ABSTRACT:
A sealing and shielding structure of the present invention comprises an elastic sealing member and an electromagnetic shideling member provided in a cavity formed at least in one of a first member and a second member both of which have conductive abutting faces. The elastic sealing member is, for example, slightly larger than the electromagnetic shielding member so as to be pressed between the first and the second members. Accordingly, when the first and the second members are closed, the elastic sealing member is compressed and deformed to push the electromagnetic shielding member so that the electromagnetic shielding member closely contacts with the conductive abutting faces of the first and the second members. Consequently, the sealing and shielding structure can produce a prominent electromagnetic wave shielding effect because of the electromagnetic shielding member kept in close contact with the conductive abutting faces of the first and the second members.
