時にはこの傾向が著しくなる。BACKGROUND TECHNOLOGY In the case of automobiles, for example, as shown in Japanese Utility Model Application Publication No. 13939/1980, a method is used to blow away raindrops, splash, dust, etc. adhering to the back door glass or rear window glass to ensure rearward visibility. It is known that a wind guide plate is disposed on the upper rear side of the vehicle body to deflect the wind flowing along the roof panel surface so that it flows along the back door glass or rear window glass surface. This will be explained in detail by taking as an example a car equipped with a back door as shown in FIGS.
6 is a wind guide plate arranged in the vehicle width direction on the upper rear side of the vehicle body, specifically, on the upper side of the back door frame 4;
This baffle plate 6 has leg portions 7 integrally molded on both sides, and the leg portions 7 are fixed to the backdoor frame 4 by, for example, welding. This baffle plate 6 is disposed approximately parallel to the back door 2, and its upper end protrudes slightly above the surface of the roof panel 3, so that a portion of the airflow flowing along the surface of the roof panel 3 when the vehicle is traveling. It captures the air and deflects it along the five sides of the back door glass, and has a wiping function that blows off raindrops, splash, dust, etc. adhering to the five sides of the back door glass, ensuring sufficient rearward visibility for the occupants. However, since the wind is deflected diagonally downward, a lift force is generated at the rear of the vehicle body, and this tendency is particularly noticeable when driving at high speeds.

る。 Here, regardless of whether the baffle plate 10 is in the aforementioned spoiler action position S or the wiping action position D, the axis O 1 of the drive link 16 and the driven link 19
Since the axis O 2 of the main body is substantially perpendicular to the axis O 2 , the following advantages can be obtained. That is, when the baffle plate 10 is in the spoiler action position S, the baffle plate 10 is subjected to a pressing force P1 in the clockwise direction in FIG. 8 due to the traveling wind.
This pressing force P 1 is applied to the arm 23, links 21, 22
A biasing force is applied to the driven link 19 in the counterclockwise direction in the figure, but this biasing force is applied to the driving link 16 along the axis
O 1 direction, and no rotational moment acts on the drive link 16. On the other hand, the air guide plate 10
When is in the wiping action position D, a counterclockwise pressing force P2 acts on the baffle plate 10, contrary to the above, and acts on the driven link 19 as a clockwise biasing force.
However, in this case as well, the biasing force acts on the drive link 16 in the direction of the axis O1 , and no rotational moment acts on the drive link 16. As a result, even if the baffle plate 10 is in either the spoiler action position S or the wiping action position D, the rotating mechanism 12 does not move due to the wind pressure while the vehicle is running, and the set position of the baffle plate 10 is determined. It is possible. Also,
The drive link 16 and the driven link 19 are connected through a pin 17 and a guide slit 20, and the construction is such that the movement of the driven link 19 near the starting and stopping positions is decelerated, so that very smooth operation can be obtained.

Alternatively, the gear mechanism 15 may be configured by omitting the links 21 and 22 and coaxially fixing a pinion to the driven link 19, and coaxially fixing a sector gear or a pinion to the arm 23 and meshing these gear members. can.

果を有する。Effects of the Invention As described above, according to the present invention, a biasing force acts on the wind guide plate and the driven link in the rotational direction due to the traveling wind pressure at each acting position of the air guide plate, but the driving link has its axis Since no rotational moment is generated by acting in the direction, it is possible to prevent the rotation mechanism from moving due to wind pressure while traveling and to determine the set position of the wind guide plate, improving reliability and quality. can be improved. Moreover, assembly errors and molding errors,
Even if the support points at both ends of the baffle plate and the center of the output shaft of the rotating mechanism are not aligned in a straight line due to dimensional tolerances, the baffle plate will not become stuck when rotating.
This has great effects such as ensuring smooth operation.
