Abstract: When this centrifuge is operated, local stress applied to a liquid-feeding groove formed in the upper surface of a rotor core is averaged to minimize deformation of the rotor core. A rotor core, which is mounted inside a rotor used for continuous centrifugation, has a columnar solid section, blades expanding radially outward from the solid section, and a disc section extending radially outward from the upper surface of the solid section, the upper surface of the rotor core being provided with a liquid-feeding grove that continues radially outward from the center vicinity to the outer side. A stress-mitigating groove that extends radially outward is formed in the lower surface of the liquid-feeding grove. The stress-mitigating groove is formed in a position overlapping the position of the liquid-feeding grove when the disc section is viewed along the axial direction.
