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.
