Thus, the joint between the roof panel R1 and the roof side panel R2 is concealed. The roof molding 60 has a surface portion 61 that closes the concave groove S and a leg portion 62 formed on the back side thereof, and a lip 63 is formed on the lower portion of the leg portion 62 for maintaining the posture. In general, it is made of an extruded product of resin. Further, with respect to the end portion of the roof molding 60, the end cap 64 is formed by injection molding or the like, or a part of the leg portion 62 is cut and the attachment portion 65 is formed by injection molding or the like on the cut trace. .
[0003]
As an attachment structure of the roof molding 60, as shown in FIGS. 8 and 9, the clip 70 is fixed in the groove S of the roof, and the attachment portion 65 of the roof molding 60 is engaged with the clip 70. It is known (see Patent Document 1). The clip 70 has a substantially concave cross-section in which inward engagement claws 72 and 72 are formed on the upper portions of the opposing side walls 71 and 71, and the side walls 71 and 71 have intermediate positions in the longitudinal direction of the clip 70. Positioning slits 73 and 73 are respectively formed from the upper end. On the other hand, the mounting portion 65 of the roof molding 60 is formed with an engaging projection 66 that engages with the engaging claw 72 of the clip and a positioning pin 67 that fits into the positioning slit 73 on the side surface.
[0004]
The roof molding 60 is attached by aligning the roof molding 60 so that the positioning pins 67 are correctly positioned above the positioning slits 73 of the clip, and in that state, the roof molding 60 is strongly attached to the clip 70. This is done by pushing. As a result, the engagement protrusion 66 of the roof molding 60 gets over the engagement claw 72 of the clip 70 and enters and engages between the engagement claw 72 and the bottom surface 74. The movement is restricted, and the positioning pin 67 is fitted into the positioning slit 73 of the clip 70, so that the movement of the molding 60 in the length direction is restricted.

[Problems to be solved by the invention]
However, in the roof molding mounting structure using the clip 70, it is difficult to say that the strength of the positioning pin 67 of the roof molding is sufficient, and the roof molding 60 cannot withstand expansion and contraction due to the temperature change and may be damaged. . In particular, the roof molding 60 is located on the outer surface of the vehicle body, becomes extremely hot due to direct sunlight in summer, and becomes very cold due to snow accumulation in winter. Further, as shown in FIGS. 7 and 8, in the structure in which the roof molding 60 is attached so that the end 60a of the roof molding 60 is in contact with the window molding W, if the positioning pin 67 is damaged, the positioning Since the movement restriction in the length direction of the roof molding 60 by the pins 67 is released, the window molding W and the roof molding 60 are lifted by the expansion and contraction of the roof molding 60, or between the wind molding W and the roof molding 60. There is a possibility that gaps are created and the aesthetic appearance is impaired.
[0008]
In addition, when the roof molding 60 is attached, the roof molding 60 needs to be strongly pressed into the clip 70. Therefore, if the position of the roof molding 60 is not correct, the positioning pin 67 is attached to the clip 70. The roof molding 60 may not be attached in some cases because it is strongly pressed against the upper end of the side wall 71 and easily breaks.
[0009]
Further, in the structure in which the bracket is attached to the roof molding by caulking, not only an extra man-hour is required for the caulking work, but there is a problem that the bracket is expensive.
[0010]
[Problems to be solved by the invention]

Further, in this embodiment, a widened portion elastic deformation recess 36 is formed on the back surface of the widened portion 35. When the roof molding 20 is slid, the widened portion elastic deformation recess 36 is formed so that when the widened portion 35 is pressed by the side walls 11 of the clip 10 in the direction of narrowing the width, To be elastically deformed (width-reduced elastic deformation) in the direction of narrowing. Then, the sliding of the roof molding 20 is further facilitated by a synergistic effect that the side walls 11 and 11 of the clip 10 are pushed outward by the widened portion 35 and deformed to widen. The widened portion elastic deformation recess 36 may be formed at least on the back surface portion of the widened portion 35. In this example, the widened portion 35 is pressed when the widened portion 35 is pressed by the side walls 11, 11 of the clip 10. In order to further facilitate the elastic deformation, the back surface of the widened portion 35 is continuously formed from the back surface of the engaging portion 39. The width, depth, and the like of the widened portion elastic deformation recess 36 are appropriately determined according to the material of the roof molding 20, the size of the widened portion 35, and the like.

[0027]
Subsequently, the clip 10 is moved from the insertion portion 33 to the widening portion 35 and further to the engagement portion 39 by sliding the roof molding 20 in the direction C opposite to the widening portion 35, in this example, the rear side of the vehicle body. Move (FIG. 4). The clip 10 that has moved to the engaging portion 39 engages with the engaging portion 39 and is sandwiched between the widened portion 35 and the stopper portion 43 so that the roof molding 20 moves in the vertical direction and the length direction. Regulate (slide). In this way, the roof molding 20 attached to the roof R of the automobile has both ends in the length direction of the clip 10 sandwiched between the widened portion 35 and the stopper portion 43. Further, the widened portion 35 and the stopper portion 43 are not easily damaged, and the movement of the molding 20 in the length direction can be suppressed. As a result, it is difficult to generate a gap at the boundary between the window molding W and the roof molding 20, deformation of the window molding W and the roof molding W, and the like can be improved.
[0028]
Further, when the roof molding 20 is fixed to the clip 10, the side walls 11 of the clip 10 are temporarily expanded by the widened portion 35 by the slide of the roof molding 20, and the clip in the expanded state 10 is moved to the engagement portion 39 of the roof molding 20 to release the expansion and engage with the engagement portion 39, so that the clip 10 can be fixed smoothly, and the roof molding can be performed smoothly. The roof molding 20 can be attached accurately and reliably without causing damage or the like in the vicinity of the 20 engaging portions 39. The other parts of the roof molding 20 may be other fixed parts (including adhesive) or by contact between the tips of the lips 27 and 27 and the side wall S1 of the concave groove S of the roof R. It is fixed to the concave groove S.
[0029]
【The invention's effect】
As described above, according to the roof molding mounting structure of the present invention, the movement in the length direction of the roof molding is regulated by sandwiching both ends in the length direction of the clip between the wide portion of the roof molding and the stopper portion. Therefore, even when the roof molding is expanded or contracted due to a temperature change, the vicinity of the engaging portion with the clip is hardly damaged, and the roof molding can be held correctly. Furthermore, the sliding at the time of engaging the roof molding with the clip is easy, and in addition, the roof molding can be attached accurately and reliably without being easily damaged near the engaging portion of the roof molding. Furthermore, since it is not necessary to attach the bracket to the roof molding by caulking as in the prior art, the attachment is simplified and the cost is reduced.
[0030]
Furthermore, according to the present invention, the roof molding can be prevented from being damaged in the vicinity of the engaging portion with the clip even by the expansion and contraction of the roof molding due to a temperature change as described above, and the displacement in the length direction of the roof molding can be suppressed. Even when the roof molding is mounted so that the end of the molding is in contact with the wind molding, there is no possibility of problems such as a gap between the wind molding and the roof molding, or the wind molding or roof molding being lifted. The appearance of the roof part can be improved.
