Abstract
A workpiece holding device includes a plurality of holding claws configured to hold a workpiece, and holding cylinders as claw opening/closing members configured to displace the holding claws in a direction closer to or away from a first workpiece. The holding cylinders are provided for the holding claws, respectively. Therefore, the plurality of holding claws can be opened/closed individually. The holding cylinders are held on a support disk as a holding member in a movable manner. That is, by moving the holding cylinders to arbitrary positions on the support disk, the holding cylinders are positioned fixedly.
