As shown in the figure, the spoiler 11 is made of a thermoplastic resin (for example, polypropylene) and extends in the vehicle width direction to form a design surface 12a, and is disposed at a predetermined position in the vehicle width direction. A plurality of (for example, nine) thin portions 13 and the reinforcing portions 14 are integrally formed by injection molding. In addition, the thinned thin part 13 is for connecting the main body part 12 and the reinforcing part 14, and is arranged at substantially equal intervals in the vehicle width direction.

  As shown in FIG. 3, the main body 12 includes an upper wall portion 21 that extends in the vehicle front-rear direction, a rear wall portion 22 that extends continuously downward from the rear end of the upper wall portion 21, and the rear wall portion 22. The lower wall portion 23 extends continuously from the lower end of the vehicle so as to be folded forward and is formed into a substantially arcuate cross section. The rear wall portion 22 and the lower wall portion 23 project from the inner wall surface 24 on the opposite side of the design surface 12a so as to face both ends of the reinforcing portions 14 (thin wall portions 13) in the vehicle width direction. A pair of ribs 25 are formed.

  Each reinforcing portion 14 is connected to the front end of the lower wall portion 23 via a thin portion 13. The reinforcing portion 14 has a vertical wall portion 41 continuing to the thin wall portion 13 and an extending wall 42 extending obliquely with respect to the vertical wall portion 41 and is formed in a substantially U-shaped cross section. And the reinforcement part 14 has the base part 14a which protrudes in the shape of a vehicle from the vehicle width direction center part of the corner | angular part which the vertical wall part 41 and the extension wall 42 form, and the transparent part which penetrates the center part of this base part 14a. It has a hole 14b. The spoiler 11 includes a connecting wall 15 that connects between the extension walls 42 of three adjacent reinforcing portions 14 excluding both ends and the center of the plurality of reinforcing portions 14.

Next, the coupling structure of the main body portion 12 and the reinforcing portion 14 will be further described.
As shown in FIG. 3, the upper wall portion 21 of the main body portion 12 has a vehicle lower direction facing the central portion in the vehicle width direction of each reinforcing portion 14 from an inner wall surface 26 on the opposite side of the design surface 12 a. A locking claw 27 projecting from is formed. The locking claw 27 has a column part 27a standing on the inner wall surface 26 and a claw part 27b protruding from the lower end of the column part 27a toward the vehicle front side. Each rib 25 of the main body portion 12 is formed with a convex portion 29 as a main body portion side engaging portion that protrudes from the middle portion of the front end in the vertical direction toward the vehicle front side.

  On the other hand, the extending wall 42 of each reinforcing portion 14 has a locking hole 43 that penetrates in the vehicle vertical direction (plate thickness direction) facing the locking claw 27 on the rotation trajectory around the thin portion 13. Is formed. As the main body 12 and the reinforcing portion 14 rotate relative to the main body 12 and the reinforcing portion 14 around the thin-walled portion 13, the locking claw 27 (column portion 27 a) is loosely inserted into the locking hole 43, and the claw portion 27 b. Are connected to each other by being locked to the front edge portion of the locking hole 43. The extension wall 42 is formed with a flat elastic piece 44 that protrudes from the rear end of the locking hole 43 toward the vehicle front side. The elastic piece 44 is for restricting relative movement (positional deviation) of the main body 12 and the reinforcing portion 14 in the vehicle front-rear direction, and with the relative rotation of the main body 12 and the reinforcing portion 14 around the thin portion 13. The locking claw 27 loosely inserted into the locking hole 43 is elastically deformed by being pressed against the rear end surface of the locking claw 27 and released from the locking claw 27 locked by the locking hole 43 to be elastically restored. It contacts or approaches the rear end face of the locking claw 27 (column part 27a). Further, the vertical wall portion 41 of each reinforcing portion 14 has a reinforcing portion side engaging portion that penetrates in the vehicle front-rear direction (plate thickness direction) facing the convex portion 29 on the turning locus around the thin portion 13. A recess 45 is formed.

The main body portion 12 and the reinforcing portion 14 are relatively rotated around the thin-walled portion 13 until the inner wall surface 26 abuts or approaches the inner wall surface 26. At this time, when the locking claw 27 is locked to the locking hole 43 in the above-described manner, the main body portion 12 and the reinforcing portion 14 are coupled, and the elastic piece 44 contacts or approaches the locking claw 27. Thus, the relative movement (position shift) of the main body portion 12 and the reinforcing portion 14 in the vehicle front-rear direction is restricted.

  At the same time, the front end surface of the rib 25 and the reinforcing portion 14 (vertical wall portion 41) come into contact with or approach each other while the convex portion 29 is inserted into the concave portion 45. The tip end portion of the convex portion 29 penetrating the concave portion 45 is thermally deformed so as to be expanded in the subsequent heating step, thereby forming a substantially pan-shaped lid portion 29a.
