To precisely correct positional shifts in two directions of longitudinal and lateral directions in formed bodies of baked and unbaked products in a manufacturing process of sanitary earthenware.

The device is provided with a grasping means for grasping the formed body, a conveying means for conveying the formed body to the next process under the condition where the body is grasped, an advancing- directional position correcting means for correcting an advancing-directional position of the formed body, a right-angle directional position correcting means for correcting a right-angle-directional position right-angled to the advancing direction of the body, a position detecting means for detecting a coordinate position of the right-angle-directional position for conveying the formed body to the next process under the condition where the body is grasped, and a control means for controlling the right-angle-directional position correcting means to bring the formed body into prescribed coordinates when the body is conveyed to the next process, based on a detection signal by the position detecting means.
