A rear end of the movable flow adjustment portion is moved upward with movement of the movable flow adjustment portion from the front position to the intermediate position. The rear end of the movable flow adjustment portion is moved downward with movement of the movable flow adjustment portion from the intermediate position to the rear position. A height position of the rear end of the movable flow adjustment portion at the rear position is lower than a height position of the rear end of the movable flow adjustment portion at the front position. ## Claims ### Claim 1 A spoiler structure comprising: a base portion that is attached to a vehicle body; and a movable flow adjustment portion that is moved relative to the base portion from a front position on a vehicle front side to a rear position on a vehicle rear side via an intermediate position, wherein a rear end of the movable flow adjustment portion is moved upward with movement of the movable flow adjustment portion from the front position to the intermediate position, the rear end of the movable flow adjustment portion is moved downward with movement of the movable flow adjustment portion from the intermediate position to the rear position, and a height position of the rear end of the movable flow adjustment portion at the rear position is lower than a height position of the rear end of the movable flow adjustment portion at the front position. ### Claim 2 (depends on 1) The spoiler structure according to claim 1, wherein the movable flow adjustment portion includes a link mechanism between itself and the base portion, and the link mechanism moves the movable flow adjustment portion to the front position, the intermediate position and the rear position, in a series of operations. ### Claim 3 (depends on 2) The spoiler structure according to claim 2, wherein the link mechanism is configured such that turning of the link mechanism in one direction moves the rear end of the movable flow adjustment portion upward and then downward with the movement of the movable flow adjustment portion from the front position to the rear position via the intermediate position. ### Claim 4 (depends on 1) The spoiler structure according to claim 1, wherein the base portion is provided at a roof rear edge of the vehicle body. ### Claim 5 (depends on 1) The spoiler structure according to claim 1, wherein a front end of the movable flow adjustment portion is in contact with the base portion and is continuous with a roof rear edge of the vehicle body in a vehicle front-rear direction at the front position. ### Claim 6 (depends on 1) The spoiler structure according to claim 1, wherein the base portion includes a lamp body portion, and the movable flow adjustment portion is arranged above the lamp body portion. ### Claim 7 (depends on 6) The spoiler structure according to claim 6, wherein the rear end of the movable flow adjustment portion is arranged above the lamp body portion at the rear position. ### Claim 8 (depends on 1) The spoiler structure according to claim 1, wherein the movable flow adjustment portion includes a rear end lamp body portion at the rear end.
