(Operation and effect of roof joint structure for vehicles)
Next, functions and effects of the vehicle roof joint structure will be described.

  First, the fixing member 28 is attached to the rear surface 12A of the roof panel 12 in accordance with the position of the notch 26C1 of the roof panel 12 shown in FIG. More specifically, the locking piece 26 of the roof panel 12 is inserted between the holding piece 38 and the holding piece 40 of the fixing member 28. As shown in FIG. 2, the second locking portion 26 </ b> C of the locking piece 26 is in contact with the curved portion 40 </ b> A of the sandwiching piece 40, and the second portion between the protrusion 42 and the vertical wall portion 40 </ b> B. The locking part 26C is clamped, and the first locking part 26B is clamped between the clamping part 38B and the receiving part 40C.

  At this time, the adhesive 32 provided on the upper surface 30 </ b> A of the main body 30 of the fixing member 28 is bonded to the back surface 12 </ b> A of the roof panel 12. At this stage, since the adhesive 32 is not cured, even if the adhesive 32 abuts against the back surface 12A of the roof panel 12, the fixing member 28 is positioned in the surface direction of the roof panel 12 via the adhesive 32. It is in a movable state.

  Next, although not shown, the roof panel 12 with the fixing member 28 locked is attached to the side outer panel 20. At this time, the stud bolt 24 provided on the inner flange portion 20 </ b> B of the side outer panel 20 is inserted into the elongated hole portion 34 formed in the fixing member 28.

  Specifically, as shown in FIG. 2, the threaded portion 24 </ b> A of the stud bolt 24 is engaged with a claw portion 34 </ b> A <b> 1 formed on the inner wall surface 34 </ b> A of the elongated hole portion 34. Accordingly, the fixing member 28 is prevented from coming off, and the roof panel 12 is fixed to the side outer panel 20 via the stud bolt 24 and the fixing member 28. As described above, since the long hole portion 34 of the fixing member 28 is engaged with the stud bolt 24, the roof panel 12 can be attached to the side outer panel 20.

  Here, the long hole portion 34 is formed long along the vehicle width direction. On the other hand, the inclined wall 20A1 of the side outer panel 20 is inclined inward in the vehicle width direction as it goes downward in the vehicle vertical direction. That is, the position of the fixing member 28 in the vehicle width direction with respect to the stud bolt 24 varies depending on the position of the inclined wall 20A1 of the side outer panel 20 in the height direction (the vehicle vertical direction). For this reason, by forming the elongated hole portion 34 in the fixing member 28, the displacement amount of the fixing member 28 in the height direction of the side outer panel 20 is absorbed by the elongated hole portion 34.

  With the roof panel 12 fixed to the side outer panel 20, the space Ra provided between the clamping piece 38 and the back surface 12 </ b> A of the roof panel 12 and the clamping piece 40 and the inclined wall 20 </ b> A <b> 1 of the side outer panel 20 are provided. The formed space Rb may be filled with a structural adhesive. Thereby, the roof panel 12 can be reinforced.

  In a state where the roof panel 12 is fixed to the side outer panel 20, the sealer 44 is applied to the boundary portion between the roof panel 12 and the side outer panel 20. This prevents water from entering through the boundary.

  In the present embodiment, locking pieces 26 that are bent downward in the vehicle vertical direction and inward in the vehicle width direction are provided at both ends of the roof panel 12 in the vehicle width direction. On the other hand, the bent portion 26 </ b> A of the locking piece 26 comes into contact with the inclined wall 20 </ b> A <b> 1 of the side outer panel 20.

  A fixing member 28 is fixed to the inside of the bent portion 26A in the vehicle width direction, and a plurality of the fixing members 28 are arranged along the vehicle front-rear direction. The fixing member 28 is fixed to the side outer panel 20 in a state where the bent portion 26A of the roof panel 12 is in contact with the inclined wall 20A1 of the side outer panel 20.

  That is, the roof panel 12 is fixed (joined) to the side outer panel 20 via the fixing member 28 so that the bent portion 26 </ b> A of the roof panel 12 contacts the inclined wall 20 </ b> A <b> 1 of the side outer panel 20. Thereby, the clearance gap between the roof panel 12 and the side outer panel 20 can be made small.

