In a process of conveying an object to be conveyed, contact of the object with a base body and a swirl flow forming body is avoided to prevent damage to the object. A swirl flow forming body (1) provided with a through-hole (11) penetrating therethrough from the front surface to the rear surface thereof and having a circular lateral cross-section, first discharge openings (14a, 14b) for discharging fluid from the inner peripheral side surface of the through-hole (11) to generate a swirl flow, and second discharge openings (16a-16d) for discharging the fluid upward from a flat plate section (18). Even if buoyancy generated by the swirl flow from the first discharge openings (14a, 14b) is insufficient, glass (3) can be supplementally levitated by the upward flow from the second discharge openings (16a-16d). Accordingly, even if an edge of the glass (3) overlaps on a part of the swirl flow forming body (1) in a process of conveying the glass (3), contact of the edge of the glass (3) with the swirl flow forming body (1) can be avoided. |
