Abstract:
[Problem] To provide a tailstock unit which is used together with a processing unit capable of processing a long workpiece, and a spinning processing apparatus which comprises such a tailstock unit and is unlikely to be restricted in terms of an installation space by preventing an increase in the size thereof. [Solution] A tailstock unit 1 has: a tailstock shaft (support part) 31 that supports an end portion of a mandrel 11 in a state in which a central axis thereof coincides with a central axis of the mandrel 11 when a workpiece W mounted on the mandrel 11 is processed by a roller 12; a first movement mechanism 5 that moves the tailstock shaft 31 toward and away from the mandrel 11 in an X axis direction along the central axis of the mandrel 11; and a second movement mechanism 6 that moves the tailstock shaft 31 with respect to the mandrel 11 in a Y axis direction orthogonal to the X axis direction.
