Wire support member and rotary disk storage device

摘要

One feature of the invention is to support a wiring structure on a side surface of an actuator arm used in a magnetic disk device so as not to allow fluttering to occur. In one embodiment, a wire support member 102 a used in a magnetic disk device includes a protruding wall 108 a provided with an opposing surface facing a wiring structure 90 a and protruding in a width direction, and a protruding wall 110 a provided with an opposing surface facing the wiring structure 90 a and protruding in a width direction. The wire support member 102 a is provided with a fixing area for accommodating the wiring structure between the opposing surface of the protruding wall 108 a and the opposing surface of the protruding wall 110 a. The wire support member 102 a is further provided with an open area adjoining the fixing area at a longitudinal end portion of the protruding wall and includes protruding walls 328, 330, 332 each having an opposing surface facing the wiring structure.
