Zusammenfassung:	A device for treating a disc-like article with a fluid, including elements for dispensing a fluid onto the article and a chuck for holding and rotating the article around an axis perpendicular thereto, the chuck including a base body, a drive ring, and gripping members for contacting the article at its edge. The gripping members are eccentrically movable with respect to the center of the article and driven by a drive ring rotatably mounted to the base body so that the drive ring is rotatable against the base body around the axis. The relative rotational movement of the drive ring against the base body is carried out by either holding the base body and rotating the drive ring or by holding the drive ring and rotating the base body, whereby the to-be-held-part (drive ring or base body) is held without touching the respective to-be-held-part by magnetic force.
