摘要： A body and an arm are produced as separate components, a fitting recess and a flange are formed on the body, and a magnetic head mounting portion, a fitting portion capable of being fitted to and removed from the fitting recess of the body, and an engagement portion engaging with the flange of the body and prevented from falling off in an axial direction are formed on the arm. At least two fitting recesses are formed in an interval in the axial direction of the body. The arm is fitted to the body, and the fitting portion is molded by a resin to the body. A moving coil of a motor is molded to the body. The fitting portion of the arm is shaped into a ring shape. The fitting portion is shaped into the ring shape having a transverse opening. A rotary bearing having, or not having, a sleeve is fitted into a shaft hole of the body.
