CONSTITUTION:An about L-shaped groove 15, formed with a lateral groove part 15a, communicated with the front edge of a body part 10a, and a longitudinal groove 15b, extended above a parting line 14 between a trunk lid 2 and a rear fender 3 and connected to the rear end of the rear spoiler 10, is provided in the bottom of the rear spoiler 10.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a rear spoiler for an automobile.

(Prior Art) A rear spoiler has the effect of rectifying airflow at the rear of an automobile and reducing lift, and is usually attached to a rear opening/closing body, such as a trunk lid. In that case, conventional rear spoilers were often installed only on the trunk lid, but recently, in order to improve the appearance and improve the rectification effect, spoilers that overhang from the trunk lid to the rear fender have become widely available. There is. Fifth
The figure shows an example of such a rear spoiler.The rear spoiler 1 is made of a urethane resin alone or has an insert panel built into the urethane resin.The main body part 1a is attached to the trunk lid 2 using adhesive tape. and overhang parts 1b provided at both ends thereof and covering the top of the rear fender a. A predetermined gap 4 is formed between this overhang portion 1b and the rear fender 8 to prevent interference when the trunk lid 2 is closed, as shown in FIG. 6 showing the cross section taken along the line ■-■ in FIG. In addition, due to aerodynamic characteristics, many have a shape that protrudes forward from the front edge of the front Rt main body portion 1a. (Refer to Japanese Utility Model Application Publication No. 59-67382) (Problem to be Solved by the Invention) However, in such a conventional rear spoiler, the front edge of the overhang portion 1b that covers the rear fender 3 protrudes forward, so that the trunk Rainwater, car wash water, etc. tend to accumulate on the rear edge of the lid, and this water collects sand, wax, etc. between the top surface of the trunk lid and the front edge of the rear spoiler body, and damages the paint film of the trunk lid. In addition, there is the problem of corrosion that completely reduces the rust prevention performance, and the high rigidity of the overpart ring part.
To prevent the over/1 ring from strongly interfering with the rear fender and damaging the paint film when the trunk lid is closed, the gap between the two is set to be quite large, resulting in a decline in appearance quality and aerodynamic characteristics. There was a problem in that the overhang part interfered with cleaning the dirt between it and the rear fender.

It is an object of the present invention to solve these problems in conventional rear spoilers.

(Means for solving the problem) In order to achieve this purpose, the rear spoiler of the present invention has the following features:
It has an overhang part covering the upper part of the rear fender at both ends of the main body part which is attached to the upper surface of the rear edge of the rear opening/closing body of the vehicle body,
A rear spoiler 1 is formed in such a shape that the front edge of the overhang part projects forward from the front edge of the main body part, and a lateral groove part continuous to the front line of the main body part is provided on the bottom surface of the rear spoiler, and a lateral groove part continuous with the front line of the main body part, and the opening/closing body. This feature is characterized by the provision of an abbreviated drainage groove consisting of a vertical groove portion that passes over the parting line between the rear spoiler and the rear fender and connects to the rear end of the rear spoiler.

(Function) According to this configuration, even in a rear spoiler in which the front edge of the engine part protrudes forward from the front edge of the main body, water such as rainwater, car wash water, etc. collected on the front surface of the rear spoiler flows into the drain channel. The water is guided onto the parting line by the horizontal groove and is discharged rearward by this parting line and the vertical groove of the drain, so that water does not accumulate on the rear edge of the rear opening/closing body of the vehicle. .

Further, by providing the drainage groove as described above, the overhang portion has upward flexibility.

(Example) The rear spoiler of the present invention will be described in detail below with reference to the drawings.

1 and 2 are diagrams showing an embodiment of the present invention. This rear spoiler 10 is made of urethane resin foam (f)), and its main body 10a is relatively inside the rear spoiler (f) as shown in FIG. It has a built-in insert panel 1 which is a highly rigid plate-like body, and this insert panel]
It is attached to a rear opening/closing body, for example, a trunk lid 2, by a bolt 12 embedded therein and a nut 3. An overhang portion 10k) that covers the rear fender 3 is formed at both ends of the main body portion 10a. This overhang] The leading edge of ObO is an intangible part that extends in the horizontal direction] A shape that projects forward in a gentle arc from the leading edge of Oa (!:
It's sitting. The bottom of the rear spoiler IO is the main body IU.
A horizontal groove portion 15a that continues to the front edge of the rear spoiler 10 and a vertical groove portion 15 that passes on the parting line 14 between the trunk lid 2 and rear fender 3 (!) and the rear end E of the rear spoiler 10.
An abbreviated drain groove 15 consisting of b is provided.

This vertical groove portion 15b is located on the rear fender a as shown in FIG.
You can also strain it so that there is a large bulge on the top.

Next, the function of this rear spoiler will be explained. Water such as rainwater and car wash water on the trunk lid 2 is collected at the front of the rear spoiler 10 because the overhang part 10b of the rear spoiler 10 protrudes forward, but water is collected at the front of the rear spoiler 10 by the drainage groove 15 provided on the bottom of the rear spoiler 10. Since the water is discharged rearward along the rear spoiler 14, water does not accumulate on the front surface of the rear spoiler 10, thereby preventing water from accumulating on the front surface of the rear spoiler 10.
Since sand, wax, etc. do not get stuck between the upper surface of the trunk lid 2 and the front edge of the main body part 10a, rusting of the trunk lid 2 and deterioration of the appearance quality due to scratches on the paint film are prevented. Furthermore, by providing the drainage groove 15 in the rear spoiler 10, the rigidity of the overhang part 10b on the trunk lid of the rear spoiler 10 can be reduced, so that when the trunk is suddenly closed, as shown by the broken line I in FIG. This part can be bent upwards. As a result, the impact force applied to the rear fender is alleviated, which narrows the gap between the over/S wing part and the rear fender, improving the appearance of this part and improving the aerodynamic characteristics. .

In addition, since the overhang part 10b is easily bent, even if sand, wax, etc. become clogged between it and the rear fender, it can be cleaned by bending upward to the hang part 1 (1'). This also improves cleaning performance.

(Effects) As detailed above, according to the rear spoiler of the present invention, water does not accumulate at the rear spoiler portion at the rear edge of the rear opening/closing body of the vehicle body, so the rust prevention performance and appearance quality of the rear opening/closing body of the vehicle body are improved, and the rear spoiler Since it is possible to narrow the gap between the overhang part on the rear fender and the rear fender, this has the effect of improving the appearance and aerodynamic characteristics of this part, as well as improving the cleanability.
