A sealed structure for an electronic device, the sealed structure includes a base, a concave cover enclosing electronic components of the electronic device when the cover is fitted to the base, and a gasket-like sealing member that fits between edge portions of the cover and the base to seal the enclosure. A rib portion is formed on at least one of either the cover or the base so as to prevent the sealing member from protruding from the edge portions of the cover and base, thus providing an improved seal.

Sealed structure for an electronic device

A housing includes a base plate and a metallic cover. The cover may be formed by deep-drawing. The housing accommodates, for example, a magnetic disk, a magnetic head, and a drive mechanism. The drive mechanism serves to displace the magnetic head with respect to the magnetic disk. When the cover is coupled to the base plate, a screw is screwed, penetrating the cover, into the tip end of the carriage axis for supporting a carriage. Vibration caused by swinging movement of the carriage is transmitted to the cover through the screw. A vibration absorber adhered to the outer surface of the cover is adapted to absorb the transmitted vibration. Noise may be suppressed in the seek operation.
