装置を提供することにある。However, the conventional rear lamp rectifier has the following problems. Since the rectifying wall 3 is not at an angle suitable for causing the air flowing along the side wall surface 1 of the vehicle body to follow the surface of the rear lamp 2, the flow separates in the middle of the surface of the rear lamp 2 (A in FIG. 6), The effect of preventing sufficient adhesion of snow, dust and the like is not obtained, making it difficult to visually recognize the rear lamp from behind the vehicle. In addition, flow separation (B in FIG. 6) occurs behind the rectifying wall 3 and noise is reduced. It becomes a problem. SUMMARY OF THE INVENTION It is an object of the present invention to provide a rectifying device for a rear lamp capable of causing more air flowing along a side wall surface of a vehicle body to follow the surface of the rear lamp than before. Another object of the present invention is to provide a rectifying device for a rear lamp which can reduce the separation of the flow behind the rectifying device itself, in addition to the above-mentioned objects.

Since the direction of the surface facing the vehicle body at the rear end of the straightening wall is set such that the tangent of the surface contacts or intersects with the rear lamp, the air flowing along the side wall surface of the vehicle body includes the straightening wall. The air whose flow direction has been changed can be made to follow the surface of the rear lamp more than before. Also, since the rear lamp rectifier is integrally formed with a member that forms all or a part of the surface of the rear lamp,
The number of components can be reduced and the cost can be reduced as compared with a case where the rear lamp is formed separately from a member that forms the whole or a part of the surface. The above (2)
In addition to the above-described operation, the direction of the center line of the wall thickness at the front end of the rectifying wall is such that the direction of the flow flowing along the side of the vehicle body is such that the more upstream, the more distant from the side of the vehicle body. °, 20 ° closer to the side of the vehicle as it goes upstream
Since the outer surface of the front end portion and the outer surface of the rear end portion of the rectifying wall are connected by the outer surface having a smooth curved surface, the separation of the flow behind the rectifying wall can be reduced as compared with the conventional case.

And the rear end outer surface 42b are connected by an outer surface 44 having a smooth curved surface, so that the separation of the flow behind the rectifying wall 40 (B in FIG. 6) can be reduced as compared with the conventional case. Therefore, noise generated due to peeling can be reduced. In addition, the air flow behind the outer surface 44 follows the air flow along the rear lamp 20, and the outer surface 44 serves as a separation area to reduce the flow of air in the air passage 70 and induce separation in the air flow along the rear lamp 20. be able to.

Has a rounded cross section (semicircular cross section) as shown in FIG. 3 or a tapered cross section that slopes away from the vehicle body 30 toward the rear side of the vehicle as shown in FIG. Therefore, the change in the flow of the air escaping out of the air passage 70 can be reduced. Therefore, it is possible to prevent the separation of the air on the outer surface 41b of the front end portion of the flow regulating wall 40.

減できる。According to the rectifying device for a rear lamp according to the first aspect, the direction of the surface of the rear end of the rectifying wall facing the vehicle body is set such that the tangent of the surface contacts or intersects the rear lamp. As a result, of the air flowing along the side wall surface of the vehicle body, the air whose flow direction has been changed by the rectifying wall can be made to follow the surface of the rear lamp more than before. Further, since the rectifier for the rear lamp is integrally formed with the member forming the whole or a part of the surface of the rear lamp, the rectifier for the rear lamp is formed separately from the member forming the whole or a part of the surface of the rear lamp. Compared with this, the number of parts can be reduced, and the cost can be reduced. According to the rectifying device for a rear lamp according to claim 2, in addition to the above effects, the direction of the center line of the wall thickness at the front end of the rectifying wall is more upstream toward the direction of the flow flowing along the side surface of the vehicle body. The outer surface at the front end and the outer surface at the rear end of the rectifying wall are connected by an outer surface consisting of a smooth curved surface, which is within 5 ° away from the side and 20 ° closer to the side of the vehicle body toward the upstream. Therefore, the separation of the flow behind the straightening wall can be reduced as compared with the related art.
