Abstract
A water-resistant camera comprising a main body part and a rear cover part having a film clearance space between them to permit movement of successive sections of a filmstrip across a backframe opening in the main body part, and a water-resistant casing part spaced over the rear cover part, is characterized in that the water-resistant casing part has continuous stiffener-rib means which surrounds a limited portion of the water-resistant casing part that is opposite the film clearance space, for preventing the limited portion from being bent inwardly against the rear cover part to in turn bend the rear cover part inwardly into the film clearance space when the water-resistant camera is underwater.
