PURPOSE: To improve the soldering joining strength and the quality of a rotor, by a method wherein two sets of pin hole pairs are formed in a portion facing a joint between a pair of rotor constituting members, and a positioning pin having specified properties is mounted in each pair of the pin holes. CONSTITUTION:In a portion facing a joint between a pair of structure parts with a rib 10a and 10b positioned facing each other with a joint there between, two sets of positioning pin pairs, positioned facing each other, are formed in a position where the periphery of the end surface of a boss part 4b is divided into two equal parts. Two sets of positioning pin holes pairs, each positioned facing each other, are formed in a portion, facing a joint between the structure parts with a rib 10a, 10b and side wall structure parts 9a, 9b and in a position where the periphery of the end surface of the boss part 4b is divided into two equal parts. A silver solder is nipped between three joints, and a rotor 4 is heated to join the joint. This constitution enables improvement of the soldering joining strength and the quality of the rotor.
