PURPOSE:To prevent the breakage of a rotor at a part connected to a shaft by a method wherein a member, having an elasticity capable of absorbing a stress in the relative displacing direction of the rotor and the shaft, is interposed between the rotor and the shaft. CONSTITUTION:The first rotor 2 of ceramic is fitted into a housing 1 by means of loose fitting at a position where the driving shaft 6 is accommodated in the housing 1 through a split pin 15. The split pin 15 is inserted into the shaft in a direction orthogonal to the axial direction of the shaft. The second rotor 3 of ceramic is fitted by means of loose fitting through the split pin 15 in the same manner as the rotor 2 so as to be engaged with the rotor 2. If there are deviations between the pin holes provided on the shafts 6, 7 and the same holes provided on the first and second rotors, these deviations may be absorbed by the deformations of the split pins. |
