the outer edge fitting portion 56 are fitted together by relatively rotating the body 18 and the ceiling surface body 17 to the fitting position, the upper edge fastening portion 83 and the outer edge fastening portion 61 are fastened. Fix it. At this time, since at least one of the upper edge fitting portion 86 and the outer edge fitting portion 56 is slightly bent and deformed and fitted, even if there is a dimensional error or assembly error of the member, the fitting is possible. After the upper edge fastening portion 83 and the outer edge fastening portion 61 are fastened and fixed, it is difficult for rattling to occur in the fitting portion, and generation of a gap in the fitting portion can be suppressed. . For this reason, it is possible to simplify or omit the waterproofing process for preventing water from entering the luggage compartment 21 from the fitting portion (between the upper edge fitting portion 86 and the outer edge fitting portion 56).

  The operator engages the upper edge engaging portion 85 and the outer edge engaging portion 55 at the non-fitting position, and only engages the upper edge engagement by simply rotating the side face body 18 and the ceiling face body 17 to the fitting position. The part 86 and the outer edge fitting part 56 can be fitted. Further, the upper edge fitting portion 86 and the outer edge fitting portion 56 are configured such that at least one of the upper edge fitting portion 86 and the outer edge fitting portion 56 is accompanied by the sliding of the fitting protrusion 60 on the protrusion contact surface 90. Since the fitting protrusion 60 engages with the fitting recess 91 in a state of being bent and deformed, the operator can obtain a moderate feeling of moderation when the fitting is completed. For this reason, the side edge body 18 and the ceiling face body 17 can be combined by reliably fitting the upper edge fitting portion 86 and the outer edge fitting portion 56 with a simple operation.

  In the fitted state, the gasket 93 is elastically deformed to seal the housing recess 89, so that water can be reliably prevented from entering the cargo chamber 21 from the engaging portion between the upper edge engaging portion 85 and the outer edge engaging portion 55. be able to. Further, the elastic force of the deformed gasket 93 suppresses the relative movement between the fitted upper edge fitting portion 86 and the outer edge fitting portion 56, so that the fitting state is further stabilized.

  When the interior panel 36 such as a plate material is attached to the lower surface of the ceiling surface body 17, the operator overlays the outer edge portion of the interior panel 36 in the vehicle width direction on the front end portion 62 of the outer edge fastening portion 61 from below to interior the ceiling surface body 17. A panel 36 is attached. The front end portion 62 of the outer edge fastening portion 61 is exposed to the outside after the side surface body 18 and the ceiling surface body 17 are joined, so that the interior panel 36 can be attached to the ceiling surface body 17 before and after the joining. . Further, by attaching the interior panel 36 to the ceiling surface body 17 before joining, the attaching operation can be performed more easily than when attaching the interior panel 36 after joining.
