1. A workpiece support device comprising:
a shaft rotatable about a shaft rotation axis of the shaft and extending along a longitudinal direction of a workpiece;
a first support comprising a first support roller that is rotatable about a first roller rotation axis orthogonal to the shaft rotation axis and that is configured to contact the workpiece to support the workpiece;
a first reciprocating mechanism having one end connected to the first support and configured to reciprocate in a first expansion-contraction axis direction; and
a first connecting rod having one end and another end, the one end of the first connecting rod being rotatably connected to the first support, the another end of the first connecting rod being connected to the shaft such that the another end of the first connecting rod is rotatable together with the shaft.
