ABSTRACT:
A structure in which when a rotating member is broken, an impact force is prevented from being concentrated to a local portion by enabling to receive a debris by a wide area at an instant and breaking energy can further be facilitated to consume. Further, according to a centrifuge attached with a cooler, the problem can be achieved to resolve by utilizing an insulating layer at an outer periphery of an evaporator as a space of deforming a guard cylinder when the rotating member is broken.
