Zusammenfassung:	PURPOSE:To increase and stabilize bonding strength by charging a specified curable composition between a rotor and a shaft, and curing a squeeze-out portion by UV ray irradiation followed by complete cure of the residual portion. CONSTITUTION:A UV ray-curable, anaerobically curable composition consisting of 100pts.wt anaerobically curable acrylate resin, about 0.1-10pts.wt. org. peroxide such as benzoyl peroxide and about 0.1-10pts.wt. photosensitizer such as benzoin, is used. Said curable composition is charged between rotor 2 constituted of a plurality of iron pieces 2' and shaft 1. Then after fillet 4' is formed by curing squeezed composition 4 by UV ray irradiation, the entire composition 4 is cured completely by heating at about 120 deg.C for about 20min, to firmly bond the rotor 2 to the shaft 1.
