The bracket can be fastened to the roof side portion, and the assembled state of the mounting bracket can be confirmed.

Hereinafter, the present invention will be described in detail based on illustrated embodiments.
[First embodiment]
FIG. 1 is a perspective view of an essential part of a roof side portion mounting structure for an automobile according to a first embodiment of the present invention, FIG. 2 is a cross-sectional view taken along line AA of FIG. 1 in the first embodiment, and FIG. 1 is a cross-sectional view taken along line BB in FIG. 1 in the embodiment, and FIG. 4 is a cross-sectional view taken along line CC in FIG. 1 in the first embodiment.
1 to 4, 1 is a vehicle body, 2 is a roof of the vehicle body 1, 4 is a roof panel constituting the roof 2, 5 is a roof side outer panel, 6 is a roof side inner panel, and 7 is a roof side outer panel 5. This is a reinforcement provided between the roof side inner panel 6 and the roof side inner panel 6.
As shown in FIG. 2, a groove 3 with an opening facing upward is formed along the vehicle front-rear direction at the joint 8 between the roof panel 4, the roof side outer panel 5, the reinforcement 7 and the roof side inner panel 6. It is extended.

On the roof 2, roof rails 9 for mounting a carrier for loading luggage are fixed to the left and right roof side portions by means described later (FIG. 1 shows only one roof rail 9). . That is, the pair of left and right roof rails 9 extend along the vehicle front-rear direction of the roof 2, and a load mounting rack is attached between the pair of left and right roof rails 9.
The roof rail 9 is fixed to the roof side portion by bolts 14 at a plurality of locations in the vehicle front-rear direction (five locations in this embodiment), and both ends thereof are brackets 22 erected at the bottom of the groove 3. It is attached detachably by inserting the clip 21 into the hole 22a. In addition, the roof rail 9 includes a main body 10 having a special shape, which will be described later, and a bolt intake 16 that is closed by a cap 17 is formed in the main body 10.

As shown in FIGS. 2 to 4, the joining portion 8 overlaps the end portion of the roof panel 4 with the end portions of the roof side outer panel 5, the lean reinforcement 7 and the roof side inner panel 6. The parts are joined by spot welding S.
On the other hand, a plurality of bolt through-holes 18 penetrating the joint 8 are provided at the bottom of the groove 3 provided in the joint 8, and an inner portion of each bolt through-hole 18 of the joint 8. The nut 20 is fixed to the lower surface of each by welding.

The main body 10 of the roof rail 9 is formed in a box-shaped cross section having a closed space 11 inside. The left and right side edges of the lower surface 12 of the main body 10 are provided with lip portions 13 a and 13 b for the left and right seals of the roof rail 9 projecting obliquely downward and outward. The roof rail 9 is provided with a lip portion of the main body 10. 13 a and 13 b are attached to the roof 2 in a state where the roof side outer panel 5 and the roof panel 4 positioned on the left and right outer sides of the groove 3 are brought into contact with each other to prevent water from entering the groove 3.
Further, the lower wall 9b facing the closed space 11 of the main body 10 is provided with a bolt insertion port 15 through which the bolt 14 is inserted in an upper portion of the bolt through hole 18 and faces the closed space 11. An intake port 16 for taking in the bolt 14 is provided at a position above the bolt insertion port 15 in the lower wall 9b. A cap 17 that opens and closes the intake port 16 is detachably attached.
In addition, a cylindrical spacer 19 having a through hole 19a for inserting a bolt is interposed between the bottom of the groove 13 and the lower surface 12 of the lower wall 9b of the main body 10. The upper end portion is fixed to the main body portion 10 of the roof rail 9 by press-fitting the upper end portion into the bolt insertion port 15. For this reason, the upper end portion of the spacer 19 has a smaller diameter than the other portions and is formed in a size that can be press-fitted into the bolt insertion port 15.

  With this configuration, the bolt 14 is inserted into the closed space 11 from the intake port 16 by removing the cap 17, and passes through the bolt insertion port 15, the through hole 19 a of the spacer 19, and the bolt through hole 18 of the joint portion 8. The nut 20 is screwed together. As a result, the roof rail 9 is firmly fixed to the roof 2 by the bolts 14 and the nuts 20 via the spacers 19. Reference numeral 24 denotes an interior panel that covers the vehicle interior side of the roof 2.

Further, two attachment portions (see FIG. 1) at both front and rear end portions of the roof rail 9 are formed by bosses 9c protruding from the upper wall 9a of the main body portion 10 of the roof rail 9 into the closed space 11, as shown in FIG. By attaching the clip 21 to the hole 23 and pushing the clip 21 into the hole 22a of the bracket 22 standing in the space 11, the front and rear ends of the roof rail 9 are fixed to the roof side part. .
As a result, the front and rear ends of the roof rail 9 can be simply operated by pushing the clip 21 attached to the hole 23 of the boss 9c of the main body 10 in the roof rail 9 into the hole 22a of the bracket 22 standing in the closed space 11. The part can be securely fixed to the roof side part.

  Thus, according to the first embodiment of the present invention, at the joint 8 between the roof 2 and the roof side panels 5, 6, 7, the joint 8 is formed at the bottom of the groove 3 extending in the vehicle longitudinal direction. And a nut 20 is fixed to the inner part of the bolt through hole 18 of the joint 8 by welding or the like, and the bolt 14 is screwed into the nut 20 from the outside of the vehicle body 1 through the bolt through hole 18. Since the roof rail 9 is fastened to the roof side portion by joining, the roof rail 9 can be removed without removing the interior panel 24 such as the interior trim by simply screwing the bolt 14 into the nut 20 on the joint 8 side. It can be fastened to the roof side part, and the attaching / detaching work of the roof rail 9 to the roof side part becomes easy.

Further, according to the first embodiment of the present invention, the roof rail 9 is formed in a box-shaped cross section having a closed space 11 therein, and the bolt 14 is incorporated into the upper wall 9a of the roof rail main body portion 10 having the box-shaped cross section. Since the intake port 16 is provided, the lower wall 9b of the main body 10 is provided with a bolt insertion port 15 for inserting the bolt 14, and the cap 17 that can be opened and closed is detachably attached to the intake port 16. When the cap 17 is removed from the inlet 16, the bolt 14 is taken from the inlet 16 and screwed into the nut 20 through the bolt insertion port 15, the through hole 19 a of the spacer 19, and the bolt through hole 18 of the joint 8. Thus, even the roof rail 9 having a box-shaped cross section can be easily fastened to the roof side portion from the outside without removing any interior panel 24 such as an interior trim. In addition, since the bolt 14 is disposed in the closed space 11 covered with the cap 17, the external appearance is improved because it is not exposed to the outside.
In addition, since a spacer 19 having a through hole 19a for inserting a bolt therein is interposed between the bottom of the groove 13 and the lower surface 12 of the lower wall 9b of the roof rail body portion 10, the depth of the groove 3 depends on the vehicle type. Even when the distances are different, the roof rails 9 can be replaced simply by replacing the spacers 19, and the roof side portion mounting structure can be shared by multiple vehicle types.
