Damage caused by displacement of a rotating shaft is prevented with an acceleration sensor. A centrifuge according to the present invention includes a rotor, a driving source that rotates the rotor, a rotating shaft that links the rotor with the driving source, an acceleration sensor, and a control unit. The acceleration sensor outputs a value indicating acceleration in at least two different directions which are orthogonal to an axial direction of the rotating shaft. The control unit obtains a displacement conversion value corresponding to a value, which is obtained by dividing a value which is proportional to acceleration based on a value indicating acceleration and outputted by the acceleration sensor, by a value which is proportional to a square of an angular velocity of the rotor, and stops rotation of the rotor when the displacement conversion value satisfies a displacement determination criterion which is predetermined and indicates that displacement is large.
