Abstract:
The present invention provides a stator component of a vacuum pump, which is suitable for reducing the fracture energy (energy of fracture that occurs when a rotor of the pump is damaged during its rotation) and the size of the pump, and also provides a vacuum pump having this stator component. In the vacuum pump, a spacer or of a thread groove pump stator, which is a stator component forms a gap satisfying the following <<condition>> between an outer circumferential surface of each of housed in a pump case of the vacuum pump, and an inner circumferential surface of the pump case, with the stator component being housed in the pump case. <<Condition>> 2d/D≤ε max , where D is the outer diameter of the stator component (spacer or thread groove pump stator), d is the width of the gap, and ε max  is the breaking elongation of the stator component.

Claim (Index 10):
The stator component of a vacuum pump according to  claim 4 , the stator component is made of aluminum alloy.
