A centrifugal machine includes a vibration preventive mechanism part containing a support member and a damping portion disposed in the support member so as to be connectable or contactable to the drive device. The damping portion includes a magnet member and a friction member disposed on the support member and, owing to the magnetic force of the magnet member, the friction member is contacted with a first arm member. The magnet member can be magnetized by an electromagnetic coil and, owing to the magnetic force of the magnet member, the friction member can be contacted with the first arm member. On receiving a vibration change from a drive device, the vibration preventive mechanism part can dampen the vibration change using the damping portion.
