Problems solved by technology
[0004] However, with the further miniaturization of electrical products and hard disk drives, people are pursuing space saving of the gasket installation surface and the resulting narrowing of the gasket body. Not only that, the box-shaped body has also been changed from the conventional casting. It is a miniaturized and thinner product that is pressed and formed from a metal sheet. As a result, the width of the end surface of the box-shaped body that is in contact with the gasket is greatly limited. In the gasket of the above shape, the lip and the box-shaped The body may not be in normal contact, resulting in poor sealing
[0005] Due to the thin plate of the shell, due to the rebound force of the gasket during assembly, the shell will undergo excessive flexible deformation between the pitches of the fixing screws. lead to poor sealing

Embodiment Construction
[0046] Referring to the following figures, the best implementation of the present invention will be described. However, the scope of application of the present invention is not limited to the above-mentioned embodiments, nor is it limited to the content described in the examples.
[0047] As shown in FIG. 1 , one part, namely the shell 1, is formed by pressing a thin metal plate. There is a peripheral wall 12 around the bottom surface 11. The material of the shell 1 is steel such as aluminum plate and stainless steel plate.
[0048] The other parts, namely the box-shaped body 2, are formed by pressing and processing thin metal plates, and are used to accommodate electronic components. There is a peripheral wall 22 around the bottom surface 21, and the inner end surface 23 of the front end portion 24 of the peripheral wall 22 forms an inclined surface that expands outward. 25. The material used for the box-shaped body 2 is steel such as aluminum plate and stainless steel plate...

A gasket (3) enabling the secure contact of a box type body (2) thereon even if both the box type body and a cover (1) are reduced in size and thickness and preventing a fluid from leaking through a seal since the repulsion of the seal when it seals a clearance between two members (1, 2) is small and the cover (1) is not excessively deformed and a structure for sealing the clearance between the two members using the gasket. In the gasket (3), a body (31) is adhered to the bottom face (11) of the cover (1) with a peripheral wall (12), and a step face (36) is formed by the body (31) and a lip part (32) formed on the tip side of the body. A contact surface (35) is formed by the side wall (34) of the body (31) and the peripheral wall (12) of the cover (1), and the step face (36) is positioned on the outside of the lip part (32).
Description
technical field [0001] The invention relates to an electric appliance, in particular to a gasket for sealing between a box-shaped body accommodating a hard disk drive and a casing, and a sealing structure between two parts using the gasket. Background technique [0002] For a long time, castings have been used for box-shaped bodies used in electrical products to accommodate hard disk drives. Both the contact surface of the gasket and the width of the gasket tend to be narrowed. [0003] In the following patent documents, it is proposed to set the cross-sectional shape of the gasket to be composed of a base and a protrusion, and to set the ratio of the width and height of the gasket to ensure the sealing performance of the box-shaped body and the gasket. [0004] However, with the further miniaturization of electrical products and hard disk drives, people are pursuing space saving of the gasket installation surface and the resulting narrowing of the gasket body. Not only tha...
