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 rain and deflects it along the five sides of the back door glass, and has a wiping function that blows away raindrops, splash, and dust adhering to the five sides of the back door glass, ensuring sufficient rearward visibility for the occupants. It's like this.

Problems to be Solved by the Invention Although the function of wiping the back door glass 5 by the wind guide plate 6 is obtained, a lift force is generated at the rear of the vehicle body because the wind is deflected diagonally downward, and this tendency is particularly noticeable when driving at high speeds. This causes a problem that worsens driving stability.

Therefore, the present invention not only allows the surface of the back door glass and rear window glass to be wiped away by the wind when driving in the rain, but also increases the ground contact force of the rear wheels in non-rainy weather, and functions as a rear spoiler to reduce air resistance. The purpose of the present invention is to provide a rear air guide device for an automobile that can improve the anti-theft properties of the air guide plate.

Means for solving the problem A wind guide plate extending in the vehicle width direction is rotatably attached to the upper rear part of the vehicle body via a hinge member, and
A rotation mechanism is provided between the wind guide plate and the vehicle body to rotate and hold the wind guide plate in a position where the wind is directed diagonally upward and a position where the wind is directed diagonally downward along the rear surface of the vehicle body. and at least one of the connection parts between the air guide plate and the hinge member or the rotation mechanism is provided with a required opening angle in a substantially V-shape in the front and rear direction on the back surface of the air guide plate. It is recessed to form oblique front and rear mounting surfaces, one of which faces the vehicle body at each of the baffle plate operating positions.

Function: By rotating the wind guide plate to any operating position using the rotating mechanism, the wind is directed diagonally downward along the rear of the vehicle body, and can be used as a dirt prevention device for back door glass and rear window glass. It functions as a rear spoiler by directing the wind diagonally upward. In addition, at each operating position of the air guide plate, one of the front and rear mounting surfaces formed on at least one of the connection parts between the air guide plate and the hinge member or the rotation mechanism faces the vehicle body side, and the air guide plate is Make removal impossible.
