Title:
ACTUATOR FOR DRIVING HEAD IN HARD DISK DEVICE
Document Type and Number:
Japanese Patent JPH05307842
Kind Code:
A
Abstract:
PURPOSE:To reduce cost for changing parts and cost for manufacturing. CONSTITUTION:A boss 25 is provided in the arm connecting part of a suspension arm 24; and a head arm 22 is provided with a notched part 23 comprising an arm attaching hole 23a with an inner circumference that is in a pressurized contact with the boss 25 and a slit 23b that is communicated with the arm fitting hole 23a. Consequently, since a portion in the proximity of the notched part 23 is elastically deformed at the time of attaching and detaching the arm and the boss 25 is made detachable against the arm fitting hole 23a, when a part of the head is no longer used, only the suspension arm 24 corresponding to this head can be changed independently. Also, through the capability of attaching and detaching the arm by elastically deforming the head arm 22, the ball which is highly accurate in size and which is conventionally required for connecting the arm is no longer needed.