  As a result, although not shown, a roof molding for hiding the gap becomes unnecessary. Thereby, the operation | work which attaches a roof molding between the roof panel 12 and the side outer panel 20 becomes unnecessary, and while workability | operativity improves, cost reduction can be aimed at.

  In addition, the roof panel 12 and the side outer panel 20 can be formed of different materials by fixing the roof panel 12 to the side outer panel 20 via the fixing member 28. As a specific example, in this embodiment, the roof side rail 14 is formed of a steel plate, but the roof panel 12 is made of a lightweight material such as aluminum, an aluminum alloy, or carbon fiber reinforced resin (CFRP). Yes. Thus, by changing the material of the roof panel 12 from a steel plate to aluminum or the like, it is possible to reduce the weight of the vehicle 10 and improve the steering stability.

  Here, when the members formed of different metals are brought into contact with each other, if the contact surfaces of both members are wet with water or the like, a potential difference occurs between the two members, and either one of the metals may rust (so-called electricity). Food). However, in this embodiment, since the sealer 44 is applied to the boundary portion between the roof panel 12 and the side outer panel 20 so that water does not enter through the boundary portion, such a problem hardly occurs.

  Further, in the present embodiment, the fixing member 28 is configured to include sandwiching pieces 38 and 40 as the locking portions 36 and a long hole portion 34 as the engaging portion. The sandwiching pieces 38 and 40 are engaged with the engaging piece 26 of the roof panel 12, and the elongated hole portion 34 is engaged with the stud bolt 24 provided on the side outer panel 20.

  The long hole 34 is engaged with the stud bolt 24 of the side outer panel 20 in a state where the sandwiching pieces 38 and 40 are locked to the locking piece 26 of the roof panel 12. The panel 12 is fixed to the side outer panel 20. That is, since the roof panel 12 can be fixed to the side outer panel 20 without performing work such as welding, the workability is good and the cost can be reduced accordingly.

  Further, in the present embodiment, the long hole portion 34 extends along the vehicle width direction of the roof panel 12. A plurality of claw portions 34A1 are formed along the depth (D) direction on the inner wall surface 34A of the elongated hole portion 34, and the claw portions 34A1 are engaged with the screw portions 24A of the stud bolt 24. .

  For this reason, the stud bolts 24 are inserted into the elongated holes 34 in a state where the clamping pieces 38 and 40 are locked to the locking pieces 26 of the roof panel 12, but depending on the position of the stud bolts 24 relative to the elongated holes 34. The roof panel 12 is positioned with respect to the vehicle width direction of the side outer panel 20 (described later).

  Further, the roof panel 12 is positioned with respect to the vehicle vertical direction of the side outer panel 20 by the position in the depth (D) direction of the claw portion 34A1 engaged with the screw portion 24A of the stud bolt 24.

  Here, the inclined wall 20A1 of the side outer panel 20 is inclined inward in the vehicle width direction as it goes downward in the vehicle vertical direction. For this reason, the position along the vehicle width direction of the fixing member 28 with respect to the stud bolt 24 differs depending on the position where the bent portion 26A of the roof panel 12 abuts against the inclined wall 20A1 (the position in the vehicle vertical direction). .

  Accordingly, as described above, by forming the elongated hole portion 34 along the vehicle width direction in the fixing member 28, the roof panel 12 is engaged with the side outer panel 20 via the fixing member 28. The positional deviation of the roof panel 12 in the vehicle width direction with respect to the side outer panel 20 can be absorbed.

  In this embodiment, the locking piece 26 of the roof panel 12 is clamped by the clamping pieces 38 and 40 in the vehicle vertical direction. For this reason, in a state where the fixing member 28 is locked to the locking piece 26 of the roof panel 12 via the sandwiching pieces 38 and 40, the fixing member 28 moves along the vehicle vertical direction with respect to the roof panel 12. Although restricted, movement along the vehicle front-rear direction is possible in portions other than the reference position.

  For this reason, when attaching the roof panel 12 to the side outer panel 20, the positional deviation of the roof panel 12 in the vehicle front-rear direction of the side outer panel 20 can be absorbed via the fixing member 28. That is, the positional deviation of the roof panel 12 in the vehicle front-rear direction with respect to the side outer panel 20 can be absorbed while the fixing member 28 is locked to the roof panel 12.

