摘要： The present invention is a workpiece support device that supports a long workpiece when the long workpiece is conveyed in a longitudinal direction. This device includes: a shaft member rotatable about a shaft rotation axis extending along the longitudinal direction; at least one support member including a support roller that is rotatable about a roller rotation axis provided in an orthogonal surface orthogonal to the shaft rotation axis and that is configured to contact a side surface of the long workpiece and support the long workpiece; a reciprocating mechanism provided at a position corresponding to the foregoing, having one end mounted on the at least one support member, and configured to reciprocate in a predetermined expansion-contraction axis direction; and a connecting rod having one end rotationally movably mounted on the at least one support member and having another end rotationally movably mounted on a side surface of the shaft member.
