PROBLEM TO BE SOLVED: To provide a rotor which has an assembly structure including a body part formed of ceramics and having an insertion hole part, a shaft part inserted in the insertion hole part of the body part and fixed, and a fixing part fixed on the shaft part and abutting on the body part, wherein the rotor includes a rotation stopper capable of preventing the body part from rotating on the shaft part while preventing breakage of the body part, and has a simpler structure.SOLUTION: A rotor has the assembly structure including: the body part formed of ceramics and having the insertion hole part; the shaft part inserted and fixed in the insertion hole part of the body part; and the fixing part fixed on the shaft part and abutting on the body part. The body part includes a cutout-like engaged part formed on a part of an outer circumference edge at an end. The fixing part includes a body part having a side surface arranged on one side in a direction along an axial center of the body part, and an engaging part arranged so as to project from the side surface of the body part. The engaged part of the body part and the engaging part of the fixing part are engaged. |
