ABSTRACT:
A rotor mounting structure arranged in a centrifugal separator. A cylindrical shaft having elastic tongue pieces provided substantially equidistantly on the peripheral edge of the upper surface of the cylindrical shaft is provided at the distal end of a drive shaft; the tongue pieces have hooks; a shaft accommodation orifice accommodates the cylindrical shaft is formed in the center of the rotor; elastic tongue piece insertion grooves mate with the elastic tongue pieces of the cylindrical shaft; the rotor is joined to the cylindrical shaft, while bending the elastic tongue pieces; and in a state in which the rotor is completely joined to the cylindrical shaft by engaging the hooks of the elastic tongue pieces with the upper edges of the grooves of the rotor by the elastic force of the elastic tongue pieces.
