Spoiler device for vehicle

A spoiler device for a vehicle, comprising:

• a plurality of link mechanisms configured to support a spoiler via a plurality of rotatable link members in a deployed state where the spoiler protrudes from a surface of the vehicle;
• a driving shaft configured to connect each of the link members provided to be spaced apart from each other in a vehicle width direction, the driving shaft configured to change the deployed state and a retracted state of the spoiler by rotating each of the link members about an axis of the driving shaft;
• and
• a connection mechanism connecting an input shaft to which a driving torque of a power source is inputted and the driving shaft to transmit the torque therebetween:
• wherein
• the connection mechanism includes:
• a nut member being mounted to a screw portion formed on the input shaft, the nut member thereby moving in an axial direction in response to a rotation of the input shaft;
• and
• a connection member including a connection portion moving in a circumferential direction about the axis of the driving shaft in response to a movement of the nut member in the axial direction, the connection member integrally rotating with the driving shaft.
