[0004] In the camera cover structure disclosed in Patent Document 1, a gap is provided between the magnesium cover and the stainless steel body to form a non-contact structure except for the fastened portion. When using a waterproof camera etc. submerged in water, even if the periphery of the above-mentioned electrical connection is sealed, if there is a minute defect on the above-mentioned magnesium cover, since the corrosion potential on the side of the above-mentioned magnesium cover is low, there may be damage from this part. The possibility of corrosion initiation cannot be called a sufficient anti-corrosion countermeasure

The invention provides a waterproof apparatus whose exterior parts have different kinds of metals, which can restrain generation of corrosion at the status of moisture condensation or immersion in water, and has simple structure of exterior construction. A camera (1) as the apparatus has an air-tightly constructed camera body (2); left and right side covers (4,5) formed by the metal, which constitute an exterior portion covering the camera body; and a front cover (3) made of a conductive metal different from the metal of the left and right side covers, which constitutes an exterior portion covering the camera body. The front cover has an electrically conductive first field, which is part field contacted with the left and right side covers; a second field performing the nonconductor surfacetreatment; and a third field, which does expose to the appearance, is an electrically conductive field surface formed by peeling nonconductor surface in the second field, and can restrain the corrosion of the second field of the front cover even if the camera is immersed in water.
Description
technical field [0001] The present invention relates to a structure for preventing galvanic corrosion of the above-mentioned exterior parts in a device having exterior parts formed of different kinds of metals. Background technique [0002] Conventionally, in equipment having exterior parts made of different types of metals, there is a corrosion potential difference between the different types of metals of the above-mentioned exterior parts, and in the case of a structure assembled in a state of mutual contact, if When the surface is in a dew condensation state or in a state of being immersed in water, the exterior parts with low corrosion potential will be corroded (galvanic corrosion). For example, in equipment such as a drip-proof or waterproof camera that uses exterior components made of zinc alloy, aluminum alloy, stainless steel, etc., corrosion of the exterior components as described above cannot be avoided. Therefore, the camera cover structure disclosed in Patent D...
