A holding device to hold a side portion of a conveyed workpiece; a running device to convey the holding device in a feeding direction along a rail; and a support mechanism to support the holding device at front portion and rear portions of the mechanism. Eccentric shafts are with the holding device at respective positions, at one position, one of front and rear portions is eccentric in the feeding direction by a predetermined amount relative to one drive shaft's axis included in the running device. At the other position, one of front and rear portions is eccentric crossing the workpiece feeding direction by a predetermined amount relative to one drive shaft's axis in the running device. The yawing occurring while the workpiece is conveyed, is corrected by rotating the axes of eccentric shafts axes such the holding device moves relative to the running device's position. |
