Description

[Detailed description of the invention] Regarding boilers.

BACKGROUND ART AND PROBLEMS When a car travels at high speed, a buoyant force is generated by the air, making it impossible for the driving force of the car to be effectively transmitted to the ground through the tires.

Therefore, a method has been adopted in which a rear spoiler is attached to the surface of the rear part of the automobile, for example, the trunk, to generate a restraining force and cancel out the buoyancy force.

However, conventional rear spoilers must be secured by tightening screws from the back side of the trunk of the car, so the installation work must always be done with the trunk open. That is, the trunk is supported in an inclined state, the rear spoiler must be placed on the surface of the supported trunk, and screw tightening work must be performed while the rear spoiler is supported. Therefore, the work requires a plurality of workers and is a complicated work.

On the other hand, conventional rear spoilers have a fixed length, so they can be manufactured in various lengths and kept in stock depending on the width of the vehicle, more precisely the width of the vehicle. Improvements were desired in terms of inventory management, etc.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a rear spoiler for an automobile that can be easily attached to a trunk regardless of the width of the trunk.

Means for Solving the Problems In order to solve the problems above, the rear spoiler for an automobile according to the present invention includes a base member fixed to the inner wall of the main body,
a substantially wedge-shaped member that moves along the tightening force transmission axis on the surface of the base member; a receiving portion that is movable in the vertical direction and is in contact with the wedge-shaped member at one end; The present invention is characterized in that a connecting member having an automobile trunk edge receiving portion, and an attachment device are housed in both ends of the main body.

Further, it is preferable that the main body of the rear spoiler consists of a fixed wing in the center and movable wings on both sides.

The rear spoiler for an automobile having the above structure is placed on the surface of the trunk of the automobile, and only the trunk elan receiving portion of the connecting member of the mounting device is placed on the back side of the trunk.

Therefore, since the tightening force transmission shaft is arranged on the front side of the trunk, the tightening force is transmitted to the tightening +1 force transmission shaft when the trunk is closed.

This tightening force is transmitted from the tightening force transmission shaft to the substantially wedge-shaped member. The wedge-shaped member moves along the force transmission axis and is forcibly inserted between the base member and the connecting member, and the tightening force transmitted to the wedge-shaped member becomes a force that pushes up the connecting member. This force is transmitted to the trunk edge receiving portion of the connecting member and acts as a tightening force between the rear spoiler and the trunk.

In addition, the main body of the rear spoiler has movable wings on both sides that slide around a fixed wing in the center, allowing the length to be adjusted to suit the width of the trunk.
