摘要： PROBLEM TO BE SOLVED: To prevent breakage of a stator and a casing and to prevent breakage of a vacuum system caused thereby by providing a structure for releasing binding to a pump casing in circumferential or radial direction in a case where abnormal torque acts on a stator side on at least one portion of the stator in a turbo molecular pump. SOLUTION: During normal operation, a large torque does not act on a fixed vane 32 or fixed vane spacer 38 in circumferential or radial direction. A laminated structure of the fixed vane 32 and the fixed vane spacer 38 is bound by friction between each other and keeps its position. If abnormality occurs to rotation of a rotor for some reason and a large force is applied to fixed vane spacers 38a, 38b in circumferential and radial directions, the fixed vane spacers 38a, 38b are pushed outward. Then, a half spacer piece is separated and enters grooves 42, 44 in circumferential direction and the binding of other fixed vane spacer 38 against a stator S in axial direction is released. Accordingly, the fixed vane spacer 38 becomes freely rotatable. As a result, rotation energy of the rotor is absorbed thereby, and the rotor comes into a stop eventually.
