摘要： A skirt section has a plurality of substantially elliptic projections and a recessed portion formed on an attracting surface thereof. The skirt section is separated from each other by predetermined spacing distances along a circumferential direction of the skirt section on concentric circles. The recessed portion enables a fluid under the negative pressure to be supplied to the entire attracting surface except for the projections. Even if oil film or water droplet adheres to an attracted surface of a workpiece, the workpiece can reliably be attracted without causing a slip.

摘要： A suction apparatus includes an opening/closing valve for supplying a negative pressure fluid to a pad section when one end of a valve rod abuts against a workpiece to make a change from a valve-closed state into a valve-opened state, and a lead switch for detecting that the opening/closing valve is changed from the valve-closed state into the valve-opened state. Once the lead switch is in the ON state, it is possible to detect that the workpiece is certainly attracted by the pad section.
