る。(Embodiment 1) In FIG. 1, reference numeral 2 denotes a sintered metal which is formed integrally with the upper and lower parts and which is not impregnated with a lubricating oil. The cylindrical magnet 1 is inserted into the outer periphery of the sintered metal 2 and fixed to each other by the adhesive 3. Thereafter, the sintered metal 2 is impregnated with lubricating oil, and the lubricating oil attached to the outer periphery of the cylindrical magnet 1 is removed by a centrifugal separation method or the like.
【００１０】次に、円筒カップ形状のフレーム４の天面

に、接着剤３は高めの粘度を選定する必要がある。When the cylindrical magnet 1 is bonded to the sintered metal 2 previously impregnated with lubricating oil, the lubricating oil does not adhere to the outer periphery of the cylindrical magnet 1, so that the above-described step of removing the lubricating oil is not necessary. It is necessary to select an adhesive so that the adhesive force of the adhesive 3 is not reduced by the lubricating oil attached to the outer periphery of the sintered metal 2. Also, the sintered metal 2
Since the adhesive 3 has a large number of holes, it is necessary to select a higher viscosity for the adhesive 3 so that the adhesive 3 does not penetrate a large amount into the holes and hinder circulation of the oil in the sintered metal 2. There is.
