Abstract:
Provided is a technique which makes it possible to produce a bearing unit with higher accuracy. A hub unit manufacturing device (30) comprises: a shaft press-fitting part (51) configured such that, in a state where an inner ring support base (42) is disposed facing an inner ring (11) at one end in the central axial direction of a bearing unit (10), where a hub main body (2) is disposed on the side opposite the one end in the central axial direction of the bearing unit (10) such that a tip end of a shaft part (3) is made to face an inner ring (12), and where the tip end of the shaft part (3) is in contact with an inner circumferential surface of the inner ring (12), the shaft press-fitting part presses the hub main body (2) toward the inner rings (11, 12) so as to press and secure the inner rings (11, 12) to the inner ring support base (42), and press-fits the shaft part (3) to the inner circumferential surfaces of the inner rings (11, 12); and an outer ring rotation driving part (61) that causes an outer ring (13) to rotate about the center axis of the outer ring (13) while the inner rings (11, 12) are pressed and secured to the inner ring support base (42).
