  According to the waterproof housing having such a configuration, “when this waterproof housing is exposed to a low temperature atmosphere, moisture in the sealed space is condensed on the inner peripheral surface of the cylindrical body made of a material having high thermal conductivity. As a result, moisture is prevented from condensing on the inner surface of the outer transparent plate, and the inner transparent plate is insulated by the air present in the sealed space. The effect of preventing moisture from condensing on the inner surface of the film is obtained.

  However, in the structure in which the lens protection glass is integrated with the exterior body in accordance with the waterproof structure, if water or dust enters the inside of the protection glass, the exterior body must be removed to take them out. There is a problem that the work is very troublesome. Furthermore, if a special attachment method is used to attach the lens protection glass, it is necessary to distribute an attachment jig or the like for that purpose to service centers in various places. Therefore, there is a problem that it is a great demerit in terms of cost.

Also, if you try to attach the lens protection glass so that it can be removed and attached with screws, while maintaining waterproofness, not only will the number of parts increase, but the screw hole part will also need to be waterproofed. As a result, there is a problem that the entire apparatus becomes larger by the amount of the screw hole having a large number of holes, and the number of work steps in manufacturing is increased.
