摘要： Material for a connecting rod for an internal combustion engine is carburized and quenched, a carburized layer formed on the bearing portion is ground until the portion which exhibits the maximum compressive residual stress, and a shot-peening processing is performed on the ground surface. The invention produces a bearing portion having surface characteristics in which maximum compressive residual stress is imparted, and therefore, remarkable improvement in the fatigue strength in the bearing portion can be obtained. Furthermore, a large number of concavities formed by the shot-peening processing can be efficiently employed as an oil reservoir, so that sliding properties and lubrication can be improved, and the occurrence of problems such as fretting corrosion, galling, and seize can also be solved, and the galling and problems of the seize can be prevented.

摘要： A metal film 4 is disposed between a permanent magnet 3 and a rotor yoke 1, and the permanent magnet 3 and the rotor yoke 1 are subjected to beam welding. Since the metal film 4 is disposed between the permanent magnet 3 and rotor yoke 1, and the metal film 4 as a laser beam irradiated portion is melted by vacuum beam or laser beam, the metal film 4 has brazing metal function in welding, so that the connection between the permanent magnet 3 and the rotor yoke 1 is strong. Since there is no need of embedding the permanent magnet 3 in the rotor yoke 1 and there is no need to use polymer adhesives, the cost can be reduced.
