Abstract
A workpiece transport device is used in a press machine. The workpiece transport device includes a pair of supports and drive mechanisms. The pair of supports support a holder useable to hold a workpiece, so as to allow movement in a transport direction of a workpiece. The drive mechanisms are provided to the pair of supports. The drive mechanisms are configured to move the supports in an up and down direction and a width direction. Each drive mechanism includes a first drive component and a second drive component with each including an electric motor as a drive source, a first link mechanism connecting the first drive component and the support, and a second link mechanism connecting the second drive component and the support.
