Problems solved by technology

[0007] In view of the above points, the technical problem to be solved by the present invention is to prevent the uneven deformation of the cover due to the rebound force of the gasket while making the device casing composed of the base and the cover easy to be thinned. And the resulting partial surface pressure of the gasket is insufficient

Embodiment Construction

[0088] Fig. 1 is a partial cross-sectional view showing the first embodiment of the gasket sealing structure according to the present invention; The base of the accommodation portion 11 that can accommodate the unillustrated magnetic disk, magnetic head and its driving device; symbol 2 represents the cover that seals the above-mentioned accommodation portion 11 to the base 1 by a plurality of screw parts 3, and the base 1 and the cover 2 constitutes the housing of the HDD.

[0089] The cover body 2 can be made of a metal plate such as stainless steel or aluminum by stamping, and is composed of an upper plate portion 21 and a side plate portion 22 formed by bending substantially vertically along its outer periphery. And, the cover body 2 is embedded in the receiving portion of the base 1, that is, the side plate portion 22 of the cover body 2 is located on the inner peripheral side of the side plate portion 12 of the base 1, and the outer surface 22a of the side plate portion 2...

Abstract

A sealing structure sealing a clearance between a base (1) having a storage part (11) and a cover (2) joined to the base (1) so as to close the storage part (11) through a gasket (4) formed of a rubber-like elastic material. The base (1) and the cover (2) comprise side peripheral surfaces (12a) and (22a) opposed to each other in a direction different from a joining direction with a screw member (3). The gasket (4) is integrally fitted onto the side peripheral surface (12a) of the base (1) (or the side peripheral surface (22a) of the cover (2)), and the seal surface (41a) of the gasket is closely fitted to the side peripheral surface (22a) of the cover (2) (or the side peripheral surface (12a) of the base (1)). Thus, the outer shell of a device formed of the base (1) and the cover (2) can be easily thinned and the cover (2) can be prevented from being nonuniformly deformed by the repulsion of the gasket (4).

Description

technical field [0001] The present invention relates to a sealing structure, which seals between a base having an accommodating portion and a cover installed to close the accommodating portion on the base through a gasket made of a rubber-like elastic material. A sealing structure between a base and a cover in a hard disk drive (hereinafter referred to as HDD). Background technique [0002] For HDD, it is necessary to prevent dust and moisture from entering from the outside to prevent data from being written and read from the disk. Therefore, a gasket must be installed between the base housing the magnetic disk, the magnetic head for reading and writing data, its driving device, and the like, and the cover that closes it. [0003] Fig. 22 is a partial cross-sectional view showing a prior art gasket sealing structure. In this FIG. 22 , reference numeral 101 is a chassis in the HDD, and reference numeral 102 is a cover. In the base 101, an accommodating portion 101a contain...
