Abstract
An actuator arm assembly in which a spacer is designed to absorb a stress occurrable during a caulking operation so that the spacer will not be deformed. The actuator arm assembly includes a base; an actuator arm rotatably mounted on the base and having a first hole at one end thereof; a load beam supporting a magnetic head at one end thereof and having a second hole at the other end; and a spacer firmly secured to the other end of the load beam and fixedly caulked to the one end of the actuator arm. The spacer includes a flat portion, a cylindrical portion integral with the flat portion, and an annular groove formed between the cylindrical portion and the flat portion. An inner diameter of the cylindrical portion at its distal end portion is slightly smaller than the diameter of the caulking ball.
