Abstract
A device according to the present disclosure is a workpiece retaining device 10 that retains a retained portion 110 of an axial-directional end portion of a workpiece 100 that is cylindrical. The workpiece retaining device 10 includes a core member 32 that is round and that comes into contact an inner perimeter face of the retained portion 110 of the workpiece 100, a pressing member 33 that presses an outer perimeter face of the retained portion 110 of the workpiece 100 to an inner side in a radial direction, and an aligning member 44 that, upon a pressing force from the pressing member 33 acting thereupon, allows the core member 32 to move in the radial direction, in accordance with a magnitude and a direction of the pressing force.
