ABSTRACT:
A water-resistant camera comprising a main body part having a rear back frame opening across which successive sections of a filmstrip are moved to be exposed, a rear cover part lighttightly covering the backframe opening, and a water-resistant casing part spaced opposite the rear cover part, is characterized in that the main body part has spacer projections separate from the backframe opening for abutting one side of the rear cover part which faces the backframe opening, to maintain a film clearance space between the backframe opening and the one cover part side for movement of successive sections of the filmstrip across the backframe opening, and the rear cover part has support projections aligned with the spacer projections, on another side of the rear cover part which faces the water-resistant casing part, whereby when water pressure tends to press the water-resistant casing part inwardly toward the rear cover part the support projections will cooperate with the spacer projections to prevent the water-resistant casing part from pushing the rear cover part substantially into the film clearance space.
