ABSTRACT:
The centrifuge of the present invention is a centrifuge wherein a rotor is engaged integrally with a drive shaft, in the direction of turning, so that it can be freely attached and detached, wherein the drive shaft is attached to the equipment frame through elastic members, a spherical surface is formed in the upper part of the drive shaft, a spherical concave surface corresponding to the spherical surface in the drive shaft is formed in the top surface of a bearing hole in the rotor, the spherical concave surface of the bearing hole is made to ride on the spherical surface of the drive shaft, and the rotor is engaged so that it can swing freely relative to the drive shaft.
