A ventilation device for a vehicle includes a frame defining an opening and a closure device that includes at least one closure flap extending in the opening. The ventilation device includes a first section having a first external face and at least a second section having a second external face. The external face of the closure flap is formed by the first external face and by the second external face, the first section and the second section extending in continuity of one another. The first section is joined to the second section in a junction region, with a trimming piece that covers at least the junction region on the external face of the closure flap.

An airflow adjusting apparatus to be provided in a vehicle includes an airflow ejector. The vehicle includes a wheel and a wheel housing including a cavity. The cavity is opened downward and laterally outward of a vehicle body of the vehicle, and houses a portion of the wheel. The airflow ejector is provided, in the cavity, on a front side of the vehicle relative to the wheel. The airflow ejector is configured to eject an airflow that forms a turbulence boundary layer adjacent to a surface of the wheel on a vehicle-widthwise inner side.

A vehicle spat device includes: a spat that rotatably supported by a first rotation shaft and configured to be displaced between a deployment position and a storage position; and a link unit transmitting power of an actuator to the spat. The link unit includes a drive link rotating integrally with a drive shaft when the actuator is driven, and an intermediate link connected to the spat via a second rotation shaft and connected to the drive link via a third rotation shaft. The drive link rotates around the drive shaft between a first position where the spat is disposed at the storage position and a second position where the spat is disposed at the deployment position. In the drive link, the first position is a position rotated from a first neutral position in a first rotation direction.

According to a link mechanism type variable wheel deflector applied to a vehicle, a deflector coupled to a cover plate using a hinge boss as a rotation center can be operated using traveling resistant wind as a driving source, a piston receiving the linear movement of a link shaft by a moment arm rotated with the deflector can unfold the deflector while compressing an elastic member, and an elastic restoring force of the elastic member can be applied to the piston to return the link shaft and the moment arm to fold the deflector, thereby strengthening the repeated durability of the elastic member compared to the rotating motion of the spring, and in particular, the rotating motion and the linear motion can be implemented by the link motion mechanism apparatus connected to the deflector, thereby implementing the high durability performance with the low-cost mechanical structure.

A flow deflecting device includes a flow deflecting body configured to be deployed to a front side of a front wheel and configured to be retracted in a vehicle body; a rotational mechanism, whereby the flow deflecting body is rotatable in an engaged state at the rotational mechanism; and a limiting mechanism, whereby rotation of the flow deflecting body is limitable in an engaged state at the limiting mechanism. In a case in which the flow deflecting body in a deployed position is acted upon by an external force, engagement with the rotational mechanism is released, and the flow deflecting body is rotated in the retraction direction in the engaged state at the limiting mechanism. In a case in which the flow deflecting body in a retracted position is acted upon by an external force, engagement with the limiting mechanism is released, and the flow deflecting body is rotated in the retraction direction in the engaged state at the rotational mechanism.

An active air dam notification method includes, among other things, transitioning an air dam of a vehicle between a first position and a second position, and providing an alert to a user. The alert indicates that the air dam is transitioning. The air dam is vertically higher when the air dam is in the first position than when the air dam is in the second position.

The present disclosure provides a vehicle spoiler, which can stabilize the airflow passing through the vehicle, thereby improving the aerodynamic performance. The vehicle spoiler includes a plurality of skin portions arranged along the front-rear direction of the vehicle and overlapping each other in sequence in the front-rear direction of the vehicle; and a plurality of movable portions respectively supporting the plurality of skin portions and movable in the front-rear direction of the vehicle. The plurality of skin portions change the overall length in the front-rear direction of the vehicle through movement of at least one of the plurality of movable portions in the front-rear direction of the vehicle. Moreover, the plurality of skin portions are maintained to overlap in the movable range of the plurality of movable portions.

A deflector device includes a deflector body that is configured to be deployed in front of a front wheel of a vehicle by being rotated in a deploy direction and to suppress airflow onto the front wheel, and that is configured to be stowed in a body of the vehicle by being rotated in a stow direction; a drive member that is configured to transmit drive force; and a transmission member that is provided with a projection that protrudes in a radial direction thereof and that is configured to be engaged with the drive member such that drive force from the drive member is transmitted to the transmission member and the deflector body is rotated.

The disclosure provides a vehicle lower structure, which is used to change the air resistance of the vehicle bottom. The vehicle lower structure includes: a plurality of strakes, disposed in front of a wheel when viewed from a front of the vehicle; and at least one strake of the plurality of strakes, disposed to be movable in an up-down direction. The vehicle lower structure includes: a plurality of strakes, disposed in front of a wheel when viewed from a front of the vehicle; and at least one strake of the plurality of strakes, disposed to be movable in a front-rear direction.

A deflector device having a deflector body that is configured to be deployed in front of a front wheel of a vehicle by being rotated in a deploy direction and to suppress airflow onto the front wheel, and that is configured to be stowed in a body of the vehicle by being rotated in a stow direction; a rotation shaft that is configured to rotate the deflector body by rotation of the rotation shaft; and a transmission member that is configured to transmit drive force to the rotation shaft to rotate the rotation shaft, and to be moved, when an external force has acted on the deflector body such that the deflector body is rotated in the stow direction from a stowed position, by movement of the rotation shaft in an axial direction being limited.
