  A joint 46 between the other end 36 b of the outer center 36 and one end 38 a of the outer lower 38 forms a rib that protrudes into a space surrounded by the outer panel 39 and the inner panel 40. The joint 46 is formed substantially parallel to the joint 48 between the other end 38 b of the outer lower 38 and the one end 40 a of the inner panel 40. A hole 38c is formed in the vehicle width direction central portion of the outer lower 38, and a grommet 60 having a positioning groove 58 having a long hole shape elongated in the vertical direction is formed in the hole 38c as shown in FIG. Is fitted. The positioning groove 58 is formed in the vicinity of the upper portion of the rear window panel 22 to which the glass 16 is attached. The guide pin 24 attached to the glass 16 is engaged with the upper end of the glass 16 with respect to the rear window panel 22. It is for positioning a part. The joint portion 48 is connected to the rear window panel 22 at both sides in the vehicle width direction (see FIG. 2), and pins 28a and 28b disposed on the glass 16 are fitted into the joint portion 48. Thus, holes 26a and 26b for positioning the upper end side of the glass 16 to the rear window panel 22 are formed.

  As shown in FIG. 5, a hole 52 is formed in the joint portion 44, which is the vehicle rear end portion of the outer upper 34, with which the protrusion 50 on the upper part of the garnish 20 is engaged. A rubber packing 54 that comes into contact with the glass 16 is attached to the lower part of the garnish 20. A circuit box 56 for the stop lamp 18 is disposed on the surface of the garnish 20 on the rear spoiler 14 side.

  The rear spoiler 14 of the present embodiment is basically configured as described above. Next, the manufacturing procedure of the rear spoiler 14 and its effect are demonstrated.

  First, by pressing a sheet metal, the outer panel 39 is divided into three pieces, that is, an outer upper 34, an outer center 36, and an outer lower 38, and a single inner panel 40 is formed.

  In this case, the outer panel 39 is divided into a shape in which the outer upper 34 and the outer center 36 do not have an inverse shape, and the divided outer upper 34 and the outer center 36 are combined to form an inverse shape. Further, by adding the outer lower 38 to the outer upper 34 and the outer center 36 and dividing the outer panel 39 into three pieces, even the large outer panel 39 can be formed very easily. Therefore, by combining the outer panel 39 and the inner panel 40, the large rear spoiler 14 having desired aerodynamic characteristics can be manufactured easily and with high accuracy.

  Next, the rear spoiler 14 is assembled by joining the outer upper 34, the outer center 36, the outer lower 38, and the inner panel 40 by spot welding or the like at the joint portions 42, 44, 46, and 48. The assembled rear spoiler 14 is fixed between a rear rail portion (not shown) of the roof 12 and the upper portion of the rear window panel 22.

  In this case, the joint 46 between the other end 36b of the outer center 36 and the one end 38a of the outer lower 38 is substantially parallel to the joint 48 between the other end 38b of the outer lower 38 and the one end 40a of the inner panel 40. Formed. Accordingly, since the joining portions 46 and 48 have different joining positions but the joining directions are substantially the same, for example, when joining the joining portions 46 and 48 using a joining means such as a welding robot, the joining operation is performed. It can be done easily and quickly. As a result, the rear spoiler 14 can be efficiently manufactured.

  In addition, there is a concern that the rigidity of the outer panel 39 is reduced by dividing the outer panel 39 into three parts. However, since the joint 46 between the outer center 36 and the outer lower 38 forms a rib that protrudes into a space surrounded by the outer panel 39 and the inner panel 40, sufficient rigidity of the rear spoiler 14 is secured by this rib. .

  Moreover, since the rear spoiler 14 is formed of a sheet metal that is the same material as the vehicle body, the rear spoiler 14 can be coated together with the vehicle body after being fixed to the vehicle body. In this case, since the vehicle body and the rear spoiler 14 can be colored using the same coating material, a color matching process is not required, and the rear spoiler 14 having a desired color that matches the color of the vehicle body is easily and inexpensively manufactured. be able to.

  Next, an operation of attaching the glass 16 to the rear window panel 22 is performed.

  The operator tilts the glass 16 so that the adhesive 32 does not come into contact with the rear window panel 22, and engages the distal end portion of the guide pin 24 with the positioning groove 58 of the grommet 60 disposed in the outer lower 38 of the rear spoiler 14. (See the direction of arrow A in FIGS. 2 and 3).

  Next, from the state of FIG. 3, the glass 16 is rotated in the direction of arrow B around the tip of the guide pin 24, whereby the pins 28 a to 28 d of the glass 16 are engaged with the holes 26 a to 26 d. The adhesive 32 applied around the glass 16 adheres to the rear window panel 22, and the glass 16 is fixed to the rear window panel 22 (see FIGS. 4 and 5).

  After fixing the glass 16 to the rear window panel 22, the upper protrusion 50 of the garnish 20 is engaged with the hole 52 formed in the joint 44 of the rear spoiler 14, and the lower rubber packing 54 is attached to the glass 16. The garnish 20 provided with the stop lamp 18 is attached.

  In this case, the joint portion 44 between the outer upper 34 and the outer center 36 and the joint portion 46 between the outer center 36 and the outer lower 38 are covered with the garnish 20, and thus cannot be visually recognized from the outside. The guide pins 24 for attaching the glass 16 to the rear window panel 22 are also covered with the garnish 20. Therefore, the space between the vehicle rear end portion of the outer upper 34 and the glass 16 is covered with the garnish 20, and a good appearance design can be obtained.

  In addition, this invention is not limited to embodiment mentioned above, It can change in the range which does not deviate from the main point of this invention.

  For example, the outer upper 34 constituting the rear spoiler 14 has a shape in which the rear of the vehicle is largely bent downward, but the outer upper 34 has a substantially linear shape, and the outer center 36 is joined to the vehicle rear end of the outer upper 34. The one end portion 36a side which is the rear end portion may be bent upward and joined to the other end portion 34b of the outer upper 34. Moreover, if the vehicle body and the rear spoiler 14 are formed of the same metal material, it is not always necessary to perform coating simultaneously, and even in different processes, color matching can be easily performed by using the same coating material. It can be carried out.