(Modification of this embodiment)
(1) In the above embodiment, as shown in FIG. 3, the fixing member 28 is formed with a long slot 34 along the vehicle width direction. The slot 34 has a closed cross section. Has been. However, like the fixing member 50 shown in FIG. 5, the long hole portion 52 may be formed so as to have an open cross section. As shown in FIG. 2, the claw portion 34 </ b> A <b> 1 is formed in the long hole portion 34, and thus this portion is a so-called undercut in the mold for forming the fixing member 20 in the closed cross section. It becomes a part. For this reason, the mold mechanism in the fixing member 20 is complicated. On the other hand, when the long hole portion 52 is formed with an open cross section, the die for forming the fixing member 50 does not become an undercut portion. Therefore, the mold mechanism in the fixing member 50 is simplified, and the mold cost can be reduced. Further, the mass productivity of the fixing member 50 can be improved by a simple mold mechanism.

(2) In the present embodiment, as shown in FIG. 3, the example in which the stud bolt 24 is provided on the side outer panel 20 has been described. However, the fixing member 28 is engaged with the side outer panel 20. It is not limited to this as long as it is possible. For example, as shown in FIG. 6, a bolt 56 may be provided on the fixing member 54 side by insert molding. In this case, an elongated hole portion 60 as an engaged portion to which the bolt 56 is engaged is formed in the inner flange portion 58 </ b> A of the side outer panel 58, and the bolt 56 is engaged with the inner edge portion of the elongated hole portion 60. become.

  Further, the long hole portion 60 is also formed in the inner flange portion 62 </ b> A of the rail inner panel 62. In this case, in consideration of manufacturing variations between the side outer panel 58 and the rail inner panel 62, the long hole portion 60A formed on the side outer panel 58 side is longer than the long hole portion formed on the rail inner panel 62 side. It is set to be larger in the vehicle width direction than 60B. In FIG. 6, the notch 26C1 (see FIG. 3) is not shown.

(3) Although the example in which the bolt 56 is provided on the fixing member 54 side by insert molding has been described here, the bolt portion 66 may be formed on the fixing member 64 as shown in FIG. Of course.

(4) Furthermore, in this embodiment, as shown in FIG. 2, the bent portion 26 </ b> A of the locking piece 26 of the roof panel 12 comes into contact with the inclined wall 20 </ b> A <b> 1 of the side outer panel 20. That is, in the present embodiment, the bent portion 26 </ b> A is in contact with substantially the entire region in the vehicle front-rear direction on the inclined wall 20 </ b> A <b> 1 of the side outer panel 20.

  However, since it is sufficient that the gap between the roof panel 12 and the side outer panel 20 can be reduced, the roof panel 12 does not necessarily have to be in contact with the side outer panel 20 and is close as long as the sealer 44 does not fall. It is okay to leave it in place. In other words, the “proximity” here refers to a gap within a range where the sealer 44 does not fall, and is a narrow gap that does not require the use of a roof molding. Note that the bent portion 26A may intermittently abut along the vehicle longitudinal direction on the inclined wall 20A1.

(5) Further, in the present embodiment, as shown in FIG. 2, the locking portion 36 of the fixing member 28 is constituted by a clamping piece 38 and a clamping piece 40, and the locking piece 26 formed on the roof panel 12. It is to be locked to. However, the present invention is not limited to this, as long as the fixing member 28 can be locked to the locking piece 26. For example, the locking portion may be configured with a single clamping piece. Needless to say, the locking portion may be made of a material other than the clamping piece.

(6) Furthermore, in the present embodiment, the elongated member 34 is provided in the fixing member 28 and is engaged with the stud bolt 24 provided on the side outer panel 20. However, the present invention is not limited to this as long as the fixing member 28 can be engaged with the engaged portion provided in the side outer panel 20. Further, the engaged portion is not limited to the bolt, and a claw-like portion may be formed.

  Although one embodiment of the present invention has been described above, the present invention is not limited to the above, and various modifications other than the above can be implemented without departing from the spirit of the present invention. Of course.
