PURPOSE:To perform the assured assembling in a simple constitution and to reduce the variance of performance by providing a holder and a magnet at the rear edge of a cantilever and fixing the rear suspension part which extends to the back side of the holder at the rear edge of a sleeve after a thermal deformation. CONSTITUTION:A rear suspension part 15 which is unified with a holder 11 is inserted into the center hole of a sleeve 12 made of a nonmagnetic material via a damper 8. A rod part 15b forming the part 15 of the holder 11 is partly projected from the rear end of the sleeve 12, and a damping effect is applied to the damper 8 by giving proper pressure to the damper 8 from the front part of the holder 11. Under such condition, the rear projected part of a rod-shaped part 15b of the holder 11 is deformed by heat to form a stopper part 13 and then cooled and fixed firmly. |
