れている。2. Description of the Related Art When a passenger car or the like travels at a high speed, a lift is generated in the vehicle body due to a pressure difference between an airflow passing through an upper portion of the vehicle body and an airflow passing through a lower portion of the vehicle body. For this reason, in a passenger car or the like, a countermeasure is taken to reduce the lift by generating a down force on the running vehicle body by additionally mounting a spoiler on a lower front portion or an upper rear portion of the vehicle body.

「リアスポイラ」が開示されている。On the other hand, in a vehicle such as a wagon type or a one-box type in which a rear window glass is steeply inclined from the rear end of the roof, an airflow moving rearward along the roof moves as it is to the rear of the vehicle. Dust, rainwater, snow, etc. on the outer surface of the rear window glass.
(Hereinafter referred to as “adhered matter”) easily adheres. For this reason, for example, Japanese Patent Application Laid-Open Nos. 8-198149 and
Japanese Patent Application Publication No. 198150 discloses an attachment of the deposit to the rear window glass by branching a part of an air flow moving rearward along the upper surface of the roof so as to move along the rear window glass. A "rear spoiler" that functions to prevent the occurrence of a spoiler is disclosed.

物の付着を防止するものである。That is, the rear spoilers disclosed in the above publications are installed so as to protrude appropriately above the roof of the vehicle body and to be appropriately separated from the outer surface of the rear window glass. Accordingly, the airflow moving rearward along the roof upper surface is the first airflow moving substantially horizontally rearward along the spoiler upper surface, and the second airflow moving rearward downward along the rear window glass from the front surface of the rear spoiler. 2
It is branched into an air flow, and by using the “air flow effect” by the second air flow, the adhesion of the deposit to the rear window glass is prevented.

Even if it is possible to suitably prevent adhesion of extraneous matter to the outer surface of the rear window glass, there is an inherent problem that the spoiler's original function of reducing lift is rather impaired. Also, since the rear spoiler protrudes upward from the upper surface of the roof, air resistance
(CD value) is increased to cause deterioration of fuel efficiency and generation of wind noise, but also point out difficulties such as impairing the body design.

ようになっている。The spoiler 10 of the embodiment makes the airflow moving toward the rear of the vehicle body 20 along the upper surface of the roof 22 during traveling substantially horizontally along the upper surface (the upper surface of the spoiler) 16 of the main body 12. The air flow is branched into a first air flow that moves and a second air flow that moves backward from the air circulation space 26 along the rear window glass 24.
The first airflow reduces the lift generated in the vehicle body 20 and the second airflow prevents the attached matter from adhering to the outer surface of the rear window glass 24.

To Therefore, first, terms used for describing the present invention will be described. (a) Vehicle speed ratio: a ratio of the flow velocity V 1 of the air flow moving along the roof 22 to the flow velocity V 2 of the second air flow, and V 2 / V 1 × 1
Calculated as 00 (%). (b) Projection amount H: upper surface 16 of main body 12 as shown in FIG.

(c) Inclination angle A: As shown in FIG. 5, when the main body 12 of the spoiler 10 is rotationally displaced about the rotation center O, the angle of the upper surface 16 with respect to the upper surface of the roof 22. (d) Inflow width L 1 : As shown in FIG. 7, the width dimension of the inlet of the air circulation space 26 formed by the rear end surface of the roof 22 and the front surface 18 of the main body 12 of the spoiler 10. (e) Outflow width L 2 : As shown in FIG. 7, the width of the outlet of the air circulation space 26 formed by the outer surface of the rear window glass 24 and the front surface 18 of the main body 12 of the spoiler 10.

なわれてしまう。(Test 1) In test 1, as shown in FIG. 3, a change in the vehicle speed ratio and a change in the lift coefficient when the protrusion amount H of the spoiler 10 with respect to the roof 22 is changed is shown. This is shown in the graph of FIG. As is apparent from FIG. 4, when the protrusion amount H of the front end 16 a of the upper surface 16 of the main body 12 is −10 mm or less, the vehicle speed ratio becomes substantially zero because there is almost no second air flow branched to the air circulation space 26. However, when the protrusion amount H becomes -5 mm, the vehicle speed ratio is reduced to 30 at a stretch.
%, The airflow effect is obtained, and even if the protrusion amount H is further increased, the rate of increase in the vehicle speed ratio (that is, the increase in the speed of the second airflow) does not change significantly. On the other hand, the lift coefficient is substantially zero until the protrusion amount H is zero,
When the protrusion amount H is equal to or more than +5 mm, the spoiler suddenly increases. When the upper surface 16 of the spoiler 10 protrudes even slightly from the roof 22, the spoiler's original function of reducing lift is impaired.

It has been found that it is desirable to set the protruding amount H in the range of -5 mm to 0 mm in order to achieve both the function of preventing protrusion. That is, the front end 16 of the upper surface 16 of the main body 12 in the spoiler 10
a is required to be at least lower than the upper surface of the roof 22.

都合が発生してしまう。(Test 2) In test 2, as shown in FIG. 5, the change in the vehicle speed ratio and the change in the lift coefficient when the inclination angle A of the upper surface 16 of the spoiler 10 with respect to the roof 22 is changed is measured. The measurement results are shown in the graph of FIG. As is clear from FIG. 6, the inclination angle A of the upper surface 16 is 180 degrees or less.
When the vehicle is in the rearwardly rising state, the vehicle speed ratio becomes 30% or more, so that an airflow effect is obtained. As the inclination angle A decreases, the vehicle speed ratio gradually increases. On the other hand, with respect to the lift coefficient, when the inclination angle A becomes 180 degrees or less, if the inclination angle A is reduced, it becomes smaller in proportion to this, which means that the lift can be suitably reduced. However, the inclination angle A
Is less than 135 degrees, the air resistance of the spoiler 10 itself greatly increases, and disadvantages such as deterioration of fuel efficiency and generation of wind noise are generated.

It has been found that it is desirable to set the inclination angle A in the range of 135 to 180 degrees in order to achieve both the function of preventing the rotation and the angle of rotation.

The changes in the vehicle speed ratio and the lift coefficient are measured, and the measurement results are shown in the graph of FIG. As is clear from FIG. 8, the ratio L 2

On the other hand, regarding the lift coefficient, there is almost no change even if the ratio L 2 / L 1 is changed.
The ratio of the inlet width L 1 and the outflow width L 2 means that little effect on lift coefficient.

In particular, in the spoiler 10 of the embodiment, as described in (1) above, since the protrusion amount H of the front end portion 16a of the upper surface 16 of the main body portion 12 is set to -5 to 0 mm, the front side of the main body portion 12 is And does not protrude upward at all, and the deterioration of fuel efficiency and the generation of wind noise due to an increase in air resistance can be suitably avoided, but the vehicle body design is not hindered.

However, by making the rear end portion of the main body 12 curved, the increase in the air resistance can be minimized.
