A vehicular aerodynamic device includes first and second links being coupled via first and second engagement members and integrally rotating, thereby transmitting drive force to an aerodynamic member. The first and second engagement members are coupled to the first and second links, respectively, and integrally rotate by engaging with each other, and rotate relative to each other by external force. At least one of a first coupling portion that couples the first link and the first engagement member and a second coupling portion that couples the second link and the second engagement member includes clutch-side and link-side engagement surfaces integrally rotating by engaging with each other. A second gap between the clutch-side and link-side engagement surfaces in a second relative rotation direction is narrower than a first gap between the clutch-side and link-side engagement surfaces in a first relative rotation direction.

Vehicular aerodynamic device

A movable spoiler device provided in a front part of a vehicle body, the movable spoiler device includes: a link mechanism in which a plurality of links are coupled and configured to operate by driving the links by an actuator; a spoiler member connected with one of the plurality of links and being deployable and retractable with respect to the vehicle body by operation of the link mechanism; and a clutch mechanism provided on a driving force transmission path between the actuator and the spoiler member, and configured to block transmission of a driving force when an external force equal to or greater than a predetermined value is applied to the spoiler member with the spoiler member being in a deployed state.

A vehicular straightening device includes: a straightening member disposed in front of a front wheel of a vehicle so as to be movable upward and downward with respect to a vehicle body; a drive unit that moves the straightening member up and down with respect to the vehicle body between a storage position on a vehicle body side and a straightening position where the straightening member protrudes downward from the vehicle body; and a connecting mechanism that connects the straightening member and the drive unit and releases a connection between the straightening member and the drive unit when an external force acts on the straightening member at the straightening position.

Vehicular straightening device

A spoiler device includes a link mechanism and a spoiler member. In the link mechanism, a drive link, an intermediate link, a driven link, and a fixed link are annularly connected. The drive link is driven by an actuator, thereby causing the link mechanism to operate as a four-joint link. The spoiler member is fixed to the intermediate link or the driven link. Any one of the drive link, the intermediate link, and the driven link is configured so as to include, two division links whose one end portions are connected by a connection portion. The two division links are rotatable around the connection portion, and are pressed in rotational directions by a pressing member.

Spoiler device

A movable front spoiler device includes: an actuator including a rotation shaft provided so as to be rotatable forwardly and reversely; a link mechanism connected to the rotation shaft of the actuator; a spoiler connected to the link mechanism and provided so as to be pivotable between a deployed position and a retract position; and a spring attached to the spoiler and configured to bias the spoiler in a pivot direction in which the spoiler pivots toward the deployed position in which the spoiler pivots toward the deployed position when the rotation shaft of the actuator rotates forwardly, and pivots toward the retract position when the rotation shaft of the actuator rotates reversely, and the actuator is provided such that the rotation shaft is rotatable reversely by an external force applied to the spoiler in a pivot direction in which the spoiler pivots toward the retract position.
