A rotatable seat for a sucker has a stationary plate and a rotating plate. When in used, the stationary plate is attached to the platform of the car by tape or other ways. Because an outside surface of the rotating plate is smooth, the assistant device can be attached to the smooth outside surface easily and securely by sucker. Then the assistant device is connected securely to the platform. Because a mounting segment of the rotating plate is mounted in a mounting hole of the stationary plate, and multiple outside positioning segments on the mounting segment engage with multiple inside positioning segments on the mounting hole, the rotating plate and the stationary plate are relatively rotatable, and are selectively held at specific angles. Thus, the assistant device can be adjusted to a fine visual angle for the user on the passenger seat or the rear seat. |
