A handling attachment includes four vacuum cups to suction-hold a suction target surface of a workpiece and a support member which holds the vacuum cups so as to maintain a position relation among the vacuum cups. A device for positioning the vacuum cups has a base plate and four positioning jigs disposed on the base plate. The positioning jigs have, at their upper end, a dummy workpiece surface to be abutted with the vacuum cups. The dummy workpiece surface is allowed to change the position and to tilt in any direction. |
